Description Convex-Leaf Japanese Holly is a dense multi-stemmed evergreen shrub with a more or less rounded form. It is noted for having one of the finest textures in the shrub trade.

  Morphology:
Japanese Holly is an evergreen shrub sporting small, curved oval leaves that have a pleasing dark green color. At maturity it will grow to 8’ in both height and width. In general most gardeners plant it in a line and make a formal sheared hedge by pruning it lightly as needed to keep the desired shape. Set new plants 4’ apart.

Japanese Holly differs from boxwood by having leaves which are arranged in an alternative fashion (boxwood’s leaves are opposite).

Female plants will set small black berries (occasionally white or yellow).

  Adaptation:
Convex Leaf Japanese Holly grows well on moist acidic soil. It prefers full sun but can take partial shade. This plant is not considered drought tolerant.

  Pests:
Watch out for spider mites. The best defense is a well watered planting.
