general and advanced taxonomy classes / natives featured at Oct. Hammond event

 

For those wanting to learn more about native plants and natural things, several events are upcoming that might be of interest. Dr. Charles Allen, one of the leading experts on native plants in the southeastern U.S. is holding a series of four fall native plant identification workshops, starting with the first, general plant ID starting tomorrow, Tuesday the 15th, in the metropolis of Pitkin, Louisiana. These are intensive two day and a half day workshops intended as brain expanding exercises in natives. I will be taking the Asteracea / Fabacea class on October 30- Sept 1st. Cannot wait!!!!

Dr. Allen, who has literally written the books on natives. see the link

Aslo worthy of a field trip is the Horticultural Field Day held on October 7th at the LSU Hammond Research Garden. Dr. Yan Chen and Dr. Allen Owings and others will be leading tours of their trial gardens once again. If you haven’t seen these gardens, and you make time to attend, I think you will agree that there is a lot to see and much to learn from a trip there, even if you can’t make it there that day. The gardens are open most every working day of the year. Bring your questions about you plants and gardens and meet these knowledgable folks.

Dr. Yan will be highlighting her work with native plants using local-sourced seed, which is really substantial and cutting-edge stuff! Go Tigers!

local seed; its a natural

Collected lots of great seed from the farm yesterday. Dreamed of doing this when I was just a wannabee, back in the day. I planted giant gardens of Narrow-leafed Mountain Mint, Rough Coneflower, Spearmint scented White Mountain Mint (Malcolm Mint), Ashy Sunflower, Tall Tickseed, and copious amounts of Lindhiemer’s and Wild Bergamot Bee Balm all those years ago at the seed farm in Mississippi. It is such a treasure-pleasure to mechanically harvest from those seed fields. I hope in time that more folks do this sort of thing. That was the goal for me, not only to make a living from locally sourced native seed  produce on seed fields on my own land but also to provide a model for others to copy before I go to the big aster garden in the sky. It has worked so far. whoop-whoop!

IMG_7946

above, a bundle of White Leafed Mountain Mint, one that I named “Malcolm Mint” about 15 years ago, since Dr. Malcolm F. Vidrine, who I named it for, was the one to find it in the wild, propagate it, conserve it and pass it on. When I drive through my fields, and crush the Malcolm Mint plants with my tractor tires, the world fills with the heavenly sweet-scented aroma of Spearmint, a sensory delight, I must say.

Similar in sensory over-load is the field of Frey Prairie genes that I planted back in 2000. Loaded with Sweet Goldenrod, one of our most useful and wonderfully scented herbs, Sweet Goldenrod, sometimes called Licorice Goldenrod is so amazing in that it transports your up onto a super-sweet scented cloud high above, when you step your feet across the field. Oh, high horticulture, how I love you! Frey Prairie is now fully extirpated; gone,  plowed under into a rice field. But my seed field has its genes, and all the texture, color, scent and diversity of what Frey once was. Its a gene-pool bank of sorts. in order to plant this field, I harvested the seed from Frey, the once, most-hallowed piece of ground. above, the golden yellow pyramidal heads of Sweet Goldenrod and the purply-pink square heads of Rough Button Blazing Star are complimentary, no doubt.

sweet video of me cleaning Geen Milkweed (below) that I roadside-rustled with Gail Barton last week. Sent my share off to entemologist Dr. Jovonn Hill at Mississippi State for a Balck Belt prairie pollinator planting project he’s doing. photos above are top left, clockwise, Green Milkweed in fruit, then in full seed, cleaned seed, and a massive plant that Gail and I were so impressed with. It was probably oder than she and I put together. It was a giant specimen with a bunch of seed, wrapped nicely on the highly flammable hair-like material that catches the wind and flies the seed off into the air. seed cleaning video uploaded onto my youtube channel.

speaking of locally native seed. a photo above of Cardinal Flower that occurred on its own in the yard this year, a great surprise, especially since I had bought in a few plants from a nurseryman, knowing they’d been shipped from a grower out of our region. Those bought plants were chewed incessantly by rabbits, so much that they are still nubbed to the ground all summer and still are. These plants, above, I found as seedlings while I was mowing one day this spring and kept the mower blades away from them. The rabbits don’t seem to want to try these. Yet. Maybe I’ll get some seed from them….

KCB’s controlled burn result of the Blue Swamp Creek Nature Trail park is quite obvious. In the distance, see toasty Loblolly Pines, Tallow Trees and mixed vegetation. The fire opened up the landscape magically, removing several years of fuel that had built up, hiding the herb plants from the sun. In the foreground is the future Pitcher Plant flatwoods restoration area. The park is modeled after the North Carlolina Botanical Garden in Chapel Hill and the University of Wisconsin, Madison, the first Arboretum in the country that established a naturally designed and managed arboretum.

last but not least, a vase of Candy Rain Lilly, Salvia and Sweet Coneflower for my sweetie, Sweetheart and wife, Candi, for the kitchen bar-counter. The amazing Sweet Coneflower, typically a plant found in wetter sites, was subjected two months of no rain, severe drought! and didn’t miss a beat when it came time to flower. That’s a drought with searing tempts that mostly reached 95 degrees every day, with at least one day at 104 degrees with a heat index of 120, yet it was happy as a clam in the ocean. Natives rock.

 

 

 

 

wheels on new Louisiana Children’s Museum design, rolling

Several, okay many, wonderful things happened this week in the life of Pastorek Habitats, the business. But best part of the week, as always, is like yesterday, when all the work was done and I made an early-morning break for the Mississippi state line; Pearl River County, that is, for some George W. Bush-like rest and relaxation (only in a Murica!).

