Buxus harlandii

Mature Buxus harlandii have some drought tolerance and better pest resistance than most boxwoods, however, has limited cold tolerance.  In northern areas, it should be planted in a location protected from strong winds.  Winter winds can remove moisture from the leaves, resulting in dehydration and bronzing.

Harland Boxwood is tolerant of pruning, however, pruning should be done after the last frost. Pruning will lead to tender new shoots, which can be damaged by a late frost. Its shallow roots should be protected with a layer of mulch. Limit cultivation around these shallow roots, it can damage the plant. Location and maintenance of this plant can have an effect on its health. Protect from winds and full winter sun by placing in a location where these conditions are limited. Winter winds can cause dehydration and bronzing. Remove any accumulated snow to protect the branches. Thinning plants annually will assist with air circulation. 

This variety leafs out early.

In the deep south, this plant is sometimes grown in containers.
