Context

It is widely planted as an ornamental shade tree, valued for its large, showy white flowers and long, bean-like seed pods. The wood is naturally rot-resistant, making it useful for outdoor applications. Northern catalpa is one of two North American catalpa species, the other being southern catalpa (Catalpa bignonioides), which is very similar in appearance. The tree is hardy in USDA zones 4 through 8. For more on the genus, see catalpa. [2]
