Arizona Ash

Arizona Ash Tree

Arizona Ash is a fantastic desert shade tree and has an enjoyable shape and a (relatively) cool shade in summer. However, it grows to become a large tree and if you have an aversion to picking leaves in the fall, it might not be the best tree for you. The male and female flowers are on different trees. The male flowers drop in the spring in large quantities, that can be composted rapidly. The female drops large quantities of one-winged seeds (samara), providing you with a continuous source of seedlings. Scientific name: Fraxinus velutina
Family: Oleaceae, Olive Family

Description: A fast-growing perennial deciduous shade tree native to Arizona & parts of Southwestern New Mexico. The “velvet” is a gray fuzz that covers the young twigs and leaves. Young trees are pyramidal, but the shape becomes more rounded and open as mature height is reached. This is an especially useful shade tree where summers are long, hot, and dry, and where soils are alkaline. It is the species (with its varieties) used most in desert areas, commonly planted as a shade & street tree.
