Plants on wheels? The Exaco Calypso Planter with Trellis allows you to move climbing plants from place to place, whether to optimize their sun and rain intake, partition your outdoor space, or create mobile shade for other plants, people, or pets. Locking wheels prevent your plants from cruising without permission. Built in Germany, this planter features a built-in reservoir, double bottom, and water level indicator to simplify maintenance of optimal soil moisture. The built-in reservoir holds 2.5 gallons. This box planter is designed not to leak, so you can also use it indoors with confidence. A durable, 4.5 foot high polyethylene trellis accommodates aggressive climbers. Option to choose from 3 colors: white, green, or grey.
