Railing Window Box Idea Number One

For a brilliant burst of color, this window box idea hangs planters from your porch or deck railings. Mixing wispy purple fountain grass, bold croton, and trailing sweet potato vine provides masses of texture. Even though the box is tightly packed, each plant stands out, thanks to the varying shapes, sizes, and colors.

Railing Window Box Idea Number Two

Here's another enchanting window box idea for decorating your deck. Because the pansy is a cool-season plant, you can give your window box a new look as the seasons change. Don't be afraid to replace the pansies with a heat-loving plant, such as blue angelonia, to keep the color show going into summer.

A. Pansy (Viola 'Delta Beaconsfield')—3

B. Nasturtium (Tropaeolum 'Fordhook Favorites')—1

Mix and Match Flowers and Foliage

Playing with different shapes and colors of flowers and foliage adds excitement. Here, grassy-looking flax lily leaves appear to burst out of clouds of starry white zinnia flowers.

Think Outside the (Window) Box

No one's ever said a window box has to be an actual box, nor that it must involve a window. Get creative and express your window box ideas. For example, this rustic window box is comprised of a hen nester and vintage farm containers that are filled with shasta daisies, annual vinca, and dwarf gerbera daisies. Succulents, such as hens-and-chicks, echeveria, and sedum, along with trailing bacopa, round out the look.
