Rose of Venezuela, Scarlet Flame Bean - small compact tree with spectacular red flowers. This tropical American native occurs in Colombia and Venezuela, though it is widely grown in other tropical regions worldwide. A true tropical, it requires a frost-free environment with high air humidity. Assuming you can provide the tropical conditions, the species grows into a nice medium size tree 20-25 ft (smaller in containers), with dense umbrella-like canopy, spreading 15-20 ft wide.
