Aristolochia durior - Dutchman’s pipe is a vigorous twining vine that serves as a food source for the pipevine swallowtail butterfly and its caterpillars.

A vigorous grower, it can reach heights of up to 20 or 30 feet tall once mature. Pipe vines are best planted in early spring and, while the plants typically bloom in early summer, the foliage of the vine is its best feature.
