Phonetic Spelling:AY-ser pahl-MAY-tum

Genus:Acer

Species:palmatum

Family:Sapindaceae

This Japanese Maple showcases stunning autumn hues and is resistant to leaf scorch when exposed to sunlight. For the most vibrant leaf color, it thrives best in partial shade. The tree typically reaches heights between 15 and 24 feet and features a rounded shape.

While it flourishes in rich, moist, and acidic soil, it can also adapt to clay and sandy conditions. To maintain its optimal appearance, ensure it is adequately watered during dry periods.

This small tree is ideal for use as a focal point, in foundation plantings, or within an Asian-themed garden. It also performs well as an understory tree, benefiting from the dappled light of a woodland setting, and can coexist with needle-bearing evergreens.

Propagation can be achieved through softwood cuttings or grafting techniques.

Potential issues include occasional infestations of aphids and horse chestnut scale, as well as susceptibility to verticillium wilt.
