The Buxaceae are a small family of flowering plants commonly known as the boxwood family. Members of the family are distributed widely across temperate to tropical regions and together include roughly five genera and about 70 species. They are best known for a few widely cultivated species used in gardens, hedges and as groundcover. For a general overview see Buxaceae family.
Characteristics
Plants in this family show a range of growth forms but share several key traits. Many are herbaceous or low-growing perennials, while others are shrubs or small trees. Most species keep their foliage year-round and are therefore evergreen. Leaves are typically simple, opposite and leathery. Flowers tend to be small and inconspicuous, lacking showy petals, and fruits vary among genera. The combination of dense evergreen foliage and compact growth habit is an identifying feature.
Taxonomy and genera
The family is conventionally treated as containing five genera; many treatments list the familiar genera Buxus, Pachysandra and Sarcococca alongside lesser-known groups. For a concise list of the recognized genera see accepted genera, and for a statement of species diversity consult summaries that note about 70 species. Taxonomic boundaries have shifted with advancing botanical study, but the core concept of the family remains stable.
Uses and importance
Buxaceae species are important in horticulture and traditional crafts. The common boxwood (Buxus spp.) is prized for formal hedging and topiary because of its dense growth and small leaves. Groundcover genera such as Pachysandra are valued for shade gardens and soil retention, while Sarcococca (sweet box) is grown for its fragrant winter flowers. The dense, fine-grained wood of boxwood has long been used for carving, engraving blocks and small turned objects, making it culturally and economically notable. Many species are widely cultivated as ornamental plants.
Ecology, cultivation and issues
Members of the boxwood family occur across a broad range of climates, giving the group a largely cosmopolitan distribution in suitable habitats. They are generally adaptable in cultivation but can be vulnerable to specific pests and diseases; successful use in the landscape depends on matching species to site conditions and appropriate maintenance. Because a few species are heavily collected or have restricted ranges, conservation attention may be required for vulnerable taxa.
Notable distinctions
- Buxaceae are mostly evergreen and often have opposite leaves, distinguishing them from many look‑alike shrubs.
- Flowers are typically small and not produced for show; identification relies on leaves and growth habit.
- Although commonly called "boxwood," the family contains genera used for groundcover and fragrance as well as classic hedging.
