Aristolochia macrophylla Lam.
Pipevine, Dutchman's pipe
Aristolochiaceae (Birthwort Family)
Synonym(s): Aristolochia durior, Isotrema macrophyllum
USDA Symbol: ARMA7
Pipevine or Dutchman’s pipe is a picturesque, deciduous vine, climbing 20-35 ft. by means of twining stems. Fast-growing, green stems bear large (12 in.), heart-shaped leaves, dark-green above and pale-gray beneath. Flower occur singly or 2-3 per cluster and are pipe-shaped, mottled green and burgundy, with yellow tubes. Cylindrical, cucumber-like capsules, 3-4 in. long, stay green most of the summer eventually ripening to gray or black.
A characteristic plant of the southern Appalachian hardwood forests, Dutchmans Pipe is often cultivated outside its native range. Flowers of this genus were once used as an aid in childbirth, since they were thought to resemble a human fetus. The similar Woolly Dutchmans-Pipe (A. tomentosa) has a bractless flower stalk, a yellowish calyx that is purple around the opening, and downy and whitish leaf undersurfaces.
