- Rocky open woods, thickets, stream edges.
- Native to U.S.
- This species can be found throughout much of Missouri but is apparently absent from the west-central and northwest portions of the state. The plant is probably the easiest of the
species to ID in Missouri because of its densely hairy stems and its big flower heads. The plant spreads by stolons and often forms little colonies.
The species epithet - "
" means "pretty."
