Native to (or naturalized in) Oregon:
- Broadleaf deciduous tree, 50-60(80) ft [15-18(24) m], vase-shaped, low branched. Bark smooth-gray initially. Leaves simple, alternate, ovate to oblong-ovate, 2.5-5 cm long (on some shoots to 13 cm long), sharply serrate with acuminate teeth, parallel veins, 8-14 vein pairs, dark green and somewhat rough above (similar to a small-leaved elm, and related to Ulmus); fall color is variable and may range from yellow, yellow or orange bronze, orange, red and reddish purple. Flowers are small, green and inconspicuous. Fruit small triangular drupe, about 2mm long, green then brown.
- Sun, prefers moist, deep soil, pH adaptable; once established, wind and drought tolerant. Some considered it a good substitute for American elm, for it is resistant to Dutch-elm disease, but generally it has not gained acceptance as a substitute. Relatively slow growing.
