The Story

Plant Bio

Buxus microphylla var. koreana is a slow-growing, dense, multi-branched evergreen shrub known for its small, oval leaves and tolerance for shearing. It is one of the hardiest boxwood species. 'Wilson', commonly sold as Wintergreen, is prized for its excellent cold hardiness and its ability to retain its rich green foliage color throughout winter, unlike many other boxwoods that bronze.

Bloom Period:

EarlyLate

Uses & Benefits:

Its fine texture, dense habit, and evergreen nature make it a superb choice for creating formal garden structure, from low hedges and parterres to elegant topiaries. It provides year-round visual interest and a classic, tidy appearance.

Excellent for defining garden spaces, edging walkways and beds, and creating 'bones' in a landscape design. Its dense structure can act as a low screen or barrier, guiding foot traffic or hiding foundations.

While not a major wildlife plant, its dense branches provide important shelter and cover for small birds and other animals, especially during winter months. The small flowers attract early season pollinators.

Planting

How to Grow

Select a location with at least 4 hours of sun and well-drained soil.
Dig a hole twice as wide and just as deep as the root ball.
Amend heavy clay soil with compost to improve drainage.
Place the plant in the hole, ensuring the root flare is at soil level.
Backfill the hole, gently firming the soil around the roots.
Water thoroughly after planting and apply a 2-inch layer of mulch.

Pro Tip

Ensure excellent drainage and good air circulation to prevent common boxwood blight and root rot issues.
