What is Fumitory?

Fumitory is an annual plant of somewhat variable characteristics, often resembling a bush, but also growing as a low, trailing shrub. It has gray, pointed leaves that, at a distance, give the plant a wispy appearance of smoke (hence the common name). The pink-purple flower blooms in spring. The flowering plant (aerial parts) traditionally has been used in herbal medicine. The climbing fumitory, or Allegheny vine, is a North American plant of another genus (Adlumia). Several genera of the family are native to South Africa.
