General information/special features: Plant in full sun to partial shade. Bred from Desert Willow (Chilopsis linearis) for desert hardiness and color, and Southern Catalpa (Catalpa bignonioides) for larger blooms. The name is a combination of the two parents' names. The Desert Willow is native to southwestern Utah.
