Aristolochia gigantea

Aristolochia gigantea, the Brazilian Dutchman's pipe or giant pelican flower (syn. Aristolochia sylvicola Standl.), is an ornamental plant native to Brazil. Typical of subtropical Bahia and Minas Gerais vegetation, it is a vigorous evergreen climber (vine) with heart-shaped leaves and spectacular fragrant flowers. This plant is cited in Flora Brasiliensis by Carl Friedrich Philipp von Martius. A. gigantea and other tropical Dutchman's pipe varieties pose a threat to the pipevine swallowtail butterfly. The butterfly confuses A. gigantea with its native host plant and will lay eggs on it although pipevine swallowtail caterpillars cannot survive on the foliage.[1]
