If the shade is due to structures, proper plant selection is important. Here are a few suggested plants for shade areas. For very heavy shade select impatiens, begonia, coleus, browallia, fuchsia and torenia. For light shade, lobelia, nicotiana, red salvia, pansy, alyssum, dusty miller, impatiens, begonia, ageratum, and dianthus are suggested. Hot and dry areas are common along the edges of pavement or in front of light colored, south facing walls.
Intense heat dries the ground quickly and tests the staying power of most annuals.
Protect plants in these locations with a thick mulch and water thoroughly.