Down on the farm its always like heaven on Earth for me. I got a chance to do some spraying in what is to be a new experimental planting area, getting ready for planting next year. Got to walk the prairie gardens. Lots of butterflies, everywhere. Go Micro-Prairies!!

One of the most exciting things to happen this week work-wise was my phone meeting with Architects Debra Guenther and Christian Runge with the firm Mithun. Mithun was chosen for the design of the new Louisiana Children’s Museum which will be located on eight acres in City Park, New Orleans, near the Museum of Art and the Botanical Gardens. Mithun has offices in San Fransisco and Seattle and they’ve been working with the Children’s Museum on the development of the idea of a new facility for several years.

Mithun is an interdisciplinary firm of architects, landscape architects and interior designers, providing integrated design of all those services on the project. Biohabitats’ roll is that of water resource ecologists for the project and Pastorek Habitats as the native plants and soils ecology. Its a real honor to be included in this short list of team members.  🙂

The design process is in full swing and should be finished, with working specifications completed within the next ten months or so.

Behind it is Sweet Coneflower, Rudbeckia subtometosa, the dark green in the center background, with course-textured Velvet Panicum, Panicum scoparium on the left and the bluish leaves of Switch grass, Panicum virgatum on the right. This is in the garden, at the house in Covington, Louisiana.

IMG_3339(2)

Before I knew what Winter Bentgrass was, I called it Mississippi Tumbleweed because I lived my early adult years, 26 years, in Pearl River County, Mississippi and I always saw it collect on the fence rows in cow fields. The stem of the inflorescence, breaks, becomes detached, and floats away-rolls away in bundles, in the wind, often collecting in large windrows at the field edge. Its a beautiful thing, Winter Bent grass is. Its motional. It moves in the landscape and then around the landscape.

IMG_3273

cool pic of the flower of Mottled Tuberose, Manfreda variegata (foreground), with my son Cale’s “tornado pot” and my ceramic sculpture “Family”, on yellow pedestal. The Tuberose is such a great garden plant, a native of Texas-northern Mexico. I got my start many years ago from Texas nurseryman and radical garden designer Will Fleming. The flowers are all stamen and really unusual but its all about the foliage of Mottled Tuberose. Its like a giant Manfreda virginica, but with dark green leaves that are strap-like and often, 12 to 18 inches long. The rosette of leaves grows low and flat to the ground, no more than a few inches tall; perfectly prostrate, covering a circle of ground and eventually making pups that pop-up from the root. Coolest plant ever? Maybe. Best plant ever? Probably.

Mr. Fleming selects for the really mottle leaf forms since the seedlings vary greatly from heavily mottled to nearly mottless. He likes to put those showy ones in his gardens.

IMG_2564(2)

Here’s a garden with Mottled Manfreda that I planted five years ago in the native garden area at City Park Botanical Garden, New Orleans. It was budding-up a couple of weeks ago when I visited. Mexican Primrose, the pink carpet surrounding it, in spring full-glory.

Eunice prairie demonstration gardens tour, April 4

The Cajun Prairie folks will hold their spring wildflower tour on April 4th, celebrating the prairie, lead by the two pioneering biologists who started the Eunice Prairie Restoration garden nearly twenty eight years ago. In my opinion, this is one of the top 3 public garden destinations in the state of Louisiana. Society members burned the site for the first time in two years this February and we had an intense fire as a result. It is always a beautiful site to see the prairies during the first week of April, at peak spring bloom; not much created by man in these parts compares. Imagine ten acres of the most beautiful garden you can conceive of and thats pretty much what you’ll see at Eunice in April. Remember Dorothy and friends in The Wizard of Oz walking through the poppy fields? Well, its much better than that. Heavenly, hallowed ground it is.

From this site, this planting, much of the research on seeded prairie landscaping in the Gulf South has been garnered. Many scientific papers have been produced via this single experiment. And many prairies have been produced with seed from it. This is a preserve managed for the conservation of Louisiana Tall grass prairie genetic ecotypes.

The tour will begin at the Duralde restored prairie, a 350 acre prairie collaboration between the the Cajun Prairie Society and the U.S. Fish and Wildlife Service, Lacassine NWR. There you can see lots of acreage of natural coastal Tallgrass prairie seeded in 1995-6 and transplanted with rescue plants over many years from the now extinct Frey prairie remnant, just south of Eunice by the Society and other volunteers. There you can walk through seeded experiments and demonstration gardens planted as a research project in 1998. There’s also the two-acre demonstration garden designed by Dr. Charles Allen and myself, which will is unique to the southeastern U.S., an individual prairie species garden with 10 x 12 feet rectangular plots for all of the conservative species of the prairie to be managed in a mowed- grid form. This area was burned this year, first time in a few.

Program for Cajun Prairie Habitat Preservation Society

Cajun Prairie Habitat Preservation Society Spring Meeting and Tours-Saturday, April 4, 2015

8:00 AM: Tours of Duralde Restored Prairie. Directions: Take LA 13 north out of Eunice and after crossing a bridge, go about 1.5 miles and turn left onto La 374. If coming from the north on La 13, about 6 miles south of Mamou, just past the Fire Station, turn right onto La 374. Follow La 374 west and it will take a sharp right then a sharp left. After straightening out from the sharp left, go about 0.5 miles and turn left at the first double intersection.  You will be turning left onto a gravel road that is Navy Road.

