- Broadleaf deciduous tree, 30-50 ft (9-15 m), upright, slightly spreading, variable. Leaves opposite, simple, 7.5-18 cm long, 4-10 cm wide, unlobed on mature trees (almost all 3-lobed on young trees), slightly heart-shaped at base, unevenly toothed, glossy green; in the fall, golden with some red-orange. Flowers small, yellowish, in slender, pendulous, 5-7.5 cm long, clusters (racemes); female clusters longer than male. Fruits, glabrous, about 3 cm long, wings horizontally spread.
- Sun or light shade. Grows in clay, loam, or sand in normal pH range. Somewhat tolerant of wind, wet conditions, and drought.
The typical "species" form may not be in cultivation. Several cultivars exist in commerce but often only sold as Acer davidii. Two of the more common cultivars are:
- ‘Ernest Wilson’ - round compact crown, bark conspicuously striped, leaves unlobed, green
- ‘George Forrest’ - pink-red young stems, leaves reddish when unfolding then dark green, described as both unlobed and 3-lobed, triangular shaped. NOTE: Seedlings of both cultivar may be in the nursery trade under the cultivar name, but of course not identical to the cultivar (van Gelderen and van Gelderen, 1999).
- Acer davidii subsp. grosseri (or Acer grosseri) - leaves are gernerally unlobed but sometimes 3- or 5-lobed; 10-15 flowers per cluster.
- Hardy to USDA Zone 5 Native to central China.
- davidii: after the Jesuit priest, Jean Pierre Armand David, who discovered it in China in 1869.
- Acer davidii is one of several Acer species known as a Stripebark or Snakebark Maple. Some of the others include: A. capillipes, A. pensylvanicum, A. rufinerve, and A. tegmentosum.
- Oregon State Univ. campus: south of Adams Hall on 15th St. at A St. (The leaves of this tree are 3-lobed and some 5-lobed.)
