Dasistoma is native to the eastern United States, where its range is almost exclusively west of the Appalachian Mountains.[2] Its natural habitat is in dry or dry-mesic woodlands and bluffs, typically on calcareous substrates.[3] It is a moderately conservative species, not being found in highly ecologically disturbed habitats.[4]

Dasistoma is a tall hemiparasitic forb growing to around six feet high. It is short lived, typically an annual or biennial although occasionally perennial. It produces tubular yellow flowers in the summer.[5][4]

  • The genus name Dasistoma derives from Greek for "woolly mouthed", referring to the hairy flower opening[6]
  • Basal leaves in early spring