Navy Road is about 2 miles from La 13. Follow Navy Road and it will take a sharp right and then will start a sharp left but you will not turn at the left but drive straight into Duralde Prairie.

10:00 AM: Eunice Restored Prairies; meet at the corners of Martin Luther King and East Magnolia and enjoy the best restored prairie in the United States. This site is north of U.S. 190 and east of La 13. For those of you coming from the north on La 13, turn left (east) at the first paved road (East Magnolia) to the east after you cross the railroad tracks in Eunice. Go a couple of blocks and the prairie is on your left. For those coming from the east on U.S. 190 turn right (north) at the first red/green traffic light and follow Martin Luther King Drive for a couple of blocks and the prairie is on your left. For those coming from the west on U.S. 190, follow U.S. 190 through Eunice and after crossing a railroad track, go to the next red/green traffic light and turn left onto Martin Luther King Drive (See above). For those coming from the south on La 13, when you reach the stop sign, turn right onto Maple Ave. Follow Maple for about 3 or 4 blocks and at the 2nd four way stop sign, turn left onto Martin Luther King Drive. Follow this street across U.S. 190 and see above.

horticulture-worthy strains of native grasses for Gulf-influenced landscapes

One of the best things to happen to me in my working career is to have been influenced by a bunch of keen plant people who appreciated and promoted genetic diversity. This influence has helped me see the plants in the landscape with a more discerning eye.

By having the gift of spending time in natural areas, I’ve come across some noteworthy strains of plants that I believe have horticultural promise. Some are genetically unique individuals like you and I and some are entire populations of a single species in a particular location, noticeably different than the typical. Some are just normal, run-of-the-mill.

Without Charles and his side-kick Dr. Mac Vidrine (and other concerned Biologists), this, and other fabulous prairie gardens around the Gulf Coast region could not have been conceived. photo by Jeff McMillian

Here are a few Central Gulf Coastal plains species and strains worth mentioning:

Switch grass– Switch grass is highly variable in the landscape. Often, when you see lots of it, you’ll see short and tall, upright and rounded, narrow-leafed and wide bladed, blue-leaved and green-leaved. You’ll see variations in color and texture in inflorescence (flower), too. I have a nice dwarf one in my garden that grows about three feet tall in fruit. cule. the old timey selection, Heavy Metal, has been a commonly available cultivar (genetic anomaly) in the hort trade since the mid-1990’s. Northwind, a selection from up above the Mason-Dixon, is an upright and tall form that stays at attention, like a soldier. Cloud Nine is another I’ve grown for many years, getting my first plant from Niche Gardens in the late 1990’s. Its a big sucker, nine ft tall (Get it?) about that wide, too. Dallas Blue I’ve had for several years now and its of course its blue foliaged and decent in that it doesn’t flop and kind of rounded in form and medium texture. A decent plant. I think the perfect Switch for gardens is a fat-fat leaved one about three feet tall and wide, but I haven’t come across it yet. Gail Barton of Meridian Mississippi found a killer selection of Switch on Highway 45 south of Brooksville, Mississippi a few years ago. It is a beautiful grass, a beautiful plant. Its steely blue foliage with a large form about five feet, in inflorescence and a nice fine textured effect when in fruit. The cool thing about Switch grass is you can do large areas from seed really easily. We offer a mix of Switch seed from populations in the Cajun Tallgrass Prairie of Southwest Louisiana. In two years time, you can produce acres of Switch in robust, nearly mature stands.

Little Bluestem grass is said to be (or used to be) the most common sun-loving grass in in uplands(out of the wet) in East Texas, Louisiana, Mississippi and Alabama. It is a high-conservative species, worthy more ornamental use. Northern climate American are and have been selecting for this plant for many years and because of that, people are using them and making economic benefits in horticulture and commerce. We down here in the South are contemplating the matter still. This is an vertically inclined plant plant, its prolific and the beauty of it is more obvious in numbers. You wouldn’t plant a single Bluestem plant in a garden. You’d plant twenty or forty at a time, for effect. There’s strength in numbers, you know. You use Little Bluestem en masse as a element in the landscape. I prairie ecology, little Bluestem is a climax species, providing copies amounts of plants that proliferate in the landscape and when managed well, become a sod. Foliage and stem characteristics are where Little Blue got its name; Blue stems with red nodes and sometimes, the blue color is absent and shades of green dominate a stand. Sometimes the blue color is so intense it looks silver colored. In November, after first frost, Little Blue turns Little Red, and late in winter turns Little Tan. The functional value though is where Little Blue captures its niche. It provides ecological services abound. An interesting note is that Little Bluestem, below I-10 in the Cajun Prairie is associated with facultative wetland species. Normally it is considered a non’-wet loving plant but obviously genetics have adapted to wet ecotones.

Broomsedge/ Virginia Bluestem – since Little Bluestem has been so devastated, Broomsedge (not a sedge at all) is now probably the most common sun-loving upland grass in Louisiana. Its an early succession plant, moved out (in a restoration) by late succession species, Little Blue, typically. However, Broomsedge has some relevance as far as landscaping and horticulture is concerned. It can be managed in perpetuity if done with some skill. It has a most colorful presence in the landscape in the winter; an unusual reddish tan colored foliage, different than Little Blue, and of a slightly different texture. Its easily distinguished by its flattened stem nodes.

Split Beard Bluestem –Split Beard is very similar in habit and form to Little Blue until it blooms and fruits. When in fruit, the trained eye can pick it out of a line-up from a couple of hundred feet way. On I-20, if you happen to catch it in fruit before the mowers come, it creates a cottony, visually-dazzling landscape, whipped by the wind of the semi trucks. The fruit persists for a month or two. A cool, cool plant for horticulture and wildlife.

