The Buxus includes about 70 species of slow-growing broadleaf evergreens. Most of the garden forms are cultivars or hybrids of two species— B. sempervirens (common box) and B. microphylla (Japanese box). Boxwoods are typically large shrubs or small trees, but most of the varieties used in modern landscaping are dwarf varieties, such as B. sempervirens ‘Suffruticosa’, a popular plant for hedges and topiaries. Another dwarf variety is the Korean (Buxus sinica var. insularis). It reaches a mature height of just two feet tall (with a slightly greater spread). These dwarf boxwood shrubs are prized for their densely packed, light-green leaves and rounded, compact growth habit.
