Description
A description of Eupatorium rotundifolium is provided in The Flora of North America.
Distribution
E. rotundifolium is distributed from Massachusetts, New York, Indiana, and Oklahoma south to southern Florida and Texas.[2]
Ecology
It has well-documented anticancer activities against various human cancer cell lines.[3]
Habitat
E. rotundifolium is generally found in seepage bogs, savannas, and woodlands.[2] It has been observed in 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. 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. [4] 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.[5]
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.[4]
Phenology
E. rotundifolium generally flowers from August until October.[2] It has been observed flowering from May to November with peak inflorescence in July and fruiting from July to November.[4][6]
Seed dispersal
This species is thought to be dispersed by wind. [7]
Seed bank and germination
It was found in the seed bank of a New England coastal plain pond in Massachusetts.[8]
Fire ecology
It is fire-tolerant.[5] A study on fire seasonality found E. rotundifolium to benefit from summer burn regiments rather than winter or spring burn regiments.[9] Another study found this species to increase in abundance 6 months after a fire disturbance, but to decrease in frequency after this point.[10]
Pollination
E. rotundifolium is considered to be of special value to native bees by pollination ecologists since it attracts large numbers of native bees for pollination.[11]
Use by animals
Medicinally, this species has been used in the past to treat intermittent fevers.[12]
Conservation and management
This species is listed as possibly extirpated by the Maine Department of Conservation, Natural Areas Program.[13] It is also critically imperiled in Oklahoma, and vulnerable in Pennsylvania and Indiana.[14]
