Fast-growing, x Chitalpa tashkentensis (Chitalpa) is a small to medium-sized, deciduous tree adorned with a low, rounded, umbrella or vase shaped canopy of narrow, pointed, medium green leaves, 6 in. long (15 cm). From midsummer until early fall, ravishing conical panicles of 15-40 trumpet-shaped, pink to white flowers, 1 in. across (2.5 cm), bloom dramatically at the branch tips. The pale grayish-white bark is an interesting silhouette in winter with its naked branches. Chitalpa is an intergeneric cross between Catalpa bignonioides and Chilopsis linearis. It is sterile and does not produce messy seed pods. Chitalpa is a lovely choice for a summer flowering tree in a small garden or patio.
