Aristolochia grandiflora aka Duckflower

Aristolochia grandiflora, also known as the pelican flower or Brazilian Dutchman's pipe, is a fast growing deciduous vine that produces one of the largest flowers in the world. The flower emits an odor that resembles rotting meat, attracting flies. The flower itself is burgundy velvet netted with distinctive ivory white veins, resembling a Dutchman's pipe. This woody evergreen climber is native to humid forested areas from Costa Rica and Panama to Brazil, and typically grows to 15-20' long with light green leaves to 6" long. After blooming in early summer, the flowers are followed by papery capsules containing many seeds. Pelican flower is a rare houseplant that thrives with regular watering, direct light within one foot of a window, and well draining soil supplemented with organic fertilizer during peak growing season.
