Wallflowers are another cool-season annual that can brighten gardens and containers in early spring when we're so eager for color and fragrance. They will bloom alongside pansies, and wallflowers' bright colors often complement pansies nicely.
Wallflowers are short-lived perennials often grown as annuals. The frost-tolerant plants add a bright dose of color to early-spring gardens. Many are delightfully fragrant. They also tolerate poor soil well. They're often used as winter annuals in Southern gardens.
If you can find them in garden centers, plant wallflowers in spring a few weeks to several weeks before your region's last frost date. Otherwise, start from seed, following seed packet directions exactly. Once established, wallflowers tend to reseed freely. They have average water needs; do not overwater.

The delicate, peachy-pink flowers of diascia are something a little different. Found with increasing frequency in garden centers, diascia is a snapdragonlike flower gaining popularity because you can plant it so early in the spring. A perennial in the southernmost regions of the U.S., it's a cool-season annual elsewhere. Plant it a few weeks before your region's last frost for early fall color, especially in containers.In the bed or border, diascia is an airy pick that ties other plants together. It blooms in a wide range of pink shades -- from cool, bubblegum pinks to warmer tones of peach, coral, and salmon. After it blooms in spring, cut it back. It is likely to stop blooming for a while once summer heat hits. When things cool off, it will rebloom. It has average water needs, so don't over- or underwater. Fertilize lightly but regularly.
Few gardens should be without the easy charm of snapdragons. They get their name from the fact that you can gently squeeze the sides of the intricately shaped flower and see the jaws of a dragon head snap closed. The blooms come in gorgeous colors, including some with beautiful color variations on each flower. Plus, snapdragons are an outstanding cut flower. Gather a dozen or more in a small vase and you'll have one of the prettiest bouquets around.Snapdragons are especially useful because they're a cool-season annual, coming into their own in early spring when the warm-season annuals, such as marigolds and impatiens, are just being planted. They're also great for fall color.Plant snapdragon in early spring, a few weeks before your region's last frost date. Deadhead regularly for best bloom and fertilize regularly. Snapdragons often self-seed in the landscape if not deadheaded, so they come back year after year, though the colors from hybrid plants will often will be muddy looking. In mild regions, the entire plant may overwinter if covered with mulch.Shown above: 'Rocket Red' snapdragon
