Juglans major (Arizona Walnut)

Juglans major
Arizona Walnut, Arizona Black Walnut, Nogal Cimarrón

Arizona Walnut is a deciduous tree commonly found in broadleaf riparian ecosystems in west Texas, southern New Mexico, central Arizona and south into Mexico. The canopy gradually forms a wide-spreading, rounded crown. The leaves are pinnately compound, measuring 7 to 14 inches in length. The catkin-like flowers are separately sexed but occur on the same tree each spring. The fruit is 1 to 1 1/2 inches in diameter, with a thick husk containing a single seed. Fruit production is erratic and heavily dependent on rainfall or irrigation, with alternate bearing years common. Fast growing as a seedling, the growth rate tapers off as trees mature. Older specimens may live for several centuries. It is the only nut bearing tree native to desert regions. Hardy to -10° F. USDA Zone 6.
