One of the hybrids between the Korean Boxwood x the Common Boxwood selected at Sheridan Nursery Company in Oakville, Ontario. This is probably the most commonly planted cultivar of these Sheridan hybrids. It is a wide pyramidal oval form that gets about 5 feet high. It is cold hardy to USDA Zone 5.

Attractive, tight, pyramidal form. A hybrid developed to have the hardiness of microphylla var. koreana with color of sempervirens. Listed on here as hardy to zone 6 but can really withstand considerable cold in zones 4 and 5. Avoid excessive winter wind.
