General Description

The robust Korean boxwood is known for its excellent winter hardiness and tolerance to pruning and shearing. It is a dense, rounded broadleaf evergreen shrub native to the mountain forests of the Korean Peninsula and northern China.

Small, oval, deep glossy green foliage covers this shrub all season but may turn yellow or bronzy brown in winter. In spring it offers tiny, fragrant, green-yellow flowers that are visited by bees. The fruit is inconspicuous.

Resilient to a wide range of soils (acid to slightly alkaline), Korean boxwood is also quite tolerant of summer heat and humidity as well as winter cold. It grows best in partial sun and well-drained soils. Full sun exposures are only tolerated where seasons are mild. It benefits from mulching to keep its roots cool and moist. Its primary weakness is a susceptibility to leaf dessication and scald caused by drying winter winds and sun. It may also suffer from fungal blight and leaf spots as well as the three problematic insect pests, boxwood leaf miner, boxwood mite and psyllids. Major pruning is best done early in the season.

Boxwoods have lots of utility in the garden. They are ideal for formal hedges and foundation plantings. They are also excellent plants for bonsai and topiary. Desirable cultivars include the robust 'Winter Beauty' and 'Wintergreen.' Both retain their deep green foliage colors better in the depths of winter.
