Description Native perennial woody vine (or less commonly, a shrub). A deciduous vine with purple-striped curving pipe-shaped flowers, whose unpleasant odor is attractive to tiny carrion-feeding insects. After it blooms, the plant sends out new green heart-shaped leaves. Fruits are green winged capsules. The vines grow from rhizomes to a length of over twenty feet and can become quite thick in circumference at maturity.
Habitat moist woods and riparian zones.
Range Northern and central California.
Discussion This plant is the sole food source of the Pipevine swallowtail butterfly (Battus philenor).
