To soften the mass of concrete and stone, try palms, ferns, grasses, or elephant ears in pots. For pops of color, add bright annuals. (This time of year, a lot of youth organizations are selling them—so support them!) The joy of potted plants is you can move them or change them throughout the season to beautify the whole area.
Watch-outs: Remember not to put grass or plants that need fertilizer too close to the pool – fertilizer is an algae invitation! Plus, plants or lawn located too close to the pool make it easier for organic matter like leaves and bugs to wind up in the water.
