An 11 in deep planting box is unusual on a vertical unit, and it is what lets this 57 in piece grow more than shallow bedding. The box measures 29 by 12 by 11 in and carries 88 lbs, room enough for veggies with real root systems as well as flowers and vines, all on a footprint of 33 by 14.5 in across. Dual lattice trellises rise on either side to support the climbing plants, so vines have two faces to work up rather than one. Crowning it is an arched roof, decorative in itself and shaped so hanging baskets sit naturally beneath the curve, which turns the top of the unit into a third growing level instead of a lid. Water leaves the box through a slatted bottom panel, the gaps between the slats draining effectively where a solid base would hold a puddle under 11 in of soil. The supplied liner sits inside and does the complementary job, preventing soil from leaking out through those same gaps while still letting water pass. Natural pine forms the structure, warp resistant and built to last, finished with a water-based paint and protective oil rather than a heavy varnish. Exquisite craftsmanship leaves the surfaces smooth and splinter-free. It weighs 24.5 lbs and its elegant lines enhance patios, balconies, gardens or indoor spaces.
