A slow-growing broadleaf tree, grows to over 75' tall and 2' in diameter on good sites. Longer lived than alder or cottonwood. Very common in Jackson and Josephine County lowland streamside areas. Ash is tolerant of poorly drained soils and so is found in swamps and wetlands. Good for shade and bank stabilization; an especially good species for swampy, poorly drained sites.
Most often planted as a bare root or container seedling. Compared to some other broadleaf trees in this guide, it does not root well from cutting.
A heavy seeder. Seeds disseminated by wind, germinate best in moist, rich soil in organic matter. Sprouts from the stump after cutting or fire.
