Container gardening offers a viable options for those who love to cultivate plants but don't have a lot of space. Containers are functional -- gardeners can move them inside during severe weather, they offer a measure of control over plant size and allow for easy garden redesign. Evergreen shrubs keep their foliage through the winter and offer screening, privacy and year-round texture and colour. When choosing the best shrubs for your outdoor garden, select small, slow-growing species and appropriately sized containers.
