Buxus macrophylla is also called hedgerow, and Holly is also called Ligustrum lucidum. Buxus macrophylla leaves are smaller than those in Hollyleaf, with bright surface and deep blue color. Buxus macrophylla is generally a multi-rod tree with a spherical shape, black stems, holly is generally single-rod, and the bark is gray. So when distinguishing, we must be careful not to confuse these two plants.
