Acer palmatum 'Osakazuki'

Common Name(s):

Phonetic Spelling
AY-ser pahl-MAY-tum
Description

'Osakazuki' Japanese maple is cultivar in the Sapindaceae (maple) family and has excellent fall color. Japanese maples are native to southeast Korea and central and south Japan. The genus name Acer is Latin for sharp and palmatum means shaped like a hand, referring to the shape of the leaves.

'Osakazuki' has a rounded form and grows 15 to 24 feet tall. It prefers rich, moist, acidic soil, but will adapt to clay and sandy soils. The plant resists leaf scorch in the sun but will showcase the best leaf color if it is planted in partial shade. Keep it watered during dry spells to keep it looking its best. 

Use this small tree as a specimen or in a foundation planting or Asian garden. It does well as an understory tree in the dappled shade of a woodland garden and tolerates being planted with needled evergreens.

Insects, Diseases, and Other Plant Problems:  Aphids and horse chestnut scale are occasional problems. It may be affected by verticillium wilt.
