Beautiful landscapes don't have to be a lot of work. You can enjoy a low-maintenance garden with beautiful blooms and colorful foliage from spring into fall—it's just a matter of picking the right plants. We've pulled together a group of low-maintenance garden plants that are among the easiest to grow in the South. Several of these perennials are longtime favorites—in fact, you may see them thriving in older gardens that have been untended for years.
Blanket Flower
Heat and humidity don't faze blanket flowers (Gaillarida x grandiflora), a tough native perennial that also can tolerate drought well. In early summer, it begins pumping out brightly colored blooms in warm hues such as yellow, orange, and red. It will continue blooming until frost, especially with a little deadheading.
Growing Conditions: Full sun and well-drained soil
Size: 1-2 feet tall and wide
Grow it With: Salvia and anise hyssop both make good companions for blanket flower because their bloom times overlap and their flower shapes make a pretty contrast.
Zones: 3-10

If the South's summer heat causes your garden to fade, add the versatile, low-maintenance black-eyed Susan (Rudbeckia fulgida). Hot temperatures bring out the best in this summer border and container favorite.
Growing Conditions: Full sun and well-drained soil

Cast Iron Plant
Commonly grown as a houseplant in the North, cast iron plant (Aspidistra elatior) is the perfect pick if you're trying to garden in deep shade in the South.
