- Description
-
Lace-leaf Japanese Maple is the only dissected form of Japanese maple that has an upright habit. It is very ornamental with leaves being red-tipped in spring then gold fall color. It prefers well-drained acidic, humusy soils in full sun to partial shade. In hot summer areas, it will do best with afternoon shade to prevent leaf scorch.
Use in an Asian garden, small spaces or as a specimen.
Problems: Horse chestnut scale, aphids and verticillium wilt.
