The Cambridge Collection offers classic details, a tapered finish, and is an overall versatile planter. Inspired by European interior design sensibilities, it is the perfect addition to your outdoor or indoor space if you're looking for a traditional planter with a twist. We use 100% high-grade Polyethylene resin in the manufacturing process - making our products durable and lightweight. Double-wall design provides the roots and potting mix with adequate insulation from surrounding weather conditions. These planters have a built-in water reservoir that helps promote plant growth.
