Douglas or Rocky Mountain Maple (Acer glabrum v. douglasii)
This shrub or small tree (30-35 feet) has deep red twigs, and fresh spring green leaves that are 3-5 lobed and turn yellow or orange in the fall. It is similar to Vine maple (Acer circinatum), but better adapted to somewhat drier, more open sites. Greenish-yellow flowers bloom in clusters from mid-spring to early summer. This maple likes full sun to part shade, and moist, well-drained soil. An excellent tree for a small yard or large rock garden. More commonly found east of the Cascades, from British Columbia and Alberta south to California and east to Montana and Wyoming, Douglas maple occurs in the San Juan Islands on rocky slopes, forest edges and wooded valleys.
$20 for a bundle of 5 bare-root plants, about 18 to 36 inches tall
