IIndian Bean Tree

The Indian bean tree  is native to southeastern parts of the United States. The 'Indian' part of the name relates to the botanical name given by the European botanist who first recorded it. He named it after the local native American (Red Indian) tribe, Catawba, although he incorrectly wrote 'Catalpa'.

Indian bean tree grows into a large, domed tree growing up to 12m in its native range (typically smaller in Britain). It's grown in UK gardens for its large, heart-shaped leaves, which become smaller as the tree matures. Unusually, the leaves don't appear until late June, and they have extrafloral nectaries on the undersides, which secrete nectar. These are followed by masses of white, horse chestnut-like flowers, with pink and yellow markings. From late summer, long (up to 45cm) runner bean-like pods develop, which burst as they mature, releasing silvery winged seeds.

How to care for Indian bean tree

Mulch annually with well-rotted manure or compost. Protect young plants from frost as young wood can be susceptible to frost damage.

Growing Indian bean tree: problem-solving

Indian bean trees suffer few problems, but may be affected by aphids.  A healthy tree should be able to shrug off attack, while natural predators such as house sparrows will help control them.

Bear in mind that the combination of large leaves, flowers and pods result in a lot of litter around the tree, so you may spend more time than you would expect, clearing beneath it.
