Acer tegmentosum is cold-hardy down to USDA hardiness zone 5a (-29 °C). At maturity (20-plus years) it can reach a height of 10–15 metres (33–49 ft) and a spread of 8 metres (26 ft), with greenish-grey bark with bright white stripes. Leaves are simple, each up to 12 cm across, round in general outline but with 3 shallow lobes (sometimes with two small additional lobes near the base), and doubly toothed edges.[5][6][4][7] The green leaves turn bright yellow before falling in autumn. Pendulous racemes of yellow-green flowers 7-10 cm long give way to samaras that are 1.1-1.3 cm long.[8]

In cultivation in the UK it has gained the Royal Horticultural Society’s Award of Garden Merit.[3] Cultivars include 'Joe Witt', 'Valley Phantom',[8] and 'White Tigress'.[9]

Though generally not considered a concern for conservationists, it was listed as "vulnerable" in the 2004 Chinese Species Red List.[10]
