Description
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, T. dichotomum has been found in burned upland pinewoods; longleaf pine forests; annually burned pine savannas; loamy sand of woodlands; loamy sand of open pine-hickory woods; floodplain forests; sandy loam along bluffs; amidst cypress knees on the shores of lakes and ponds; sandy ridges; burned pond pine shrub bog flatwoods; longleaf pine-turkey oak sand ridges; and at the edges of an open limestone glade (FSU Herbarium). It has been recorded in disturbed habitats such as roadsides; deciduous flatwoods clearings; and a mowed meadow. Associated species include Vaccinium stamineum, Trichostema setaceum, Scoparia, Panicum, Andropogon gerardii, Angelica dentata, and Helianthus radula (FSU Herbarium).
Phenology
It has been recorded flowering September and October, and fruiting September through December (FSU Herbarium).
Seed dispersal
Seed bank and germination
High light intensities and large diurnal temperature fluctuations as a result of the tortoise mounds are probably favorable for the establishment of T. dichotomum (Bazzaz 1979 cited by Kaczor and Hartnett 1990).
Fire ecology
Pollination
The following Hymenoptera families and species were observed visiting flowers of Trichostema dichotomum at Archbold Biological Station (Deyrup 2015):
Halictidae: Lasioglossum placidensis
Use by animals
It was found to be one of the most common spring recruits on recently abandoned tortoise mounds (Kaczor and Hartnett 1990).
Bee species, Caupolicana electa and Dialictus placidensis, have been observed on T. dichotomum (Deyrup 2012).
