Bignonia capreolata


Crossvine


Bignoniaceae (Trumpet-Creeper Family)



Bignonia capreolata (Crossvine)
Cressler, Alan
A climbing, woody vine reaching 50 ft. long with showy, orange-red, trumpet-shaped flowers 2 inches long and 1 1/2 inches across which hang in clusters of two to five. They are sometimes seen high in a tree, as the vine climbs by means of tendrils. Claws at the end of its tendrils allow crossvine to cling to stone, bricks and fences without support. Leaves are opposite, 46 inches long by 2 inches wide, with a third leaflet modified into a tendril. Persistent, glossy, semi-evergreen leaves change from dark green in summer to reddish-purple in winter.
