Catalpa bignonioides (Indian bean tree) is native to southeastern parts of the United States – the 'Indian' part of its name relates to the botanical name Catalpa, after the native American tribe, Catawba.

Catalpa bignonioides grows into a large, domed tree up to 12m in height, though it typically reaches 6-8m over 50 years in Britain. Highly ornamental, it's grown in the UK for its large, heart-shaped leaves, masses of white, horse chestnut-like flowers and long (up to 45cm) runner bean-like pods.

Grow Catalpa bignonioides in a sheltered spot in full sun and fertile, well-drained soil. It's perfect for growing as a focal point in a lawn or at the back of a mixed border, and it makes an excellent summer shade tree.
