White Supreme Fiberglass Window Boxes

Our Supreme Fiberglass Window Boxes are an owner's dream for a container planting choice. Yes, supreme flowerbox window boxes look fabulous, and that's matched by these fiberglass window boxes' superior performance.

Our supreme fiberglass window boxes move even further toward the idea of long-lasting low-maintenance flower window boxes. A custom drainage mat wicks water to plant roots, but also carries it along the convex bottom to drain holes in the end cap so your plants are never over-watered in a supreme fiberglass window box planter. The drain mat also encourages roots, circulates heat to them and replaces the need for pebbles in the bottom of this window box planter.

Feature-rich, supreme flowerbox window boxes offer four lovely choices of decorative mounting brackets in wrought iron and four hardware options for special situations: mounting in brick, or to a deck, fence or railing. All are exclusive to our fiberglass window boxes. Nothing says peace of mind like custom hardware for your window boxes.

Constructed of three-ply fiberglass, the flowerbox window box is lightweight for easy hanging yet exceptionally strong, and won't split, stain, or discolor in the elements.

Lovely clean lines define the supreme flowerbox window box design, with generously sized molding at the top and bottom of this window box planter. Choose a supreme flowerbox in fiberglass in white, slate grey, satin black or hunter green. Need a different color? These container planters may be painted, too.
