NOTE: there are many hybrids involving this varietal species and the common boxwood such as B 'Green Velvet' and B 'Green Mountain'. Buxus sinica var. insularis, commonly called Korean littleleaf boxwood, is a dense, compact, many-branched, broad, mounded evergreen shrub with a loose and open habit. A slow grower (to 1.5" per year) which is typically grown as a 2-2.5' tall shrub with a larger spread, but which can reach 5' tall after 25 years if not pruned lower. An extremely hardy variety that is a good choice for northern climates. Apetalous, greenish yellow flowers (separate male and female flowers on the same plant) appear in spring. Flowers are sparse and insignificant, but quite fragrant. Small, ovate, light yellowish green to medium green leaves (to 3/4" long). Formerly known as and sometimes still sold as Buxus microphylla var. koreana. Genus name comes from the Latin name for plants in this genus. Specific epithet means Chinese. Common name of boxwood is in reference to the prior use of the wood to make boxes. Another theory on common name is that boxwood describes the quadrangular (square box cross section) stems of young plants. ‘Winter Gem’ is a Korean boxwood that typically matures to 2-3’ tall and as wide. Synonymous with and sometimes sold in commerce as Buxus microphylla var. japonica ‘Winter Gem’ or Buxus microphylla var. koreana ‘Winter Gem.’
