Noteworthy Characteristics
Buxus microphylla, commonly called littleleaf boxwood, is a slow-growing, densely-branched, broadleaf evergreen shrub. Most cultivars sold in commerce today mature over time to 3-4' tall. Tiny, rounded, leathery, elliptic to obovate, medium green leaves (1/3" to 1" long) with blunt tips are evergreen. Leaves may bronze in winter, but good green color usually returns by mid-spring. Axillary petalless fragrant spring flowers are inconspicuous.
Genus name comes from the Latin name for plants in this genus.
Specific epithet means small-leaved.
Common name of boxwood is in reference to the prior use of the wood to make boxes. Another theory on common name is that boxwood describes the quadrangular (square box cross section) stems of young plants.
'Apple Green' is a dwarf cultivar that typically grows in an open mound to only 8" tall over the first 10 years. Broad-elliptic, dark green leaves grow to 3/8" long. 'Apple Green' was introduced into commerce in the early 1990s.
Problems
Boxwood foliage tends to bronze (turn unattractive brownish-yellow) in harsh winters, particularly if plants are located in open areas exposed to full sun and winter winds. Some susceptibility to blights and leaf spot. Root rot can also be a problem in poorly-drained soils. Plants are susceptible to boxwood leafminer, boxwood mites, and box tree moth, but are usually not affected by boxwood psyllid.
Uses
