- Description

Devil Maple is a deciduous tree in the maple family (Sapindaceae) native to central and southern Japan and is planted as an ornamental in that region. In the US, it makes a sturdy landscape tree though not well known. The genus name means maple and the species name means relating to the devil. The common name devil or horned maple comes from the two hornlike appendages of the protruding curly stigmas of its flowers, which are retained on its winged fruit, a samara.
Mature height is 20 to 30 feet with a similar spread and a rounded habit. It prefers full sun to partial shade in moist well-drained soil.
Yellow female flowers that are not particularly showy appear on the female tree before the leaves. The male tree has slightly more showy red blooms. The real distinguishing feature for this tree is the winged samara which is distinctly thick and bristly.
Plant this tree as a specimen in an Asian-themed garden or in a lawn or along a slope. Because it supports moth larvae it would be an excellent addition to a pollinator or nighttime garden.
Insects, Diseases, and Other Plant Problems: Aphids can be an issue for this tree. Verticillium Wilt and Fusarium Wilt may be contracted. See potential insect and disease problem fact sheets to the left.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common maple diseases and insect pests.
