Catalpa, also spelled Catawba, is native to warm temperate regions of North America, the West Indies, and eastern Asia. They can be recognized by their large heart-shaped to three lobed leaves. The two North American species, Southern Catalpa and Northern Catalpa have been widely planted outside their natural ranges as ornamental trees. The Catalpa tree is found in forests from southern Illinois and Indiana to western Tennessee and Arkansas . First cultivated in 1754, the wood was used for fence posts and railroad ties because of its resistance to rot coupled with the fast growth rate of the tree. Catalpa is also occasionally used as a tonewood in guitars.
In the south, Catalpa trees are traditional sources of fish bait. Catalpa worms, the larvae of Catalpa Sphinx Moths, are eagerly sought in early summer by anglers.
