- Description
-
Littleleaf Boxwood is a versatile slow-growing broadleaf evergreen shrub that provides landscape interest all four seasons. It has the smallest leaves of all the boxwoods creating a densely packed surface that is easily shaped into a medium-size hedge or trimmed bush. Small non-showy flowers arrive in the spring and provide a nice fragrance for a short time.
Like other boxwoods, it prefers moist, cool, well-drained soil and is adaptable to various soil types. Since the roots are shallow, mulch heavily to help it retain moisture. Once established this plant is typically quite drought tolerant. Plant in full sun to light shade but provide some protection from wind and winter weather as foliage tends to turn an orangish-brown with extremes on some varieties. It prunes exceptionally well shaped into hedges, topiary or bonsai. Do not prune until after the possibility of a late spring frost to prevent damage to new growth. Grow it in a container, along a border, or as an edging or hedge. Propagate by stem cuttings which root easily.
This plant is resistant to damage by rabbits and deer.
Insects, Diseases and Other Plant Problems:
Some susceptibility to leaf spot and to leaf spot and boxwood blight that causes premature defoliation and dieback. Poorly drained soils may cause root rot. Susceptible to boxwood leaf miner and boxwood mites. Foliar injury during harsh winters.
