Aristolochia californica

Aristolochia californica Torr.

California Dutchman's Pipe

Aristolochiaceae (Birthwort Family)

Synonym(s): Isotrema californica

USDA Symbol: arca10

USDA Native Status: L48 (N)

A sprawling deciduous vine with pipe- or S-shaped, purplish-brown flowers on a short stalk. California dutchman’s-pipe is a woody, deciduous, climbing vine reaching 9-15 ft. in length. Unusual purple-striped, pipe-shaped flowers hang from the axils of large, silky leaves.

The unusual flowers of this plant are composed of sepals that continue to grow as they mature; the smaller flowers closely resemble an old-fashioned curved pipe. When fully developed, the flowers emit a foul smell that attracts small flies. These flies enter the flower and cause it to close for a few hours. This traps the insects inside and increases the chance that they will pollinate the flower. The plant is not insectivorous, the flies escape and carry the pollen to adjacent plants.
