Buxus sempervirens

Buxus sempervirens, the common box, European box, or boxwood, is a species of flowering plant in the genus Buxus, native to western and southern Europe, northwest Africa, and southwest Asia, from southern England south to northern Morocco, and east through the northern Mediterranean region to Turkey. Buxus colchica of western Caucasus and B. hyrcana of northern Iran and eastern Caucasus are commonly treated as synonyms of B. sempervirens.

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.

The species typically grows on soils derived from chalk, limestone, usually as an understorey in forests of larger trees, most commonly associated with European beech (Fagus sylvatica) forests, but also sometimes in open dry montane scrub, particularly in the Mediterranean region. Box Hill, Surrey is named after its notable box population, which comprises the largest area of native box woodland in England.

In Britain, four Roman burials featured coffins containing sprays of the evergreen box, a practice unattested elsewhere in Europe. Box leaves have also been found from several towns, villas and farmsteads in Roman Britain, indicating ornamental planting.

Box remains a very popular ornamental plant in gardens, being particularly valued for topiary and hedges because of its small leaves, evergreen nature, tolerance of close shearing, and scented foliage.
