Extremely well kept and healthy Buxus
Box, Common box, Dudeon
Buxus sempervirens (Box). This species is grown for its dark green dense foliage. It is a good species for a formal garden but it is a slow-growing shrub; it can eventually reach a height of 5m.
It will prefer a warm climate though the roots like to be kept cool with a generous mulching. You might need to protect in the winter to keep the leaves from browning due to the cold. Should prune back hard in winter or early spring.
