Aristolochia durior

Common Name: Dutchman's Pipe

A fast-growing vine excellent for screening purposes; it will quickly create a dense screen and shade. The huge 8-10 in. wide, heart-shaped leaves are dark green with a coarse texture. In late spring, pipe-shaped, mahogany and cream flowers are produced but are inconspicuous which is why this vine is mainly grown for its foliage.
