Oleaceae > Fraxinus latifolia var. ,

Fraxinus latifolia (Oregon ash) is a member of the ash genus Fraxinus, native to western North America on the west side of the Cascade Range from southwestern British Columbia south through western Washington and western Oregon to central California.[1][2][3]

It can grow to 25 meters in height, with a trunk diameter of 30-80cm. The compound leaves are pinnate, 12-33 cm long, with 5-9 leaflets, each leaflet ovate, 6-12 cm long and 3-4 cm broad, and often show signs of disease and brown rot, even on otherwise healthy plants. The fruit is a samara, 3-5 cm long including the wing.[1][2]


The Oregon ash prefers damp, loose soils, and grows from sea level to 900 meters in elevation, up to 1700 m in the south of the range in California. In central southern California, it intergrades with Fraxinus velutina (velvet ash) of southern California east into Arizona.[1][2]
