- Description
-
Hawthorn maple is a deciduous small tree or large shrub in the Sapindaceae (maple) family native to Japan. With its green to greenish-brown and white striped bark that resembles the skin of a melon, it garners the Japanese name urikaede which means melon. This tree reaches a mature height and width of 15 to 20 feet.
The bark is attractive all year but provides excellent winter interest. Shoots are greenish-red and buds are purple-red. The upright vase shape provides sculptural interest in the landscape and requires very little pruning to keep branches up and out of garden beds.
Provide a location with well-drained soil and occasional watering during summer dry spells. Protect the bark from winter frost and full sun as it is prone to cracking. It is somewhat difficult to propagate and is therefore not very common.
Take advantage of the interesting bark and sculptural branches by using this tree in a winter garden. It is also at home in an Asian themed, pollinator or nighttime garden as it is the larval host plant for moths. The small size makes it ideal for a patio planting.
Insects, Diseases, and Other Plant Problems: No serious problems. See potential insect and disease problem fact sheets to the left.
