Box or buxus are used in all areas of the garden and landscape. From topiary to hedging. We tend to stick with buxus sempervirens for hedging plants. There are slower growing forms but with all box being slow or slowish sempervirens performs best. It has a nice bushy habit and grows quite vigorously to form a shape fairly quickly. They can be clipped any time but most often they get the clip in mid summer after the spring flush.