PCD0001_IMG0008 p1020337_2

above: Split Beard Bluestem in fruit and in the field. click on photo to enlarge

Dwarf Elliots Bluestem -Elliot’s Blue is rarely, if ever, dwarf, but there is a stand of a dwarf strain that I have been closely monitoring for two seasons, now, at a restoration in Louisiana that has horticultural promise for the Gulf coastal plain since most of our Bluestem species get really tall, especially in a garden soil with no root-space competition. An interesting thing is that when you see either Split Beard or Elliot’s, you generally see the other in close proximity. Elliot’s Blue has a similar habit to Little Blue until it blooms and fruits. Its really obvious when the fruit is on board. Fruits are wrapped in an elongated three inch sheath, something quasi-similar to a jack-in-the-pulpit arrangement. A very distinctive identifiable trait. No Bluestems look like it. The dwarf strain is obviously different than typical, and everything else around it is of normal height and form. This is obviously a strain that comes true from seed, hence the size of the stand (presently about 30 x 50 feet).

above: Elliot’s Bluestem in fruit, and the dwarf stand, about two feet tall.

Dwarf Indian grass -Indian grass is a great prairie garden plant. It is a runner of sorts, but politely so. Again, like with most native grasses planted in a garden situation with loose soil and no root competition, the height and width can double or more, compared to the normal competitive-prairie size. In the competitive world of the prairie, Indian is polite and docile, and only grows a tuft of grass about a foot or so high, with nearly invisible floral stems to six feet, topped with highly attractive and colorful infloresnces. Yellow Indian grass is the common name for this plant since the flower heads are bright and yellowy, robust and unusually large considering the stem diameter. Indian is highly variable genetically with a variety of genetic strains coming from a handful of seed. Often there are steely blue colorations of foliage and differing leaf forms and sizes.

Dr. Susan Barton, U of Delaware (http://canr.udel.edu/faculty/barton-susan/) has made some wonderful discoveries conduction planting experiments with Indian grass. She told me about how she preps the planting area by spraying herbicide repeatedly and then mixes Indian grass seed with saw dust. Then lays the sawdust-seed mix across the ground an inch thick and voila! Instant Indian grass prairie!!!!!

Dwarf Indian in my seed field -years ago, a friend, Gail Baron (yard flower.com), gave me a few cups of Indian grass with origin, as I recall, from somewhere in Mississippi. I planted it out and it has proven to be a particularly dwarf strain. Nice.

Love grass (there are many species) – Love grass should be a good marketable plant just because of its name. It is a very short-statured grass, much wider than its one foot height. Work should be done on this plant simply because it has such a short overall height. And it comes up readily from seed.

Three Awn grass -Aristidas are feathery, fine textured and rather attractive native grasses that create puffs of color and texture in the landscape. Some come up readily from seed. These are relative to the Wire grass, Aristida strict, so common and dominant in Florida and Georgia pine lands but absent from west Alabama, Mississippi and Louisiana. Generally dwarf in size, most often, about a foot high, wispy and vertical; moved by the slightest breeze. Purty. The best one for horticulture is A. purpurascens.

Narrow Leaf Bluestem – a most promising garden plant and lawn substitute, Schizachyrium tenerum has a short and rounded form with needly-thin leaves, growing about a foot high and 30 inches wide. Its distribution range is a fairly small area, the central  Gulf coast, mainly, with some disjunct populations, east, in eastern Georgia and North Carolina and west to Corpus Christi, Texas. Narrow Leaf Blue is unique in that it is one of the species in the Coastal Prairie of Louisiana (Cajun Prairie) that separates the Tall grass prairie of the midwest from the Tallgrass prairies of the Gulf Coast region. It has something to do with the Gulf influenced coastal pine lands intergrading with the Tallgrass prairie. Its a true Southerner.

Pineland Dropseed, Sporobolus junceus -what a beautiful and very useful grass this plant is! A favorite of mine. It graced my prairie seed catalogue cover years ago. Prairie Dropseed casts a wide net horticulturally for the potential it has for use in gardens, home and urban prairie landscapes and especially for the no-mow or low-mow native lawn. This plant is so petite, a tiny thing, that gets about six or eight inches in height and maybe a little less wide. The inflorescences are erect barely visible, they’re so thin and fine in texture. Very interesting. Its a clumping tuft with fine textured foliage and is delightful to find en masse in the wild. Am presently working on plantings of it for demonstrations for the last couple of years.

Brownseed Paspalum -Brownseed is a great early succession nurse crop for strarting a prairie garden since it comes on early in dominance and stays until competition moves it out to a lesser roll in the prairie landscape. A good wildlife plant but not much on the eyes. Most folks would say it looks like Bahia grass but it is quite different, actually. Much thinner inflorescences and fruit clusters. Its another Gulf coastal species mostly, with reach into northern area outside the coastal plain. Adaptable from Texas to the Carolinas.

Side Oats Gramma (or Side Oats Grammaw grass)– Boutaloua curtipendula isn’t supposed to be in Louisiana but Botanist Chris Reid showed me a killer naturally occurring stand last year in Cameron Parish, a stone’s throw from the Gulf. He and another expert told me that that is an anomaly and that that stand is probably something that came from seed sowed for forage. I dunno. However, its growing like a weed in the Louisiana coastal Parish of Cameron! That’s big news folks. Big potential there in that genetic strain. I went to collect some seed and or plants last year and it had just been nuked by the Highway dept. or county road crews. Bummer, dude. This species (and for us, this strain) has incredible potential for low-mow, no-mow lawns and is a great garden plant. The closest place to find it naturally near us, other than in Cameron Parish stand is in the Black Belt prairie region where it is not common at all, rare. These Black Belt genetics have potential for trial also, in heavier, higher Ph soils like New Orleans and Baton Rouge.

