As the name implies, an intergeneric hybrid of Chilopsis and Catalpa that originated in Tashkent, Uzbekistan.
This is more of an arid-climate plant and requires excellent drainage if attempted in the East; mildew may also be a problem in humid-summer areas. Water and fertilizer speed growth, but do not overwater, to avoid root rot.
Sterile, so won't self-seed or become invasive, but Cal Poly claims it still produces large fruits, which directly contradicts Dirr and UFL who say there are no fruits at all. Long flowering period (due to sterility), plus it's on new growth in the summer. Could this be a substitute for crapemyrtle (Lagerstroemia) in climates where summers aren't too humid?
Borderline hardy in this area (the exact zone cutoff is debated).
