From the forests of Central and South America. These fast-growing, vining shrubs have drooping, tubu- lar or trumpet-shaped flowers in clusters of up to 20 near ends of branches. Blooms from early spring through fallor year-round in frost- free areas. Leaves 58 in. long, 13 in. wide. Fruit is pulpy berries.
Lax growth is best staked up, espaliered, or draped over a fence or wall. Prune selectively to maintain size and shapeand to keep the flowers coming. Avoid pruning in late fall or when cold weather approaches. Hard prun- ing delays bloom. Protect from hard frosts. Cucumber beetles love to eat the leaves.
