Description

The Devil Maple is native to central and southern Japan and is planted as an ornamental in that region.  In the US, it makes a sturdy tree though not well known, usually 20 to 30 feet tall with a rounded habit. The fruit is its distinguishing feature. The samara is about 1 1/2 inches long with spreading wings and is thick and bristly. Yellow flowers appear on the female tree before the leaves. The male tree has more showy red blooms.  It gets its scientific and common names from the two hornlike appearance of the protruding curly stigmas of its flowers, which are retained on its samara.

The name Devil or Horned Maple comes from the horn-like structures at the inner junction of the fruiting structure.  

Insects, Diseases and Other Plant Problems:  Aphids can be an issue for this tree.  Verticillium Wilt and Fusarium Wilt may be contracted.
