Answer: Chitalpa, desert willow and Catalpa are all good choices for shade trees. These produce clusters of white flowers in the spring, followed by yard-long bean pods, but the pods are not fleshy and do not attract birds nor are they messy when they drop. These are magnificent shade trees. You might also consider White oak (Quercus alba). It grows to 80 feet, has good resistance to insect and disease problems, excellent resistance to storm damage, grows on poorly drained soils, in hot, dry areas. A final suggestions is Yellowwood (Cladrastis kentukea) which grows to a height of 40 feet and has excellent insect and disease resistance as well as good resistance to storm damage. The most distinctive feature of the yellowwood is its pendulous clusters of white, fragrant, wisteria-like flowers. The tree may not bloom every year, but the clean foliage and rounded form of this tree would make it worthwhile to plant even if it never bloomed.