Eastern Gamma –is a big, big plant. Its a large textured, pale green leaved, rounded plant with flower spikes that radiate outwardly and above the foliage in all directions, from the center. An ancient relative of the corn plant, if you suck on the seed a bit, you’ll see it even tastes like corn. Voted a better plant for bio-fuel than Switch because of its higher sugar content, its also an ornamental plant of note. It can be grown easily from seed but is not as fast as say, Switch grass. But in three years time, you can easily grow several acres by seed and save tons of plant costs while creating large swaths of grassy landscape. Super good fire generator and an excellent wildlife food and cover plant. Also, ook into the use of its far-southern first cousin Florida Gamma grass, rare in the wild but common now via conservation, on highways and shopping mall parking lots in south Florida, Miami area. Cool beans. I have a nice stand of about fifty maturing plants in my home garden here in Covington, trying it out. It seems to be tough as its cousin for me so far.

Go! Micro-Prairies!!!!!

 

 

Monty the Dog Goes to the Farm!/ awesome new LSU Hilltop meadow planting-planning/ City of Mandeville-La DOT pine prairie planting completed/LSU Hilltop Arbo Symposium speakers finalized, announced

 

IMG_9424

Monty the Wonderdog, captured in digital form, on his way to the seed farm in Mississippi the other day. Monty likes fetching sticks and smelling-out deer and other wild critters in the native grass fields. Most of all, though, he likes to stick his head out of the window to get a sense of the neighborhoods along the route. That’s what he’s best at, plus the fact that he’s a certified therapy dog and all. He’s not an amateur dog, he’s a professional! He was pleased with the day overall, he said.   (click on the pic and see him up close. He’s funny.)

I just got the notice for details for speakers for the Hilltop Arboretum’s winter Symposium and what a great line-up it is. I will, of course, be speaking on grass landscapes (duh) for the home garden and the urban environment. The symposium is geared to gardens and garden plants rather than ecological landscapes. It sounds like it will be a fun time with a speaker’s get-together the night before, so I’ll be able to catch up with a few folks I haven’t seen in many years and some I’ve never met. here is the link to the Hilltop Symposium announcement. There’ll be more info coming soon, I’m sure.

Yesterday, Doug Reed was in Baton Rouge to discuss the new prairie natural area being designed for the Hilltop Arboretum. Doug is an nationally recognized landscape designer, an LSU grad, principal partner in the firm Reed-Hilderbrand, LLC, of Cambridge, Massachusetts. Doug and I collaborated 3 years ago on the initial design phase of the Hilltop prairie when it was just an idea and we worked together on the super-sleek Repentance Park project in Baton Rouge shortly after that. I hear that I will likely be involved in the final horticultural details and if I get lucky, provide the seed for the actual plantings once the construction of the prairie meadows begin. I was invited to be present at Doug’s presentation to the Hilltop board of directors but am too busy with planting right now to pick my head up. Gotta make hay while the sun shines. Peggy Davis, the Director at Hilltop, organized a field trip to Crosby Arboretum and to my seed farm last summer to get a hands-on feel for what a real restored prairie is. A bus load of people connected to Hilltop visited and walked the Meadowmakers prairie paths. They must have liked what they saw since the project to create real biodiversity via constructed natural areas of meadows is still on! whoot!

Once completed, this planting will provide an outdoor classroom and research area for landscape design and biology students right in the heart of Baton Rouge.

The City of Mandeville’s wildflower conservation planting has been completed as of last Friday. I met with the very capable Herb Piller, a landscape designer with Louisiana Department of Transportation that day. He was interested in the planting process and took a few photos, asked a few questions.

All complete and ready for seed to stratify! I will be managing these gardens for two years as part of the installation contract. Really nice Long Leaf pines from Louisiana Growers! go Rick!

The burn team got together and did some controlled burning at the seed farm in Mississippi yesterday. It was perfect conditions for a wild fire and thanks to our dedicated volunteers, we got two major sections done without burning the neighborhood down. These were two areas, about four acres altogether, with two years of fuel built-up and the humidity was really high with lots of grass present so we had some really spectacular visuals and adrenaline rushes from the leaping, flaming vegetation. Lots of poppin’ and crackin’ in the low, wet areas between the hill slopes. It was quite the event, ya’ll (don’t try this at home kids)!

Mandeville’s new 1 acre Long Leaf Pine prairie preserve

Thanks to the forward thinkers at Mandeville City Hall and the Mandeville City Planning staff, the one acre island created (two islands, actually) by the roadway intersection at Highway 190 and the east Lake Ponchartrain Causeway approach will soon be completed. The planting is inspired by the Long Leaf pine prairies that were once so prevalent in the Parish and the entire Central Gulf Coastal region. Tim Bailey, a local landscape contractor and Prairie Dog, Inc. (Pastorek Habitats, LLC.), have been chosen to collaborate on the planting and management of the project. The planting is just east of the Causeway approach, check out the google maps to locate. You may have to click and enlarge the photos below, to see.

mandeville pine prairiemandeville

I’ve worked this past spring and summer, getting the prep work done and Tim has just completed the tree plantings; a few Live Oaks located in the outside of the pine prairie and Long Leaf Pine and Cherry Bark Oaks, chosen specifically because they would be a natural companion for the prairie and because they are pyrogenic (they love fire!). The plan is to use annual controlled burns as the preserve’s main management device.

