General Description

Korean boxwood is known for excellent winter hardiness and its tolerance to pruning, making it great plant for hedges and topiary. Native to the mountains of the Korean Peninsula and northern and eastern China, this is a dense, rounded broadleaf evergreen shrub to small tree. It has tiny, oval, deep green foliage which turns yellow or brownish (bronze) in winter. The tiny, green-yellow, fragrant flowers are visited by bees in spring.

Resilient to a wide range of soils (acidic to slightly alkaline), summer heat and humidity as well as winter cold, Korean boxwood grows best in partial sun and well-drained soils. Full sun exposures are best only in mildest climates. It benefits from mulching to keep its roots cool and moist. Even though a tough plant, cold drying winter wins along with sun can scald leaves and kill it in colder regions. Use it for a hedge, bonsai or foundation plantings. Variety insularis has become popular in gardens with a number of pleasing cultivars.
