Buxus sp., or more commonly known as Boxwood, is a plant native to Japan. This shrub was widely used in landscaping, because of its large, evergreen nature and its ability to be easily shaped into hedges. This is a versatile shrub, because it can be used in a variety of spaces both large or small - a 5-10 ft tall shrub, or a small 10-20 ft tree, depending on the situation.

In terms of placement, it does best with either full sun or semi-shade, and for its water needs, it requires regular or moderate amounts depending on the climate. Boxwoods are suitable for growing in USDA Plant Hardiness Zones 5-9.

When growing Boxwood in a pot in cold climates, it is important to make sure to place in the pot in a sheltered, windproof area with plenty of sunlight and to make sure that the pot is not too large (or else it will suffer from root rot). During winter, the pot should preferably be placed in a covered porch or sheltered area to protect from frost in cold, particularly snowy, climates. A light mulch should be added to the pot to help insulate the soil and act as buffer against different temperatures.

For the best chances of survival, a pot of any size should be insulated during the winter to keep the soil temperature above freezing. Regular watering is also highly recommended, even during winter, after the soil surface has dried.
