The Hummingbird Vine is a fast growing, high climbing deciduous woody vine that will grow to heights up to 40 ft. The vine's aerial roots that occur along the stems that attach tightly to surfaces. Once the vine climbs to a certain height it grows horizontal branches that reach away from the support in a quest for light and space.
Showy clusters of yellow orange to red trumpet-shaped flowers first appear in summer (earlier in frost-free climates) and are produced continuously until early autumn. The tubular flower buds are 3 - 4 in long and are followed by seed capsule 4-8 in long that often hangs on the vine through the winter.
