Vernonia lettermanii, commonly called ironweed or Letterman's ironweed, is an upright, clump-forming, herbaceous perennial native to rocky outcrops, floodplains, and river scours in west-central Arkansas and adjacent areas of Oklahoma. Plants can reach around 2' tall with an equal spread. The finely textured leaves are thin and narrow (up to 3" long and around ⅛" wide). Terminal corymbs (branched, flat-topped inflorescences) of bright purple flowers appear in mid to late-summer. Highly attractive to hummingbirds, butterflies, and other pollinators. Synonymous with V. lettermannii.

'Iron Butterfly' is a selection of a wild sport. A bit more compact and floriferous, but with all the terrific attributes of the wild-type.
