Giant Dutchman's Pipe Overview

Aristolochia gigantea is a quick-growing, evergreen vine species from the Aristolochiaceae family. Commonly known by the names Giant Dutchman's Pipe or Brazilian Dutchman's Pipe, after the large size and origin. Aside from its decorative qualities, owing to its large, heart-shaped leaves and dense growth, leaves grow to between 5-10cm in length. The interesting flowers are unpleasantly scented and large, reaching around 30cm. They are coloured deep red-purple, with attractive cream patterning. This plant is easily confused for some of the other species in this genus by the Pipevine Swallowtail Butterfly, Battus philenor. This insect may try to lay its eggs on this plant, thinking it is one of its host plants, however the foliage is toxic to their larvae and they will not survive. This species has earnt a Royal Horticultural Society Award of Garden Merit.
