Japanese Boxwood Buxus microphylla var. japonica 'Borderline'

Other Common Name(s):

Description

Madonna may loathe hydrangeas, but this plant should push her over the borderline for boxwoods! Found as a branch sport by our friend and noted author of North American Azaleas, Clarence Towe, of Walhalla, SC. ‘Borderline’ has dark green leaves with brilliant yellow/gold margins. No patent or trademark.

The common name of boxwood is in reference to the prior use of the wood to make carved decorative boxes. Another etymology is that boxwood describes the quadrangular (square box cross section) stems of young plants. It works well as a specimen or accent in the landscape and it is also useful in shrub borders or foundation plantings. It is commonly used as edging and in formal hedges.

Foliage of Japanese boxwood will usually remain green in winter if grown in shady areas, but the foliage will usually turn reddish if grown in full sun. Good green color usually returns quickly by mid-spring. Carefully remove heavy snow accumulations from plants as quickly as practicable to minimize stem/branch damage. Plants may aggressively self-seed in optimum growing conditions. Plants are generally tolerant of pruning and shearing as needed. Pruning should never be done prior to the last spring frost date. Pruning too early in spring often promotes tender new growth that may be damaged or killed by a late spring frost. Avoid cultivating around plants because they have shallow roots. Roots appreciate a good organic (e.g., bark or compost) mulch (1-2”). Thin plants and remove dead/damaged branches annually to improve air circulation.
