Acer palmatum 'Osakazuki'
- Phonetic Spelling
- AY-ser pahl-MAY-tum
- Description
-
This Japanese Maple has excellent fall color and resists leaf scorch in the sun. The best leaf color is in partial shade. It has a rounded form and grows 15 feet to 24 feet tall.
They prefer rich, moist, acidic soil, but are adaptable to clay and sandy soils. Keep watered during dry spells to keep it looking its best.
Use this small tree as a specimen, foundation planting, or in an Asian garden. It does well as an understory tree in the dappled shade of a woodland garden and tolerates being planted with needled evergreens.
Propagate it by softwood cuttings or grafting.
Insects, Diseases, and Other Plant Problems: Aphids and horse chestnut scale are occasional problems. It may be affected by verticillium wilt.
