Boxwood Shrub

Common boxwood (Buxus sempervirens) is a dense, fine-textured evergreen shrub that provides year-round structure. It can grow into a substantial rounded plant or be maintained as a hedge, border, or clipped topiary. ## Form and landscape use The [North Carolina Extension Plant Toolbox](https://plants.ces.ncsu.edu/plants/buxus-sempervirens/) describes the species as broadly rounded and multi-branched, with dark green leaves and a mature height that can reach 15–20 feet when unpruned. The [University of Florida IFAS profile](https://ask.ifas.ufl.edu/publication/FP080) lists common boxwood uses including borders, edging, foundations, and hedges. Cultivars vary widely in eventual size, so choose a named selection when space is limited. ## Growing conditions Provide full sun to partial shade and well-drained soil. Boxwood has shallow roots; a mulch layer helps keep the root zone cool and moist. Avoid planting too deeply and protect evergreen foliage from drying winter winds. The University of Illinois Extension gives a general hardiness range of zones 5–8, while other regional sources note that suitability depends on cultivar and local conditions. ## Seasonal interest The small flowers are not showy; the main contribution is the persistent green foliage and clipped form. ## Maintenance Prune to maintain the desired hedge or topiary outline, and thin dense growth periodically to improve air circulation. Monitor for boxwood blight and common pests such as leafminers, mites, and psyllids.
