Note: One Japanese Maple can make a landscape…that is if you don’t overcrowd it with other trees and large plants. Therefore, when selecting companions to plant under or around your Japanese Maple, make sure to select low-growing shrubs or groundcover plants that won’t interfere at all with your tree.
