Seeds from this tropical tender perennial vine called Aristolochia cymbifera gonzaga. This exotic vine in the Dutchman's pipe vine family is hardy in zones 8a-10b and blossoms best in part or full sun and will stay evergreen all year in the above zones. A real attraction with its 6 inch contorted blossoms. The very unusual green/gold modeled fragrant blossom is an attention getter and will form along the stem when it reaches about 6 to8 feet. The plants will grown up to 20 feet if let climb on a structure.
