Eleven inches of soil depth sits under a 40 in trellis here, which is a more generous box than most trellis planters carry. The interior runs 21 by 12 by 11 in on a 23 by 14 in footprint, spacious enough to nurture a wide range of plants properly rather than restricting the unit to shallow-rooted bedding. Above it, the lattice is woven into a diamond pattern, and that geometry does two jobs at once. Structurally it gives climbing vines a dense grid of crossing points to grab, closer together than a plain square lattice offers, and it is solid enough that hanging pots can be hooked onto it as well as vines trained through it. Visually the diamonds and the natural pine grain make the piece attractive in its own right, so it earns a place at an entryway rather than being hidden at the back of a bed. Drainage holes in the base remove excess water so plants stay healthier instead of sitting in a saturated box. The wood is strong pine, stable and resistant to warping through wet and dry cycles, and the surface is left bare so it can be customized with colors or designs to match whatever it stands beside. It weighs 13.5 lbs, needs assembly, and suits entryways, patios, balconies and gardens.