Adam Perkins, a Landscape Architect based in Hammond (Dufreche and Perkins), and Maggie Gleason, Landscape-Urban Forestry Inspector for the City of Mandeville’s Planning Department collaborated on the planning and design of the landscape. Adam, Tim and I all worked together at Chapapeela Park prairie landscape in Hammond, which is a jewel in the crown of Hammond’s public Park system. Adam’s graphics are great. They explain the project very well.

Gotta give credit to Chuck Allen and Mac Vidrine, those crazy-brilliant-Cajun-Prairie-cats, because without the help of the how-to science they developed, the preserve would probably have become a large tree filled lawn that would have to be mowed in perpetuity, or something really boring like that. By approaching the “approach” this way, we get awesome wildflower diversity and eventually, fire on the ground!!! We also get another model of what can be done in the urban context with ecological landscaping; totally logical.

Signs identify the pine prairie area as “wildflower preserve”, a series of posts delineate the prairie from mowed turf for maintenance staff when they are mowing and to create a neat strip of highly managed vegetation that will contrast beautifully with the wildness of the blanket of prairie. Caroline Dorman, Louisiana’s pioneering promoter of “the wild things” would be proud!

MODEL - SCENE 8

This is a big deal for Mandeville, ya’ll. And for us, too! . And for Pine prairie!!! We will be planting the first week of December and I hear that the local Louisiana DOT representative and some other City leaders want to be present at some point when we are seeding to see what we do and how we do it. There seems to be a lot of interest in this project. The City Leaders seem invested in more ways than one. Will keep you (all three of you) posted on progress, as it happens.

cool, useful plants, and cool, useful insects

Our old farm land in south Mississippi, in the last sixty years, had been dozed and then terraced, planted with Tung oil trees (in the 1950’s), cleared for cow pasture (in the 1970’s) and then attempt-restored with native wildflower and grasses (in the 1990’s). One of the most abundant plants on the property is one I didn’t plant, the somewhat common Willow Leaf Aster, Aster prealtus. Its a dog-gone pretty thing, with lavender flowers on terminal tips and blooms the third week of October. What I heard from Dr. Malcolm Vidrine recently is that it is one of the most important plants for Monarchs on their migration south on their way to winter in Mexico. Malcolm’s comment stuck with me and gave me a new perspective on what I thought was kind of a weedy plant. I was at the farm yesterday and got to see my fields of Willow Leaf Aster in blazing glory. Its a disturbance oriented plant, it seems, found where some sort of soil activity has occurred. That’s why Aster prealtus is so important, since much of our land these days has been disturbed one way or another and many of the high-end nectar plants are simply gone. Aster prealtus and some others make up for that to some degree.

Also, this week, I found for the first time, a very happy, Late Purple Aster, Aster patens, growing in a planting I planted 13 years ago this month, at the farm. Whoa! …a new species for the farm! Nice…..   Maybe I just hadn’t noticed it before since a I found a few more just after finding the first.

Aster georgia 028a Aster_patens_leaves_resized

Aster patens is a very nice garden plant, a high conservatism species, a 9 on C of C. Tiny flowers and, a delicate thing. Notice how the leaves are wrapped around the stem, a tell-tail ID trait that separates it from many.

I took this picture of a very contemplative Monty the Dog, posing next to a short, rounded Rice Button Aster plant and he took this one of me, next to a wily, gigantic Rice Button, at the edge of the pond. Both of these plants showed up as seedlings and were then left to grow.

above: This is the most-endearing Aster pratensis, growing with Swamp Sunflower, Narrow Leaf Mountain Mint and Little Bluestem grass Cajun Prairie Society Restoration Project, Eunice. A. pratensis and A. concolor are nearly identical, Charles Allen says. Pratensis is to the west of the Mississippi and concolor is to the east. This is a stunningly beautiful flower, big (a little smaller than or about the size of a silver dollar) and a good Mardi Gras color purple, found in high quality late succession natural areas. These would maybe never be considered a marketable ornamental plant because the plant is usually a leaning stalk with a flower or three at the tip. But it seems it could be a parent for horticultural breeding program, huh?

above: Jim Foret checking the bee hive at the edge of Charles Allen’s butterfly-bee garden, October 8, 2014, Pitkin, Louisiana. Jim donated the hive to Charles’ bee cause. It was a hive of Jim’s friend who thought it was too heavy to work. Jim packed it into his truck one night last spring and drove it up to Vernon Parish to Charles’. He was checking out the interior bee goings-on before winter to see how they were set up with honey. Go Jim!

Along with butterflies and skippers, native bees and the old world honey bees, wasps are also huge fans of Asters. Have asters and have a host of good insect species that will utilize them. Fun stuff.

I am so darned excited about an upcoming building project I can’t stand it!  …my Kenyan salt pond top-bar bee hive construction project. Jim Foret recommended me looking into it since I told him I wanted to have a working hive around but I didn’t want to work the hive much. I searched Kenyan Top Bar and saw a youtube of U.S. Peace Corps youngsters filming a few guys constructing one in Guinea, Africa. check out how easy it is to build and then find a youtube that demonstrates harvesting the honey and comb. It is so complex, the hive workings, but so simple it seems, to build the hive!

