Ilex crenata

Common Name(s):

Description

Japanese Holly is a handsome evergreen shrub in the Aquifoliaceae family. The shrub is dense, rigid, compact, and grows up to 12' tall. You will find this plant often used to make topiaries and its showy red fruits provide much-needed winter interest in the landscape.

Plant in the full sun to partial shade in acidic well-drained soil though it tolerates a wide range of soil types.  The shrub can be severely pruned to manage its size so it works well in small spaces.    It tolerates drought, shade, air pollution, poor soils, and clay soils. It is easily transplantable and has a slow growth rate. There are many cultivars available.

Insects, Diseases and Other Plant Problems:  No serious problems.  Spider mites and nematodes are occasional pests.  Alkaline soils will cause the leaves to yellow.
