Our Boxwood Obelisks are constructed with a durable, coated metal frame, which is covered with Enduraleaf boxwood. Enduraleaf Greenery is manufactured to withstand sun and weather for years of outdoor use. Although the frame is heavy duty, the Obelisk is light, and should be staked into the ground or mounted in a planter for stability (as shown). A planter also provides additional height in the landscape. Select the ‘Obelisk w/frame’ option and then choose one of the suggested planters and we will secure the topiary to the container for easy installation in your project.
