Chitalpa tashkentensis

About

×Chitalpa is an intergeneric hybrid flowering tree in the family Bignoniaceae. There are two major forms in North America, the 'Morning Cloud' a hybrid of desert willow for desert hardiness and color, and northern catalpa, and the 'Pink Dawn' variety formed as a hybrid of desert willow and either yellow catalpa or northern catalpa. Both forms were originally thought to be hybrids of desert willow and southern catalpa. The name is nothogeneric, or a combination of the two parents' names. Leaves are lanceolate, 10 to 13 cm long and 2.5 cm (1 in) wide, almost always in whorls of three. The trumpet-shaped flowers are 2.5 cm (1 in) long and frilly. The inflorescence is indeterminate, with alternately arranged flowers.
