The genus Asclepias (milkweeds) include mostly native perennial herbaceous species in the Asclepiadaceae and is a Dicot.  All species have milky sap except for butterfly milkweed (A. tuberosa).  The leaves are simple, entire, pinnately veined and mostly opposite but whorled or alternate to subopposite in some species.  The inflorescences are umbels that are cymosely or corymbosely arranged.   The flowers are perfect, regular, and with five sepals, petals, and stamens.  The petals are usually strongly reflexed and the five filaments are modified into five hoods that form a corona round the ovary.   Most species also have horns on the corona.  The pollen is produced in pollinia with each pollinium formed of two pollen

masses from adjacent anthers.  The ovary is superior with two carpels and the fruit is a follicle with distinctly comose flattened seeds.  This is a large genus with more than twenty species reported for the state.  The common species with white or green flowers include longleaf milkweed (A. longifolia), Michaux’s milkweed (A. michauxii), pineland

Asclepias obovata

nillkweed (A. obovata), white milkweed (A. variegata), whorled milkweed (A. verticillata), green comet milkweed (A. viridiflora), and green milkweed (A. viridis).  Two species, swamp milkweed or aquatic milkweed (A. perennis) and common milkweed (A. syriaca) have flowers that range from white to pink.   The species with pink, rose, purple, red or yellow flowers include clasping milkweed (A.

Asclepias purpurascens

amplexicaulis), Brazilian milkweed (A. curassavica), pinewoods milkweed (A. humistrata), swamp milkweed (A. incarnata), fewflower milkweed (A. lanceolata), purple milkweed (A. purpurascens), red milkweed (A. rubra), and butterfly milkweed (A. tuberosa).  Three of the white to green flowered milkweeds (longleaf, Michaux’s, and whorled) have linear leaves that are more than ten times as long as wide.  Whorled milkweed has whorled leaves while the other two have opposite to subopposite leaves.  Michaux’s milkweed has a solitary umbel and a corona that is more than 5 mm across while longleaf milkweed has two to five umbels and a corona that is less than 5 mm across.  Whorled milkweed is a prairie and open pine forest species that is scattered across the state with reports from 25 parishes.  Longleaf milkweed is a bog and pine savannah species with reports from 19 parishes and Michaux’s milkweed is a pine savannah species and is only known from St. Tammany, Tangipahoa, and Washington parishes.  The other white to green flowered species all have lanceolate to ovate leaves that are less than ten times as long as wide.  These include pineland and green comet milkweed with sessile to subsessile inflorescences and white milkweed and green milkweed with pedunculate inflorescences.  Pineland milkweed has a corona that is more than 5 mm across while the corona in green comet milkweed is less than 3 mm in diameter.  Both are common species of open pine forests and the Cajun Prairie with reports from 19 parishes for pineland milkweed and 17 for green comet milkweed.  White milkweed has pure white flowers, is an erect plant, and is found in shaded hardwood forests while green milkweed is a spreading plant with green flowers and is usually seen in open areas, especially prairies.  White milkweed is reported from 36 parishes and green milkweed from 34.  The two species with white to pink flowers (A. perennis and A. syriaca) also have lanceolate to ovate leaves and pedunculate inflorescences.  The differences between the two species is that A. perennis has pedicels that are shorter than 3 cm and coronas that are narrower than 3 mm while in A. syriaca, the pedicels are longer than 3 cm and the coronas narrower than 3 mm.  The habitat and distribution are also different with A. perennis inhabiting wet areas such as swamps and wet roadside ditches throughout the state in probably all parishes with current reports from 56 parishes while A. syriaca is a plant of disturbed areas in Lincoln, Morehouse, and Ouachita parishes.  The most distinctive of the pink, rose, purple, red or yellow flowered milkweeds is butterfly milkweed (A. tuberosa) with alternate leaves and non-milky sap.  It is widespread in the pine and prairie regions of the state with reports from 34 parishes.  All the other species with these color of flowers have opposite leaves and include fewflower milkweed (A. lanceolata) with linear to narrowly lanceolate leaves.  It is an infrequent plant of wet areas mainly in the prairie and pine flatwoods portion of the state with reports from 12 parishes.  Both clasping milkweed (A. amplexicaluis) and pinewoods milkweed (A. humistrata) have sessile clasping leaves.  Clasping milkweed is widespread in dry sandy soil with reports from 25 parishes while pinewoods milkweed is known only from St. Tammany and Washington parishes.  Clasping milkweed is an erect plant with a solitary terminal umbel and corona that is 5 mm or wider while pinewoods milkweed is a spreading plant with two to five umbels, and a corona that is narrower than 5 mm.   Both Brazilian milkweed (A. curassavica) and red milkweed (A. rubra) have glabrous to sparsely pubescent leaves while swamp milkweed (A. incarnata) and purple milkweed (A. purpurascens) have pubescent leaves.  Brazilian milkweed has red to yellow flowers and is a cultivated plant that persists in southern Louisiana but takes on an annual habit in north Louisiana.  Red milkweed has pink flowers and is an infrequent plant of baygalls and bogs in west central Louisiana with reports from Beauregard, Natchitoches, Rapides, and Vernon parishes.   Swamp milkweed (A. incarnata) has lanceolate leaves and is a plant of the marsh with reports from Jefferson, LaFourche, St. Charles, and Terrebonne parishes while purple milkweed has ovate leaves and habits well-drained forests in Caldwell and Lincoln parishes.

