Selecting Your Window Boxes

The fiberstone and fiberglass window boxes in our collection are incredibly versatile. That means selecting the best fiberglass flower boxes for your space comes down to the space you have and the look you prefer.

Measure your windowsill, then decide if you want your planter to extend past the width of the window or take up a smaller footprint. If your window is large, do you favor one long box or several smaller ones?

Then consider aesthetics. Sleek fiberglass complements many different exteriors, while fiberstone looks particularly sharp with other earthy materials like stucco, stone, wood, or brick.
