Algreen Crete 20" Self-Watering Planter, Round, Black Resin

The Crete Self-Watering Planter combines clean modern form with a hand-finished texture inspired by natural concrete, bringing architectural presence to patios, decks, front entrances, and garden pathways without feeling heavy or industrial. Its gently tapered silhouette creates a strong yet versatile profile suitable for both indoor and outdoor spaces. Available in 16.5", 20.5", and 26.5". A built-in reservoir beneath the soil delivers steady root-level hydration. Water is added through the top fill port and stored below the root zone, where roots naturally draw moisture upward as needed. The insulating double-wall polyethylene construction resists cracking, fading, and chipping while remaining lighter and more manageable than traditional concrete. Designed to function beautifully on its own, or with the option to use harvested rainwater as part of the Rainwatr™ system — helping you put stored rainwater directly to work in your planters. Backed by a 10 year manufacturer’s warranty.
