Torrey Maple Acer glabrum
Other Common Name(s):
- Description
-
A deciduous shrub or small shade tree with smooth bark in the Aceraceae family. Grows well in a woodland garden. Prefers dappled shade, moist soils, and protection from the wind. It is primarily grown for its ornamental red fruit and has interesting red twigs and stand out yellow-to-red fall color. This is a relatively low maintenance tree, and should only be pruned in summer after the leaves have fully developed, as it may 'bleed' sap if pruned in late winter or early spring. Works well for erosion control.
Seasons of Interest:
Foliage: Fall, yellow to red Fruit: Late summer, red samara Twigs: Winter, red
Exposure: Full sun to light shade
Notes: Multi-trunked
Site: Can withstand sandy, loamy, and heavy clay soils, prefers well-drained soil and needs lots of organic matter and a low pH (acid). It performs best in semi-shade (light woodland) to shade. It prefers moist soil. It will benefit from being planted in a location sheltered from strong winds, frost, and afternoon sun.
Insects, Diseases, and Other Plant Problems: No significant insect or disease problems. Can show chlorosis of the leaves (yellowing) in alkaline (basic) soils. Applying a layer of mulch around the root zone in summer and winter to conserve soil moisture and protect the roots in exposed locations or colder microclimates.
