Description
A description of Eupatorium rotundifolium is provided in The Flora of North America.
Distribution
Ecology
It has well-documented anticancer activities against various human cancer cell lines.[1]
Habitat
It is found i river bottoms, creek bluffs, slash pine-palmetto flatwoods, near streams, in open-dry habitats, mixed woodlands, savannas, marshy areas, bottomland woodlands, edges of thickets, edges of titi swamps, open boggy areas, Longleaf pine-wiregrass savannas, and well-drained uplands (FSU Herbarium). It is also found in human disturbed areas such as pinelands that have been clear cut and plowed, roadside edges and ditches, in a drainage ditch, in roadside thickets, powerline corridors, in plowed pastures, and in fire breaks bordering pine flatwoods (FSU Herbarium).
It can be found in areas regularly burned every 1 to 2 years in the winter. It can be found in longleaf pine savanna communities.[2]
Associated species include Pinus taeda, P. palutris, P. elliottii, Serenoa repens, Taxodium distichum, Liquidambar styraciflua, Sabatia, Lilium, Eupatorium pilosum, E. semiserratum, E. recurvans, E. leucolepis, E. compositifolium, Ceanothus microphyllus, Ctenium, Rhus, Rubus, Aster spinulosus, Myrica cerifera, Magnolia virginiana, Aristida stricta, Cyrilla racemiflora (FSU Herbarium).
Phenology
It has been observed flowering and fruiting from July to November (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by wind. [3]
Seed bank and germination
Fire ecology
It is fire-tolerant.[2]
