Seeds from this tropical tender perennial vine called Aristolochia Gigantea Brasiliensis. This exotic vine in the Dutchmans pipe vine family is hardy in zones 8 to 10 and blossoms best in light shade and will stay evergreen all year in the above zones. A real attraction with its huge 12 inch mottled blossoms that seem to suddenly appear overnight. The plants will grown up to 20 feet if let climb on a structure.