Also, check out a recent paper (2004) by Chandra Sara Bartholomew on native bees done at Abita (TNC), Sandy Hollow (USF&W), and Camp Whispering Pines, in the Florida Parishes.   ….excellent paper, excellent insight and has everything to do with native bees.

Iberia Parish’s Matt Conn makes New York Times with his wetland restoration project + 120 acres, dripping, oozing in wondrous herbicidedness + a holy-cow prairie remnant!!!

I was treated to the wondrous sight Tuesday of the project property where the mother load, 700 pounds, of wet-coastal prairie seed, seed that I have been collecting this summer, will be planted. The vegetation was nice and toasty brown, the color of awesome death. Yummy!! Boy did this make me (and my seed) happy. 🙂

After all, why would anyone work so hard and stake so much investment in money, seed and time only to see in three or so years that it all was wasted because the right prep work wasn’t done? I would rather see the weedy vegetation totally-wasted, and my seed, so precious and rare, and so hard to acquire, given a proper chance for survival. No, this seed deserves an opportunity for a long and healthy life.

IMG_7451

IMG_7463

above, looking north ……and into the bright future…

After the visit to the planting site, I was then lead by a good friend and mentor across the creek (the Calcasieu River) to see what he said was definitively “the most significant coastal prairie site in the state”. This coming from a fellow who at his early age, has just about seen it all. Pretty sure he was right with that claim, after seeing it with my own eyes. It was an old cattle farm property that had never been plowed, complete with monstrous pimple mounds, low prairie, and an occasional marias, all filled with premier prairie vegetation and very little, almost no, foreign invaders. On the pimple mounds were the high and dry species, some common in the Looziana sandy piney woods. At the base of and surrounding the mounds were the heavy-soil low-land species. And in the marias were the marginal aquatic and aquatic species, all thick like hair on a dog’s back. We walked through dense vegetation. We worked for our reward since it was a good, hot day albeit a bit over cast and a long way to go. We made a large loop with many smaller dipseydoodle-loops through what I’m guessing was about ten to fifteen acres or more of land and saw only a small portion of what was there to be seen. When we were done, we were both dripping wet, soaked to our boots. Had a good work-out/ detox! Spent over two hours ooh-ing and ah-ing. I am not sure who was more excited, he or I. In April, he and his colleagues had used fire in the way of controlled burn, to breathe new life into this amazingly diverse prairie remnant, something it had not seen for many many years.

This is a highly significant plant, attractive to numerous nectaring insects. This patch was about two acres in size. Woah! We were both likes little kids in a candy store. We didn’t know what to do with ourselves. We had found heaven on Earth.

The wonders of Lance-leaf Blanket Flower

I walked with a client the other day in a field planted last winter with a Long Leaf pine herbaceous understory wildflower seed mix. It was a great walk and we got to see about a dozen species of high conservatism, juvenile in stature. Some though, had flowers and for me, that is always exciting. Not too shabby for a first year walk. 🙂

One of the plants we happened upon was Gailardia aesivalis, the Lanceleaf Blanketflower, some folks call it Yellow Indian Blanket. This is not to be confused with the more coastal and gaudi-colored Indian Blanket Gailardia pulchella. These are plants worlds apart, in my mind.

gaillardia_pulchella_020207_1

What do you do with the orangey red and bright yellow of Indian Blanket? umm, Not much when you’re a plant snob like me…

Gaillardia_aestivalis_7659_800

This, my friend, is a classy gal, the most common form of Yellow Indian Blanket or Lanceleaf Blanket Flower, Gailardia aestivalis variety aestivalis. If you’re lucky, you have her growing out in the back forty or right at the front door.

2122069

above: a more rare sub-species for Louisiana (and elsewhere) is Gailardia aestivalis variety flavovirens, the Yellow Indian Blanket with an obvious and pronounced yellow central disc. This is found in Vernon Parish and Allen Parish, also in the Kieffer prairies, and in some Parishes in upper-central Loosianna. Quite a find indeed.

The common Lanceleaf Blanket Flower is a most desirable plant to have in the garden or the natural meadow. It happens to be a very long blooming, one I consider to be the longest blooming of all of our native wildflowers. It also has the characteristic of dropping its petals and holding the rounded, maroon-wine colored central disc, which is very ornamental itself and persists for a long while until seed is fully formed. It is extremely adaptable to a variety of soils. In Louisiana, you’ll find it in the Cajun Prairie, the piney woods, the clay of Kieffer prairies, Copenhagen prairie: an amazingly adaptable thing it is. Just give it a full day of sunlight, step on it every now and then and if you can, burn it. Its a pyrogenic plant. It loves to go up in flames!

It is a significant nectar plant for numerous butterflies, skippers, and other beneficial insects. And because of that, it is popular for predators, who hang out in wait for the nectaring tribes to come moseying along.

This plant maybe wouldn’t make it in the dog eat dog world of horticulture, but for the work of the good folks at the Steven F Austin University Horticulture Department and its associated Piney Woods Native Plant Center. This is due mostly to the keen eyes of the amazing forth-degree master, Dr. David Creech and his black-belt side-kick, Greg Grant.

Dr. Creech and Mr. Grant have been working with a rare species of Blanket flower, Gailardia aesitvalis variety winkleri, a wonderfully clear white variation found only in a few counties along the Texas Coastal prairie. What a fabulous thing it is for them to have found this plant! From their selection work, they have produced a significant horticultural introduction, a cultivar called Grape Sensation.

