Stylish square planters add bold color and instant drama to your deck, patio or balcony. Planters have built-in casters, so you can roll them to a sunny spot on the deck, and then out of the way for a party. Self-watering pots minimize maintenance chores and provide plants with the consistent supply of moisture they need to thrive. Made from UV-stabilized polypropylene, they'll hold their bright, high-gloss finish for years.
