× 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.[2] 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.[3] Cultivars include: 'Pink Dawn' with pink flowers, 'Morning Cloud' with white and pale pink blooms,and a recent addition, "Summer Bells Minsum." It a deciduous tree, branching readily near its base and with ascending branches that form a dense, broad oval crown. It is also highly drought-resistant,a trait inherited from the desert willow.[4]
History
The Chitalpa was created as a hybrid by A. Rusanov of the Botanic Garden of the Uzbek Academy of Sciences in Uzbekistan (then part of the Soviet Union) in 1964.[5] It was introduced in the US by Robert Hebb of the New York Botanic Garden in 1977. Thomas Elias and Walter Wisura from the Rancho Santa Ana Botanic garden gave it the name "Chitalpa" in 1991.[6] The tree is ideally suited to most soils and climates of the southwestern United States.[7]
