Aristolochia

vigorous, handsome, large-leaved vine. Well suited for growing on trellises or other structures, especially where a solid visual screen is desired. A tough, adaptable plant, withstanding full sun and partial shade equally well, and thriving in any sort of well-drained soil. The name comes from the unusual, meerschaum pipe-shaped flowers which appear in late spring. The flowers are small and yellow green in color. Dutchman's pipe is a host plant for the pipevine swallowtail. The flowers provide nectar for the adult butterflies, and the leaves feed the caterpillars. A member of the same family as wild ginger, the roots of Dutchman's pipe emit a pleasant, spicy scent when bruised or disturbed.
