‘Winter Gem’ is a Korean boxwood that typically matures to 2-3’ tall and as wide. It is an evergreen shrub that features small, oval-rounded, dark green leaves. Synonymous with and sometimes sold in commerce as Buxus microphylla var. japonica ‘Winter Gem’ or Buxus microphylla var. koreana ‘Winter Gem.’ ‘Winter Gem’ is noted for its ability to retain good green foliage throughout winter, however. If properly sited, plants otherwise require little special care other than annual pruning. No serious insect or disease problems. Some susceptibility to blights and leaf spot. Root rot can also be a problem in poorly-drained soils.
Best grown in average, medium moisture, well-drained soil in morning sun afternoon shade. Prefers moist, sandy loams with a slightly alkaline pH in sun-dappled part shade. Tolerant of pruning and shearing. Avoid cultivating around plants because they have shallow roots. Not tolerant of wet soil.
