Genus:Buxus

Species:microphylla

Family:Buxaceae

Littleleaf Boxwood is a slow-growing, broadleaf evergreen shrub that adds year-round interest to landscapes. It features the smallest leaves among boxwoods, resulting in a dense foliage that can be easily shaped into medium-sized hedges or trimmed bushes. In spring, it produces small, inconspicuous flowers that emit a pleasant fragrance for a brief period.

Like its relatives, this shrub thrives in moist, cool, well-drained soil and is adaptable to various soil conditions. Due to its shallow root system, it benefits from heavy mulching to retain moisture. Once established, it generally exhibits good drought resistance. It prefers full sun to partial shade but should be sheltered from strong winds and harsh winter conditions, as extreme temperatures can cause some varieties to develop an orangish-brown hue. This plant responds well to pruning, making it suitable for hedges, topiary, or bonsai. To avoid damaging new growth, wait to prune until after the risk of late spring frost has passed. It can be grown in containers, along borders, or as an edging or hedge. Propagation is easily achieved through stem cuttings.

Additionally, Littleleaf Boxwood is resistant to damage from rabbits and deer.

**Insects, Diseases, and Other Plant Issues:**
This plant may be prone to leaf spot and boxwood blight, which can lead to premature leaf drop and dieback. Poor drainage can result in root rot, and it is also vulnerable to boxwood leaf miners and boxwood mites. Foliar damage may occur during severe winter conditions.
