For cooler climates, try planting primroses, pansies and violas. Pansies are an especially good choice because they require little maintenance, they thrive in sunlight and shade, and they come in a bounty of colors. Fragrant and vibrant, sweet peas grow best in cool conditions, and bush types are very suitable for window boxes.

For warm climates, you have abundant choices. Petunias, nasturtiums, marigolds and impatiens thrive in window boxes. In hot zones, verbenas bloom in mid-spring, flowering on bushy plants in purple, pink, white and red flowers. Snapdragons are a versatile and colorful plant, but because they vary in height from low-growing dwarf varieties to towering spikes, make sure to check to size of the plants you use.
