Iron Butterfly Vernonia Lettermannii 2 Gal

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. 

'Iron Butterfly' is a vigorous ironweed cultivar selected for its compact, densely mounding habit and showy, long-lasting display of purple blooms.

Easily grown in medium to dry, well-draining soils of average fertility in full sun. Tolerant of various soil conditions, including hot, dry, rocky, and alkaline. Also tolerant of occasional flooding and drought once established. Hardy in Zones 4-9.
