Buxus microphylla 'File Leaf'

Korean Boxwood

Plant Type:

BROADLEAF EVERGREEN SHRUBS

Buxus microphylla ‘File Leaf’ (ex: Jonathan Lehrer) – is a curious, rare and quite blue form of Korean Boxwood according to my good friend, Jonathan Lehrer. Slow growing and densely formed, Jonathan’s original plant after many years is only 2.5’ to 3’ tall. The foliage which is relatively narrow, matte-finished and touched with blue. Its habit, at least in containers, is to eventually send up tall stems and will want to be pruned to keep it more full and bushy. Its very nice without much fuss. This neat boxwood would be well-used in a rock garden, foundation plant or any way your gardening heart may desire. Fertile draining soil on the neutral to acid side of the Ph spectrum in part sun, afternoon shade. Organic mulches are very beneficial. Thirty inches tall by thirty-six inches wide in 10 years. Cutting grown.

Genus Overview: Buxus

The Boxwoods are a very useful group of broadleaf evergreen shrubs having, depending upon ultimate size, many landscape applications. They prefer fertile soils on the acid side of the Ph spectrum. Boxwoods tend to be shallow-rooted and benefit from organic mulches. Most can be grown in full sun conditions but are happier in part shade. The smaller growing Korean Boxwoods, Buxus microphylla, seem to hold their foliage color better in part winter shade. The English Boxwoods, B. sempervirens, are the larger growing members of the clan and benefit from wind protection especially in winter. All of the following offerings are cutting grown. (Spring Only)
