Ilex crenata — Japanese holly — is a small-leaved evergreen shrub from eastern Asia that looks far more like boxwood than a traditional spiny holly. Its dense, fine-textured foliage and willingness to be clipped make it a favorite for hedges, edging, foundation plantings, and topiary.

A boxwood look without the spines

Unlike the prickly American and English hollies, Ilex crenata has small, smooth, glossy leaves and a tidy, twiggy habit. Tiny white flowers appear in late spring; on female plants these give way to small, shiny black berries that nestle among the leaves. It is widely planted as a boxwood substitute, particularly where boxwood blight is a concern.

Care tips

Plant it in moist, well-drained, slightly acidic soil and keep it watered while it establishes — it dislikes both drought and waterlogging, and yellows in strongly alkaline ground. It takes full sun to part shade and responds well to shearing, so trim it to shape in early summer after the flowers fade. An occasional feed and a layer of mulch keep it dense and healthy.

Fun Fact

Japanese holly looks so much like Boxwood (Buxus) that it's widely used as a drop-in substitute — especially as Boxwood blight has become a growing concern. An easy way to tell them apart: Japanese Holly produces small, jet-black berries; Boxwood has none.
