California Ash (Fraxinus dipetala) is a species of ash in the Oleaceae (Olive) family native to northwestern Arizona, California, southern Nevada, and Utah, and to northern Baja California. In California, it is found in the Coast Ranges, Sierra foothills, and Peninsular Range at elevations of 300 to 4300 ft.
It is a deciduous shrub or small tree with light to dark green serrated leaves.
Its attractive flowers have two white lobe-shaped petals and are sweetly scented, hanging in fluffy clusters; unlike many Ash species, the California Ash is bisexual, not dioecious. The fruit is a long, flat samara (dry, winged seed), green when immature and hanging in bunches. If pruned up, California Ash makes a lovely flowering, multi-trunked specimen tree.
