Common box
Buxus sempervirens

Common box grows slowly and densely, with small evergreen leaves that reduce naturally in a pot without needing defoliation, and old specimens develop pale, attractively textured bark. It tolerates deep shade and hard pruning equally well, which is why it has been used for clipped hedging and topiary for centuries before bonsai.
