Discover Acer glabrum (Rocky Mountain Maple), a deciduous shrub, or small shade tree, renowned for its decorative appeal and low maintenance needs. Indigenous to the Western regions of North America, it flourishes in well-drained, organically rich soil types, including sandy, loamy, and heavy clay acidic soils. Best suited for semi-shade to shade conditions, this species is found in three varieties specific to different regions.
Glabrum meaning 'without hair', this tree charms with its smooth stems and leaves. It owes its namesake to the prolific Scottish botanist David Douglas, renowned for his discovery of the Douglas Fir alongside this unique maple species.
Acer glabrum grows to a height of 12-30 feet, spreading 10-20 feet wide with a shrub-like growth in the open and a taller, spindly form among closer stands of trees. Its preference lies in sheltered locations, shielded from strong winds, frost, and intense afternoon sun.
Pruning should only take place in the summer, post the full development of leaves—due to the tree's tendency to 'bleed' sap if pruned in late winter or early spring.
Acer glabrum is cherished for its ornamental red fruit that blossoms in late summer and autumn, along with its distinct red twigs, particularly visible in winter. The fall foliage explodes into a riveting palette of yellow-to-red colors.
In its native habitat, this tree serves excellently for erosion control, finding a home in woodland gardens and as an understory tree. However, it might not be suitable for southeastern regions. Experience the charm of the Acer glabrum - Rocky Mountain Maple - today!