 

Two decades of growing milkweeds from seeds collected in the Cajun Prairie have met with good success. Numerous failures are attributed to weather, poor container choice, lack of cold moist stratification (CMS), seed inviability (not uncommon during years with few pollinators), and poor site selection for placement in final growing site. I plan to focus on successes rather than failures, but the failures not only punctuate but also clarify the successes.

Asclepias tuberosa (Butterflyweed), A. lanceolata (Red milkweed or Few-flowered milkweed), A. viridis (Green antelopehorn), A. perennis (Shore milkweed or Swamp milkweed), and A. verticillata (Whorled milkweed) were my central focus. Numerous experiments involving seeding in a variety of soils both in containers and interseeded directly into the prairie soils gave poor if any success. Recent experiments employing CMS have changed these results dramatically. I have literally given up on planting seeds directly into the prairie restorations.

Here is my strategy:

  1. Collect seeds from locations near the final growing site. For years I collected and/or bought seeds of a variety of milkweeds, especially Butterflyweed, from numerous places in Louisiana and other states—these grew and bloomed (or not) as annuals only to die in the moist winter soils of the Cajun Prairie. The Cajun Prairie Butterflyweed that I grow was found just south of Eunice in a woodland meadow along a railroad right-of-way—they and their offspring have grown in my gardens for up to 17 years.
  2. Remove the seeds from the follicles when the follicles split with a little pressure from your fingers. Grasp the silk and pull the seed from their silks. Seeds should have a viable embryo—a nut-like palpable swelling.

 

  1. Store the seeds in a cool, dry place until February.
  2. In February, place the seeds into CMS. This simply requires placing the seeds in a Ziploc-like bag with a small amount of damp sand for 6 weeks in the refrigerator. Do not do this to the non-native Mexican milkweed (A. curassavica)—the CMS is lethal in my experience—plant these seeds directly.
  3. In March-April, add water to Ziploc-like bag, and the viable seed should float to the surface. Remove the seeds into a growing chamber—I use plastic containers that come with a lid. The seeds are spread out on the surface of potting soil—almost any kind works—and a light covering of soil is used to simply hide the seed. Keep the chamber closed and moist. I place the chamber in a south-facing window.
  4. Seeds germinate in a week—really germinate—hundreds of them. Allow them to grow out a second pair of leaves—usually 2 weeks.
  5. Move the seedlings outside and transplant them into large containers—5 gallon containers for 1-2 years. I prefer 2 years in order to allow the roots to grow really large (several inches long) and easy to handle.
  6. In winter or early spring, either transplant the entire container into the ground or remove the roots and transplant them separately into the final growing site. The roots can be divided in the spring into 2 inch segments, and placed in individual containers providing even more plants. These cuttings can also be planted into the final growing site with approximately 50% success. As a final propagation note, all species can be grown from stem cuttings (taken after Monarchs are done eating), but the success rate is highly variable, and the process requires more intensive work.

