Certain ones will tolerate greater amounts of shade.For example, Green Mountain -- a hybrid that grows 3 to 5 feet tall -- can tolerate nearly full shade.

Boxwood can be pruned easily and has the ability to grow from old wood. To maintain trimmed forms and hedges you need to prune them twice a year. The first time should be done around late May or mid-June, after the first growth spurt. You can prune for a second time in September or October so the plants will look tight when winter comes. It is best to do it when the weather is cloudy to reduce the chance of burning the leaves. By cutting them you damage part of the leaves and these will turn brown.
