Description: The Indian Bean tree has large, wonderfully bright green, heart-shaped leaves. It produces a blossom of small trumpet shaped flowers that grow in clusters of up to 40 on a protruding stalk known as a panicle. It is its fruit, however, that gives this tree its name. It grows as long bean like pods that often stay on the tree during winter after its leaves have fallen.
Fact: A 2003 study showed that when an Indian Bean Tree was being eaten by a hawkmoth caterpillar, its leaves produced a nectar that attracted ants. These ants then acted as bodyguards for the tree, protecting it against caterpillars. This is a good example of how plants and insects can have a symbiotic relationship.
