Potted plants such as arborvitae or clumping bamboo can be positioned to create a green screen around a raised deck seating area. Ideally, pots should be raised up on casters or made of lightweight materials so you can easily move them for parties or deck repairs. For a long-lasting container display, combine showy annuals with ornamental grasses, shrubs that change leaf color in the fall, or dwarf evergreens. Go for a mix of colors, textures, and foliage types.
