Overview

Acer griseum is a stunning small to medium-sized deciduous tree celebrated for its extraordinary exfoliating bark that peels away in thin, papery strips to reveal warm cinnamon-orange undertones beneath. This distinctive feature provides year-round visual interest, making it particularly valuable in winter landscapes. The tree develops an elegant, oval to rounded crown with gracefully ascending branches that create an open, airy canopy. The trifoliate compound leaves consist of three leaflets, with the terminal leaflet being notably larger than the lateral ones. Each leaflet displays serrated margins and a rich green color during the growing season, transforming into brilliant shades of orange, red, and scarlet in autumn. The small, inconspicuous yellowish-green flowers appear in spring before the leaves fully emerge, followed by paired winged seeds (samaras) typical of maples. Acer griseum is prized by gardeners and landscape designers for its multi-seasonal appeal, combining spectacular fall color with the most ornamental bark of any maple species.

Native Range

Acer griseum is native to the mountainous regions of central China, specifically found in the provinces of Gansu, Henan, Hubei, Hunan, Shaanxi, and Sichuan. In its natural habitat, it grows in mixed deciduous forests on mountain slopes at elevations between 1,500 to 2,000 meters, where it experiences cool, moist conditions with well-drained soils.

Suggested Uses

Acer griseum works exceptionally well as a specimen tree in small to medium-sized gardens, where its ornamental bark and fall color can be fully appreciated. It makes an excellent choice for Asian-inspired gardens, woodland settings, and as a focal point near patios or seating areas where the bark texture can be viewed up close. The tree is ideal for providing seasonal interest in mixed borders and works beautifully when planted in groups of three for larger landscapes. Its moderate size makes it suitable for urban gardens and as a street tree in appropriate climates.

How to Identify

Acer griseum is immediately recognizable by its exfoliating cinnamon-colored bark that peels in paper-thin curls. Its compound leaves have three leaflets with the terminal leaflet slightly larger than the two side leaflets.

Care & Maintenance

Care Guide

Acer griseum requires consistent moisture, especially during its establishment period and dry spells, but must have well-draining soil to prevent root rot. Apply a 2-3 inch layer of organic mulch around the base to retain moisture and regulate soil temperature, keeping mulch away from the trunk. Fertilize sparingly with a balanced, slow-release fertilizer in early spring, as over-fertilization can reduce the intensity of fall color. The tree benefits from protection from strong winds and hot afternoon sun in warmer climates. Regular deep watering during drought periods is essential, as Acer griseum does not tolerate prolonged dry conditions well.

Pruning

Prune Acer griseum during late fall to early winter when the tree is fully dormant to minimize sap bleeding. Focus on removing dead, damaged, or crossing branches, and maintain the tree's natural form by making cuts just above outward-facing buds or branch junctions. Avoid heavy pruning, as this species naturally develops an attractive shape with minimal intervention. Remove any suckers that emerge from the base, and thin overcrowded interior branches to improve air circulation. Young trees may benefit from light structural pruning to establish a strong central leader.

⚠️ Toxicity Warning

Acer griseum is generally considered non-toxic to humans and pets. However, as with all plants, ingestion of large quantities of leaves or bark is not recommended and may cause mild digestive upset in sensitive individuals or animals.
