Buxus sinica var. insularis 'Tide Hill

Wintergreen Korean Boxwood

A low-growing, spreading boxwood valued for its exceptional cold hardiness and naturally prostrate habit. Foliage is rich green through the growing season and maintains good winter color, making it especially useful where traditional boxwoods struggle with exposure and cold.

Leaves are small and dense, forming a tight, carpet-like texture. Growth is slow to moderate, allowing the plant to maintain its shape with little to no pruning.
