Rainy Side Notes
Acer palmatum species are valuable in the landscape as a specimen or accent plant in many garden situations. Regular irrigation is important during our summer drought. A deep soaking is preferable over frequent shallow watering.
Acer is the Latin word for maples, and palmatum means hand-like.
