Taxonomic Notes
Varieties: D. paniculatum var. paniculatum; D. paniculatum var. epetiolatum[1][3]
Description
Desmodium paniculatum is a facultative upland dioecious perennial forb/herb.[1] It uses low amounts of water, inhabits dry clay or loamy soils, and prefers partial shade.[2] In fact, D. paniculatum has shown to contain 24% and 9% more dry weight in 50% and 80% shade, respectively, than in full sun.[4]
Distribution
Desmodium paniculatum can be found from Texas to Nebraska, eastward to Florida, the Carolina's, and Pennsylvania, and northward into Michigan, New York, Maine and parts of eastern Canada.[1] In Alabama, D. paniculatum is the most common species of Desmodium found.[5]
Ecology
Habitat
D. paniculatum is found in pine savannas, flatwoods, bogs, fields, woodland borders, and disturbed areas.[3]
Phenology
D. paniculatum flowers between July and November, peaking in September[3][6] with conspicuous purple colored flowers.[2] Flowering can be delayed and seed production reduced when grown in high densities where competition is prevalent.[7] Seed weights vary by a factor of about 4 due to difference in several interacting variables including nutrient intake, water availability, photoperiod, temperature, and grazing impact.[8]
Seed dispersal
Fruit coats are covered with sticky trichomes that allow the seeds to stick to passing organisms and be carried off until they eventually fall off.[8][9]
Seed bank and germination
Larger seeds of D. paniculatum have a higher rate of germination than smaller seeds.[10] Seeds of D. paniculatum germinate above the ground (Epigeal germination).[11]
Fire ecology
Desmodium paniculatum has less nitrogen concentrations in its tissues 1 year after burning than 3 years after.[12]
Use by animals
D. paniculatum produces seeds which attract birds and small rodents, including upland game birds such as bobwhite quail and wild turkey and rodents such as the white-footed mouse and deer mouse. It also serves as a source of food for cottontail rabbits, livestock, and other hoofed mammalian herbivores including white tailed deer.[13]
