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.
