Japanese Lanceleaf Maple Acer palmatum var. dissectum

The Japanese maple is a short tree in the Sapindaceae (maple) family, native to southeast Korea and central and south Japan, and noted for having many aesthetically pleasing forms. Weeping as well as upright varieties exist, and the species is well noted for its beautiful deep red and orange summer color that deepens into the fall.

Acer is Latin for sharp in and palmatum means shaped like a hand referring to the shape of the leaves. 

Japanese lanceleaf maple is an attractive deciduous shrub or small tree with a low spreading shape and distinctly divided lacey leaves.  The size and leaf colors vary greatly with cultivars.

This tree prefers moist, organically rich, slightly acidic, well-drained soils and grows well in sandy loams. Plant it in full sun to partial shade but where it will get some afternoon shade. Makes a good dappled shade understory plant.  

New foliage may scorch in full sun locations in hot summer areas, particularly if soils are not kept consistently moist. Mulch helps retain soil moisture and keep roots cool. Avoid hot and dry sites and protect from strong winds. Pruning is best kept to a minimum, but if needed should be done in late fall to mid-winter. Spring or summer pruning often results in significant bleeding.  

It works well as a specimen plant near a patio or entryway or planted in groups on the outskirts of a landscape or rock garden.

Insects, Diseases, and Other Plant Problems:  It is subject to no serious insect or disease problems. Young leaves that emerge in early spring can be subject to frost damage. High pH soils cause chlorosis.
