Let’s take a look at the benefits of growing a southern annual flower garden:
Sprout easily from seed
Flowers develop the first season
Add color while waiting for perennials to bloom
Grow edible flowers
Planting Southeastern Annual Flowers
Annual flowers can be planted from seed for a less expensive way to fill your flowerbeds with beauty. Planting seeds allows you to know exactly what’s been used to feed the plants, important info if you’re growing edible flowers or planting an organic bed. Start them indoors a few weeks before the last frost date in your area to get your beds filled at the earliest point. If your area of the South is prone to a late frost, start with planting cold-hardy annuals like:
Dianthus
Pansy
Sweet alyssum
Petunia
These survive that unexpected frost. Seeds of cold-hardy annuals may be sown directly into the prepared bed, as well as starting them inside. When temperatures are still cool, plant out sprouted seedlings of annual phlox, calendula, and cosmos. These like cooler temperatures, but don’t take frost and will fade quickly in the heat, of which southern regions are known for. While both cold-hardy and cool-season annuals decline as summer heat takes over, many will return when temperatures cool off in fall. In the meantime, add in tender annuals for a colorful show in summer. Tender annuals are those that like the heat of summer and are best started in spring. These include vinca, impatiens, marigolds, and zinnias, among many others. You’ll want some flowers with height among those annual plants that clump or grow near the soil surface. Grow taller varieties of ageratum, tassel flower, or spider flower.
