This light, airy, deciduous tree is perfect for locations where you need summer shade but want winter sun, such as on the south side of the house or patio. Graceful, light green leaves provide a splendid backdrop to clusters of large, orchidlike flowers that come in shades of white, pink, red, and purple. Many horticultural varieties of this lovely tree are now available, including some that flower in spring and summer.
Corrective pruning should only be done during the deciduous period from December into February. Prune lightly to control growth, create new flowering wood, and to display the handsome, smooth, gray trunks. It is a native of arroyos in Sonoran and Chihuahuan deserts. The Desert Willow grows to 25-to-30 feet, and the canopy coverage is approximately 314 square feet.
