TREES & Plants

Three-flowered maple

The three flowers that give this small ornamental tree its name are inconspicuous, but the shaggy peeling bark and glorious yellow, orange and red fall foliage make up for it. Three-flowered maple tolerates a wide range of soil conditions and is a fine specimen tree for gardens, with a habit that can be upright or spreading.

Verticillium wilt (fungus) is a potential problem for maples.

Disease, pest and problem resistance

This tree is tolerant in a wide range of soils.

Native geographic location and habitat
