Buxus sempervirens


Long a tradition in colonial landscapes, Boxwood is a finetextured plant familiar to most gardeners and non-gardeners alike. Eventually reaching 6- to 8-feet-tall (old specimens cab be much taller), Boxwood grows slowly into a billowing mound of soft foliage. Flowers are borne in the leaf axils and are barely noticeable to the eye, but they have a distinctive aroma that irritates some people.

Use and Management

Boxwood makes a beautiful clipped hedge, lending a formal air to any landscape. It looks best when located along a foundation or as a border along a walk or path. Plant it far enough away from the walk unless you plan on regular clipping to keep the walk clear. Locating it several feet away will keep the foliage away from the walk for several years. Its distinctive form and rich, dark color make it less appropriate for mass planting or for specimen planting. It can be clipped into and maintained in virtually any shape. Unpruned plants maintain a more-or-less globe shape.

A partially shaded or sunny spot is best suited for Boxwood. It enjoys a clay or loamy soil with a reasonable amount or organic matter. Sandy soils are usually not suited for Boxwood unless irrigation can be provided, or plants are protected from all-day sun. Soil borne nematodes also enjoy boxwood roots in sandy soils.

Many cultivars exist with various leaf forms and variegation, plant shapes and sizes.

Pests and Diseases

Boxwood leaf miner is the traditional and perennial pest of Boxwood. Infestation rarely kills plants, but foliage can be marred and severely discolored if the infestation is serious. Soil nematodes can be especially troublesome in sandy soils. Roots rot if soil is kept too wet.
