Best grown in average, medium moisture, well-drained soil in full sun to part shade. Prefers sun-dappled part shade and moist, sandy loams with a slightly acidic to slightly alkaline pH. Tolerant of pruning and shearing. Avoid cultivating around plants because they have shallow roots. Roots appreciate a good mulch (1-2”). Thin plants and remove dead/damaged branches annually to improve air circulation. In USDA Zones 5 and 6, this boxwood is best sited in a sheltered location which protects it in winter from strong winds and full sun. Carefully remove heavy snow accumulations as quickly as practicable to minimize stem/branch damage.
‘Green Velvet’ is a broad-mounded, compact form (B. sempervirens x B. microphylla var. koreana) of boxwood that will mature to 2-4’ tall and as wide. Opposite, glossy, dark green leaves are evergreen. Pale green flowers are inconspicuous. Sempervirens in Latin means “always green”.
Boxwoods can be somewhat temperamental plants to grow in the St. Louis area where the evergreen foliage tends to bronze (turn unattractive brownish-yellow) in harsh winters, particularly if plants are located in open areas exposed to full sun and winter winds. ‘Green Velvet’ has good resistance to bronzing, No serious insect or disease problems. Some susceptibility to blights and leaf spot. Root rot can also be a problem in poorly drained soils. The three main insect pests of boxwoods are boxwood leaf miner, boxwood mite and psyllids.
