× Chitalpa is an intergeneric hybrid flowering tree in the family Bignoniaceae, bred from Desert Willow (Chilopsis linearis) for desert hardiness and color, and Southern Catalpa (Catalpa bignonioides) for larger blooms. The name is nothogeneric, or a combination of the two parents' names. Leaves are lanceolate, 4 to 5 inches long and an inch wide, almost always in whorls of three. The trumpet-shaped flowers are 1" long and frilly. The inflorescence is indeterminate, with alternately arranged flowers.
Cultivation
× Chitalpa is dry-spell tolerant and fast-growing (several feet a year to 20–30 ft.) and blooms between late spring and late fall. There are two cultivars: 'Pink Dawn' with pink flowers, and 'Morning Cloud' with white and pale pink blooms.
