Buxus balearica is an evergreen Shrub growing to 3 m (9ft) by 3 m (9ft) at a slow rate.
It is hardy to zone (UK) 8. It is in leaf all year, in flower from April to May. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Bees, flies.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Easily grown in evenly moist, well-drained sandy loams in full sun to part shade. Plants will grow well in a variety of part shade situations, including open sun-dappled conditions or light shade with several hours of morning sun or early afternoon sun. Plants can grow in close to full shade, but typically are less vigorous and more open with decreased foliage density. When grown in full sun, plant foliage is more likely to scorch, bronze in winter or suffer from mite attacks. Plants prefer soils with a pH of slightly acidic to slightly alkaline. Plants are generally tolerant of pruning and shearing. Pruning should never be done prior to the last spring frost date. Pruning too early in spring often promotes tender new growth that may be damaged or killed by a late spring frost. Avoid cultivating around plants because they have shallow roots. Roots appreciate a good organic (e.g., bark or compost) mulch (1-2”). Thin plants and remove dead/damaged branches annually to improve air circulation. Boxwood is best sited in locations sheltered from strong winds, with, if possible, some protection from full winter sun. Foliage may bronze in winter when exposed to half day to full day sun. Winter winds can remove moisture from leaves at a rapid rate, often resulting in dehydration and bronzing. Carefully remove heavy snow accumulations as quickly as practicable to minimize stem/branch damage.
