Japanese Holly

Japanese holly is the broadleaf evergreen that looks like boxwood but is not, small, glossy, dark green leaves on a dense, compact shrub that shears into formal shapes, fills foundation plantings, and serves as low hedging where a refined, controlled appearance is the goal. The resemblance to boxwood is close enough that Japanese holly is often used as a substitute in regions where boxwood blight has become a problem. It grows three to ten feet depending on the cultivar, with a naturally dense, rounded form. Native to Japan and Korea.

In Western Washington, Japanese holly performs well in sun to part shade with moist, well-drained, slightly acidic soil. 'Convexa' is the classic landscape selection, a mounding, three-to-four-foot form with convex leaves. 'Sky Pencil' is a narrow columnar form useful for tight vertical spaces. 'Helleri' stays under three feet and works as a low hedge or border edging. No significant disease or pest concerns are tracked in this region. The primary cultural caution is drainage: Japanese holly does not tolerate waterlogged soil, particularly in winter. If you want the boxwood look without the boxwood disease baggage, Japanese holly is the practical substitute, especially in the acidic soils that characterize most Puget Sound lowland properties.
