Plant of this tropical tender perennial vine called Aristolochia Peruviana. This exotic vine in the dutchman’s pipevine family is hardy in zones 9a-10b and blossoms best in light shade and will stay evergreen all year in the above zones. A real attraction on this one is the clusters of bright yellow strange looking blossoms at the bottom of the stem where it comes out of the ground. Mine usually has two flushes of flowers a year.
