Dense blazingstar and Indian plantain in the Cajun Prairie Restoration Project in Eunice in 2013.

Several species begin reaching for 7-8 feet and will probably achieve 9-10 feet by the end of the season. On the first of August in 2015, Big bluestem was already 7 feet tall. Big grasses reach heights of 8 feet and sometimes up to 10 feet.

Esterwood prairie remnant in the early morning (August 1, 1989) with tall stands of Compass plant, Dense blazingstars and Rattlesnake master. This is my most memorable view of the remnant prairies.


The month begins with a splash of Liatris spicata (Dense blazingstar), Arnoglossum ovatum (Indian plantain), and Silphium laciniatum (Compass plant). Eryngium yuccifolium (Rattlesnake master) and Helianthus mollis (Ashy sunflower) continue to bloom and dominate views. The sunflower family reigns for the next 3 months. August begins looking a lot like the end of July, and it ends with the expectation of a massive bloom of Liatris pycnostachya (Kansas gayfeather or Blazingstar)).

Rhexia mariana (Maryland meadowbeauty) has been blooming since the end of May, but its pink blooms are now abundant in wet prairies. Hydrolea ovata (Blue waterleaf), Vernonia gigantea (Giant ironweed) and Ipomoea sagittata (Salt-marsh morning-glory) are also common in wet areas.

A plant has to be large/tall to stand out among the myriad large grasses that begin taken over the scene. The grasses include Big bluestem, Little bluestem, Yellow Indian grass, Switchgrass, Eastern gamagrass, Florida paspalum, and many others. Corepsis tripteris (Tall tickseed), Rudbeckia subtomentosa (Sweet black-eyed susans), Monarda punctata (Spotted beebalm), Salvia azurea (Blue sage), Physostegia praemorsa (Obedient plant), and Pycnanthemum albescens (White-leaf mountain mint) start to put on a show.

Gaura parviflora (Long-flowered beeblossum) is 7-8 feet tall with tiny beeblossum blooms. Manfreda virginica (American aloe agave) stands 5-8 feet and has small flowers lacking sepals and petals; however, it has aloe agave-like leaves that often have spots. Desmodium spp. (Beggar’s ticks or lice), a very tall pea plant with small pea flowers, blooms here and there—these plants produce seed that stick tightly to clothes as one walks through the prairie in September and October.

Three views of Wild coco orchids from the Kinder and South Fenton prairie remnants.


Pteroglossapsis ecristata (Wild coco orchid) blooms. This orchid was not common in the remnant prairies, but several specimens have survived in the Cajun Prairie Restoration Project in Eunice. During the 1980s, Charles Allen could spot these inconspicuous blooms, whereas I could not. Populations of this orchid persist in Kisatchie National Forest and on Fort Polk, but it is not likely surviving on the remnant prairies. Two color varieties, purple and yellow blooms, co-occurred in the remnant prairies.

August is hot, but some mornings and late afternoons are bearable. In the gardens, butterflies finally start to really increase in numbers. The most common species are Gulf fritillaries and Buckeye butterflies—caterpillars of the former feed on Passionvine (Passiflora spp.), while caterpillars of the latter feed on False foxgloves (Agalinis spp.).
