Aristolochia macrophylla

Dutchman's Pipe

<< PREV Image 1 of 2 NEXT >>

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.

Native Trivia

During 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.


"We pipevine swallowtails find this plant indispensable. We couldn't live without it!"
