Vine

Vine maple is the small native maple of Western Washington's woodlands, a tree that shifts form dramatically based on its light exposure. In deep shade, it becomes a sprawling, vine-like scramble of slender stems that weave through the understory, never quite reaching an upright height. In sunlight, it tightens into a multi-stemmed small tree, 15-20 feet tall, with horizontal or even downward-arching branches that create a distinctive spreading crown. The leaves are small (2-3 inches across), nearly circular, and divided into 7-11 lobes; they turn brilliant red and orange in autumn. The delicate flowers appear in spring in clusters of 3-6 with deep red sepals and greenish petals, and by fall the winged seeds (samaras) are distinctive.

In Western Washington, vine maple excels in part shade on acidic, well-drained soils and is invaluable for the transition zone between deep forest and open landscape. It requires consistent moisture during establishment but becomes moderately drought-tolerant once rooted. The tree's unique multi-stemmed character and horizontal branching make it essential for naturalistic design, but this form will disappear if you top it or prune heavily. The bark is smooth and greenish, lending winter interest, especially on branches with southern exposure. It is relatively pest-free and disease-free, though it hosts various scale insects and foliage diseases common to maples. This is a slow to moderate grower that reaches mature size in 15-20 years. The combination of small stature, reliable fall color, and perfect integration into mixed shrub-tree plantings makes vine maple one of the most useful native species for residential landscapes.
