Buxus Sinica Var Insularis Wintergreen

Wintergreen Korean Boxwood

A vigorous, upright boxwood valued for its excellent cold hardiness, strong vertical form, and dependable performance in northern climates. Foliage is medium to dark green through the growing season and holds color well in winter, with minimal bronzing compared to many traditional boxwoods.

Leaves are slightly larger than those of common boxwood, giving the plant a bold, clean texture. Growth is moderate, allowing it to fill in quickly while still responding well to shearing and shaping.
