    Would you ever consider placing something as special as a blooming orchid in a window box? Actually, a window box display is an excellent way to highlight several orchids that are in bloom at the same time.

As the season progresses, they will explode up, out, and downward from the container, turning their faces toward the sunshine for two to three months. Memorial Day is the turning point of the spring season in many regions, when tomatoes g...MOREo into the ground and the time comes to pull the pansies that are beginning to get lanky, and replace with warm weather annuals.

A fertilizer containing iron may also be necessary...MORE for hydrangeas growing in window boxes.

    The primrose hasn’t caught on in America as much as in Europe, but these perennial spring flowers can brighten your window box for three to four weeks in early spring. Primroses prefer partial shade, but they can stand full sun in cool summer areas. They are bright enough to stand alone, or you can combine them with other petite spring flowers that won’t overwhelm the primrose’s small stature, like sweet alyssum.
