Buxus x 'Green Mountain'

Green Mountain Boxwood

A tall, upright boxwood valued for its excellent cold hardiness and strong pyramidal form, making it one of the most dependable choices for vertical structure in northern landscapes. Foliage is rich, dark green through the growing season and holds color well in winter with minimal bronzing.

Leaves are medium-sized and densely arranged, creating a formal, architectural appearance. Growth is moderate, allowing it to establish quickly while remaining responsive to shearing and shaping.
