| Elephantopus elatus|
|Natural range of Elephantopus elatus from USDA NRCS Plants Database.|
Common name: Tall elephantsfoot
A description of Elephantopus elatus is provided in The Flora of North America. It is usually a single plant, up to 1m tall, stems are rigid and brittle, with a pappus (modified calyx), flowers are lavender to white, and achenes are 3.5-4m. 
Distributed from South Carolina, south to Florida and west to Louisiana.
It is found in well drained, open pinelands, longleaf pine-wiregrass sand ridges, slash pine flatwoods, longleaf pine savannas, pine-oak woodlands, pine-palmettos woodlands, oak hammock woodland, edges of river banks, sandhills, and edges of upland mixed forest with exposed limestone. In the dry prairies of South Florida, it is limited to the "Dry Mesic" community type, which is the highest and driest within that landscape, but which occurs on poorly drained to somewhat poorly-drained Spodosols, mostly arenic or aeric haplaquods (Immokalee and Myakka series), with a perched wet-season water table. Is also found in human disturbed areas that have been logged or clear cut (like flatwoods), along the roadsides, and in roadside depressions. Requires high levels of light in open areas. Is associated with loam soil, sandy loam soil, limestone, and clay soil types.  It prefers dry soil to wetter soil. It is found in dry flatwoods and sandhill communities.  The most notable difference in the vigor of the flowering response occurred 1 month after the burns and in the fall flowering censuses. Associated species include Cocculus carolinus. 
It has been observed flowering from July to November. 
This species is thought to be dispersed by wind. 
Seed bank and germination
It was found viable in the seed bank of a pine flatwoods community in Florida in areas fire excluded for up to 29 years.
It responded positively to late winter annual and biennial burns. Is abundant in area where there was a winter burn, observed in annually burned savannas, Longleaf pinelands, and in pine-oak woodlands. 
The following Hymenoptera families and species were observed visiting flowers of Elephantopus elatus at Archbold Biological Station. 
Halictidae: Augochlora pura, Augochlorella aurata, Augochloropsis metallica
Leucospididae: Leucospis slossonae
Megachilidae: Anthidiellum perplexum, Megachile albitarsis, M. brevis pseudobrevis, M. xylocopoides
Sphecidae: Isodontia exornata
Vespidae: Pachodynerus erynnis, Stenodynerus fundatiformis
Use by animals
These bees, Azcgochlora pura, Augochlorella aurata, Azegochloropsis metallica, Anthidiellum perplexurn, Megachile albitarsis, M. brevis pseudobrevis, and M. xylocopoides, were found on E. elatus.