General notes:

  • Butterflyweed—it is essential to grow plants from near your location, and it takes years to get a specimen plant; thus plant 3 in a triangle about a foot apart. The plants reach 3 feet in height and have red to orange flowers.
  • Red milkweed or Few-flowered milkweed—while this plant likes damp soils, it readily conforms to good soil, but it cannot tolerate drought. I have lost hundreds of these from planting them in poor, dry sites or to severe droughts. The plants grow 4-5 feet in height and have yellow to red flowers.
  • Green antelopehorn—this plant can be grown in your lawn as it actually appears to appreciate being mowed by machines and/or Monarchs.  It is very easy to grow compared to the previous 2 species. The plants grow to 2 feet high and have green flowers.
  • Shore milkweed or Swamp milkweed—this plant can tolerate container growth for years, unlike the 3 previous species. It prefers damp soils and cannot tolerate drought. It stays green almost all winter, and it is a superb host for Monarchs as it is green both in early spring and in late autumn. It is the easiest to grow, and the most prolific bloomer. Seeds lack silk. The plants grow to 2 feet high and have pink or white flowers.
  • Whorled milkweed—this plant is easy to grow and transplant. It prefers damp soils and can tolerate drought better than the red milkweed. The plants grow to 3-5 feet and have green to white flowers.

All of these are used by our migratory Monarchs. Each has different growth habits and requirements for good flowering. Butterflyweed and Whorled milkweeds appear to be long-lived (more than 10 years), while the other 3 species appear shorter- lived (usually more than 5 but less than 10 years).

 

 

 

 

 

A thesaurus lists synonyms for harbinger as forerunner, herald, portent, omen, and indication.  A harbinger has to occur in a designated time period before the event.  So a harbinger of spring would have to occur in our area in January or February and March in North Louisiana.  It has been my observation and was pointed out to me by my teachers that there is about a week difference between the beginning of spring in New Orleans and Shreveport, about 300 miles north-south.  One of the items on my “bucket list” is to follow spring north one year.  I would drive to south Texas in early February and then drive slowly northward following spring.  I would zig and zag across Texas and Louisiana and move about 300 miles north each week.  Then on thru Oklahoma, Kansas, etc until I followed spring all the way into Canada..

But, I am off topic; back to harbinger of spring.  I first heard a botanical use of harbinger of spring in reference to the Trillium which also has the common name of “Wake Robin” in the northern United States.  I had to think about that for a while and realized that when the Trilliums begin to flower here, we should call it goodbye robin.  There is a plant of the central and northern US that has the common name of “Harbinger of Spring”.   It is a member of the mustard family with the scientific name of Erigenia bulbosa.  In Louisiana, we have some closely related species that are usually called spring cress (Cardamine hirsuta) and another one called bulbous spring cress (Cardamine bulbosa).   Both are harbingers of spring with spring cress found across the state and bulbous spring cress mostly in central and northern Louisiana.

In southern Louisiana, the best harbinger of spring is yellow top or yellow sneezeweed (Senecio glabellus).  In January every year, you can see this plant covering many of the wet roadside ditches from Lafayette to Baton Rouge and to New Orleans.  It is so common that a new common name has been created “ditch daisy”.  Another harbinger of spring in not only south Louisiana but throughout the state is the yellow flowered crowfoot (Ranunculus).  It often dominates in pastures where the cows won’t eat it.   Some other harbingers across the state are annual bluegrass (Poa annua), bluets (Houstonia), henbit and (Lamium amplexicaule).  The tree that so many people notice and is their harbinger of spring is red maple (Acer rubrum).  Its red flowers attract a lot of attention in January and February each year. pastedGraphic_4.pdf

In yards and other planted areas, bridal wreath or snowflake (Spiraea), Japanese magnolia, and daffodils (Narcissus) alert you to the coming of spring.  I can remember my mother looking out of the house and saying “look at the snowflake”.  My younger nephew jumped up and ran to the door thinking he would see snow but was very disappointed.

