The coarse-grained and soft wood is very durable in the ground, and, therefore, much valued for fence-psts and railway ties. Catalpa bignonioides and particularly C. speciosa are sometimes planted as avenue trees. For formal gardens, if low round-headed trees are desired, C. bignonioides var. nana is to be recommended. They grow in almost any somewhat moist soil, and are hardy as far north as New England. Propagated by seeds sown in spring, in the North, best with slight bottom heat, or by cuttings from ripe wood, the varieties often by softwood cuttings in early summer or by grafting on seedlings or on roots under glass in spring; also increased sometimes by layers and root cuttings.
