This deciduous woody vine is an old-fashioned favorite grown for its large, heart-shaped, glossy green leaves (6-12" long) which can quickly cover sun porches, verandas, pillars, posts, trellises, arbors, fences or walls. It is commonly called Dutchman's pipe because the unusual, 2" long flowers look something like Dutch smoking pipes. They are quite interesting so be sure to look behind the dense foliage, which usually hides them. This is the larval host plant for the blue and black pipevine swallowtail butterfly.

Host plant for pipevine swallowtail butterfly
Wooded slopes, ravines and gaps; mostly confined to the Cumberland and Blue Ridge mountains from West Virginia to Kentucky, Tennessee, and northern Georgia (has naturalized elsewhere in the East).
During the breeding season, male pipevine swallowtails patrol their territory, waiting for females to arrive. After mating, a female lays several rust-colored eggs on the underside of a leaf. They will only lay eggs on plants in the pipevine family because these are the only plants the caterpillars are able to eat.
Easy to grow in full sun or part shade Plant in medium wet, well-drained soil. Prefers rich, moist soil; will not tolerate dry soils. Needs a stout support to climb on. Cut back in late winter to control growth.
