Boxwood 'Winter Gem' Characteristics
'Winter Gem' are hardy shrubs that are tolerant to cold, pruning, and many insects. When planted in part shade, a sun-dappled (part shade) option is best.
'Winter Gem' have shallow roots, so avoid adding extra plants at the base as the roots will compete. A thick layer of mulch protects the roots from winter freezing and to help to keep a consistent soil moisture.
While 'Winter Gem' have the best winter hardiness when compared with other Boxwoods, it is still advisable to plant in a location that is protected from strong winter winds. Remove heavy snow accumulations to avoid branch breakage. Remove dead or broken branches to help air circulation and to keep a tidy appearance.
This variety is able to keep its bright-green foliage throughout winter, unlike many other Boxwoods. Root rot is possible in poorly drained soils. Insect visitors are possible but uncommon.
