Buxus sempervirens, the common box, European box, or boxwood, is a species of flowering plant in the genus Buxus, native to Europe, northwest Africa, and southwest Asia. The plants are dense, evergreen shrubs planted in elegant and formal landscapes.
Buxus sempervirens is an evergreen shrub or small tree growing up to 1 to 9 m (3 to 30 ft) tall, with a trunk up to 20 centimetres (8 in) in diameter (exceptionally to 10 m tall and 45 cm diameter). Arranged in opposite pairs along the stems, the leaves are green to yellow-green, oval, 1.5–3 cm long, and 0.5–1.3 cm broad. The hermaphrodite flowers are inconspicuous but highly scented, greenish-yellow, with no petals, and are insect pollinated; the fruit is a three-lobed capsule containing 3-6 seeds.
