A favorite in both homes and offices, the peace lily (Spathiphyllum) loves cool, low light areas. It's one of the few houseplants for shade that blooms. The leaves are glossy and dark green. When the plant gets slightly pot bound, or too big for its pot, it sends up flower stalks. Each stalk begins with a light green color, with the tip unfurling into a long-lasting white flower. Spathiphyllums can grow several feet tall and several feet wide, and will live for many years if given the proper conditions. Water when dry and keep the plant in a low light location. They strongly dislike full sun.
