In almost any garden there is a need to choose some plants that will grow well in the shade. The intensity of shade varies as well as the plants that can tolerate it. Deep shade exists on the north side of the house or under a dense canopy of trees. Medium shade exists where buildings or trees interrupt sunlight for a part of the day. Light shade occurs where the light is filtered through the leaves of trees.
In shade plantings there is not usually an abundance of strong flower colors. Annuals that grow well in the shade such as impatiens, begonias and coleus add color to an otherwise dull area.
