Nineteen inches across the outside and 16 inches at the core, these two balls fill a mid-size urn without the trimming a live boxwood would need every few weeks. Outer leaves run three layers deep, which keeps the surface bushy and the shape round from any angle, and the green tone does not yellow as the seasons change. Durable UV-proof PE handles outdoor placement, and the 6-pound pair lifts easily onto a pillar or a wall bracket. Pots with an 11 to 15 inch opening hold them at the right height. There is no watering, fertilizing, or sunlight to arrange, which makes them practical for a rental balcony or a storefront that nobody tends daily.
