Comments
A member of the Bignonia family, related to Campsis Radicans: Trumpet Vine, and sometimes mistaken for it. 'Tangerine Beauty' is the most adaptable cultivar and somewhat less invasive. While this plant is usually described as having medium water needs, it will tolerate much less once established.