About fifteen years ago, I introduced one of the first passalong plants of winkleri from Dr. Creech via Peter Loos, into my meadow field in Mississippi. I forget now what color form it actually was that I was given. But today you can walk through the area where that plant was planted and see a whole variety of color forms, plants that seeded since, parented from the original. There’s white, pale lavender, darker lavender, deep redish, and so on, so forth. Its a wonderful experience if I say so myself. Come see them when you can. And get some Lanceleaf Blanket Flower! Find it at the upcoming plant sale at Steven F Austin or at specialty nurseries like Tony Avent’s Plant Delights nursery, through mail order.

peace!

central Gulf South Silphiums

Rosin Weeds are not weeds at all. They are really fine ornamental herbs that provide for substantial wildlife activity and add lots of pizzaz to a garden. Silphiums are some of the more shining, luminous jewels you can incorporated into your prairie-meadow if you’ve got one. Several Silphium species are native to our region and all are easily grown, adaptable, dependable, and extremely persistent garden plants. That is, if you can find them in the nursery trade available for purchase or …if can get some seed. Most all of mine were originally grown from seed.

Silphiums are no minor player when it comes to garden boldness. My friend Gail calls them “tall boys”, and puts them in the same category as Joe Pye Weed, Iron Weed and Big Bluestem. All are adaptable, long to establish but long-lived, and permanent plants that almost never need care.

They’re exquisitely beautiful organisms. Excellent garden plants, no doubt. They have a huge capacity in the landscape for specialized ecological function. They feed good-weird bugs and stuff (they’re highly attractive to butterflies and other very specialized pollinators, y’all).

I’ve heard some of my northern gardener-friends say that they are weedy, but I have not had that kind of luck yet. In the fifteen years or more I’ve grown Silphiums, I have never had enough show up via re-seeding and they have rarely become prolific in a planting, only somewhat, maybe. But they seem to be more than prolific above the Mason-Dixon line. Dumb luck, I guess.

Rosinweeds are for royalty. They are for refined gardens and wildscapes, too! They are horticultural clout. Vertical botanical bling! Some of Europe’s most visited gardens have American Silphiums in them. The Brits Dunnett and Hitchmough use them in their famous wildflower work. And where we live they are tame, yet seductive.

Most Silphiums grow as large-leaved herbaceous plants, big leafy rosettes with tall terminal stalks laden up-top with big butter-yellow ‘ray and disk’ flowers. In the best conditions, during the best year for rain, the tallest ones, the Compass Plant and Prairie Dock, both can grow flower stalks to eight or ten feet tall.

Who wants an eight foot tall herb in their garden? Me, that’s who!!!!

Actually, Rosinweeds are just foliage clumps in the landscape for months in the spring and early summer until the plant prepares to bloom, sending stalks skyward. The photo above,(click it to enlarge it) taken by Jovonn Hill, of the Pulliam prairie landscape in Chickasaw County, Mississippi, with Prairie Dock, Silphium terebinthinaceum, just emerging in April, after a controlled burn. Cool thing is you can see right through the stalks of Silphiums when they bloom, like, the stalks almost become invisible.

Here are the Silphiums I have grown for some years now, in my gardens.

SIGR4-1

S. gracile or Slender Rosin Weed’s distribution range, above, a plant found both in Pine forests and Prairies in Louisiana. Lush rosettes, entire leaves, high-oil seed makes for an excellent wildlife plant. Gracile is a real southerner with a red-neck attitude, often kind of slouchy and grinning. No, really, its a very plant with a good attitude. Niche Gardens, a specialty native plant nursery in Chapel Hill, N.C offers this species for sale.

S. simpsonii, Simpson’s or Tall Rosin Weed is a non-Louisiana Native given to me by Texan nurseryman Peter Loos in the mid 1990’s. Good-naturalizing, adaptable, seed excellent for wildlife. Looks very similar to gracile.

S. integrifolium, Prairie Rosin Weed, is found associated with inland prairies of Louisiana and the Jackson Belt prairies of Mississippi. Its a Rosin Weed with conspicuous leaf arrangement. A vertically attractive course-textured plant.

S. terebinthinaceum, Prairie Rosin Weed (above), is not found naturally occurring in Louisiana and is only found in one county in Mississippi and one in Alabama. Its at the southern end of its range here in the GS. The largest leafed Silphium, by far. Awesome. Tony Avant of Plant Delights nursery in Chapel Hill grows and offers it for sale. Mine hasn’t bloomed yet and it is at least five years old but the leaves are very large and showy without flowers. It may have a lot to do with the seed coming from clay-specific soils to acid soils here in Covington, duh.

IMG_4820

above: S. perfoliatum, The Cup Plant, is an uncommon plant in Louisiana, with records in only one Parish. More commonly found in much of the eastern U.S (minus Texas), this guy has the distinction of forming “cups”, where water collects where the ‘perforated’ leaves join the stem. Bold and strongly structural architecture.

S. asteriscus, Starry Rosin Weed, is one I have only grown for four or five years now. It seems to be very floriferous and a bit shorter than most other species.

Silphium (origin, Will Fleming) is a curly margined form of a yet-unidentified (um, I forget) species with a distinctive leaf form. I’ve grown this plant for five or so years. A worthy ornamental.

Propagation of these species is fairly easy if you have some good, viable seed. Just sow the seed in a good soil mix and barely cover the seed, enough to keep it moist. Germination will come pretty quickly unless its the dead of winter. Field grown Silphium seed is a horse of a different color. Seed I sowed of laciniata, in 1998 and 99 didn’t show up for several years, being out-competed and beat-up by unwanted competition. So eliminate competition in the field before sowing and maybe save yourself some years of waiting and wondering.
