When paired with the right soil and plants, window boxes create effortless curb appeal and decoration. Strategically placing window boxes to complement architectural details gives your home a custom, upscale look without much work. Overflowing with flowers or foliage, window boxes inject year-round vibrancy and natural beauty into your home’s exterior. Whether you prefer classic wrought iron, painted wood, or sleek composites, the right window boxes can completely transform your home’s aesthetic. With a little planning and creativity, lush window box gardens allow you to put your unique stamp on your home’s landscape.
