Juglans major, or Black Walnut, is Arizona’s own Black Walnut tree. Similar in habit, shape, and water budget to a pecan tree, this tree provides food for many kinds of wildlife with its small walnuts encased in a fruit that ripens to a gooey, black paste. The flesh and skin of the fruit can be used as ink or for dyeing cloth. Black walnut trees are somewhat common in mid-elevation grassland riparian corridors, mountain canyons, and cienegas in our region from 3500-7000 ft. Look for fruit on the ground in early August.
