Elephantopus carolinianus


Elephant's foot (Elephantopus carolinianus) is a perennial herb with a variably hairy stem that may grow to 1m tall. The leaves are arranged alternately, broadly elliptic in shape, shallowly toothed on the margin, hairy below, and up to 25cm long. The small, whitish or purplish individual flowers are grouped in flower heads, each of which is subtended by several leaflike bracts that give the plant one of its distinctive features.

Rank Justification

Uncommon but not rare; some cause for long-term concern due to declines or other factors.


It grows in open woodlands, woodland borders, and serpentine barrens, often in somewhat disturbed conditions.

Survey Dates

Flowers August - October


In Pennsylvania, it represents a southerly species and occurs at a northern border of its range, and has been found in a few southern, particularly southeastern, counties.



Populations of elephant's-foot are threatened by human-related habitat loss, natural succession, and invasive species. Deer browsing may be a problem in some locations.


Since the species may occupy disturbed habitats, active management may be required to create the proper successional stage and ecological conditions for the species to thrive.