As you move to the central and northern parts of Louisiana, other harbingers of spring can be seen.  The shrub Elliott’s blueberry or summer huckleberry (Vaccinium elliottii) produces its small white flowers that will later become wonderful tasting summer huckleberries.  And, if you look closely in the shaded forest, you might find these orchids, twayblade (Listera australis) or spring coral root (Corallorhiza wisteriana).   As mentioned earlier, Trillium is one of my earliest harbinger of spring and still gives me a thrill when I see my first Trillium for the year.  Most of our Trilliums have greenish to maroon petals but in extreme northwest Louisiana, there is a species of Trillium with small white flowers.  A widely distributed woody plant in the state is the native bamboo or sometimes called river cane (Arundinaria gigantea).  Not many people have ever seen it flower for two reasons; (1) it rarely flowers and (2) the flowers are very bland and not noticeable.   I am in the woods a lot during the year and see many populations of the native bamboo but usually only find one or some years no population in flower per year.   A woody vine with wonderfully smelling yellow flowers is yellow Jasmine (Gelsemium sempervirens).  It is a very common vine throughout the pine regions of the state.

In north Louisiana, bloodroot (Sanguinaria canadensis) is a sign of spring on the way that is not found in south Louisiana.  Its name comes from the red underground rhizome.   Spring beauty (Claytonia virginica) has large edible black bulbs and produce white to pink flower to signal the coming of spring.  It is mostly a plant of north Louisiana and I have seen lawns of it in Monroe that look like snow is covering the ground.   One of the most interesting harbingers of spring are the dogtooth violets also called trout lilies.   The two species (Erythronium albidum and Erythronium rostratum) are restricted to the northwestern part of the state.chamber

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.

Meeting, Sat May 10, 2014

A lot has happened since our meeting in August of 2013.  Just a reminder, that the next meeting is scheduled for Saturday May 10, 2014.  The schedule for that meeting can be found also in this newsletter.  It is the same basic schedule that we have followed for several years.  We will begin at Duralde at 8 am and then migrate to Eunice and then to Rocky’s for lunch, a presentation, and the Society’s meeting.  Please send suggestions for a speaker ASAP.

Eunice Update

Lots of woody invasives were taken out during the workday on Sat Feb 8, 2014.  A dozen, yes a dozen as in twelve, eager volunteers showed up with saws, loppers, and hatchets in hand and herbicide in sprayers.  The woody invasives did not have a chance and are now on their way to the happy hunting grounds for plants, if there is such a place.

Duralde update

On Sat Nov 16, 2013, a group of hardy people showed up at Duralde with the objective of marking off the demo plots with pipes.  The pipes had been purchased by Charles Allen and with the help of Jacob Delahoussaye, had been cut into 4 foot sections.  Using string, the group layed out the plots and then drove poles into the ground to mark the corners of the plots and the mowing trails.  A t-post driver was used which apparently has other names like mother-in-law and the enforcer and perhaps even others.   Five additional plots were tilled and planted.

Charles Allen and Stacy Huskins met with Wayne Syron and Richard Myers of Lacassine Wildlife Refuge on Friday Feb 7, 2014.  Accomplishments at Duralde during 2013 were discussed plus projections for activities in 2014.  The big news was that there is a possibility that Lacassine Wildlife Refuge could (note the word could, so it is not definite) transfer the title of the Duralde Property to another entity.  Also, the possibility of burning of Duralde seems very unlikely. And, Wayne Syron will be retiring from the US Fish and Wildlife Service in May.  He has been very helpful to the Society and we need to recognize him in some way.  Perhaps, a plaque would be appropriate, thanking him for the assistance over the years.
