10 Annuals That Thrive in Heat & Humidity (Even in Southern Summers)

Summer in the South is no joke! The temperatures climb, the humidity soars, and many plants begin to struggle. But not these annuals. Today I'm sharing 10 annuals that I personally rely on year after year in my North Carolina Zone 8A gardens because they thrive in heat, humidity, and long growing seasons. These tough, low-maintenance performers provide months of color, attract pollinators, and continue blooming when other plants begin to fade. Whether you're gardening in the Southeast or simply looking for annuals that can handle extreme summer conditions, these proven performers deserve a spot in your garden.
