20 Flowers That Thrive in Full Sun
Sunlight is extremely important when it comes to growing plants, whether outside or indoors, because light is necessary for photosynthesis—the process by which light, oxygen, and water are converted into energy. Plants cannot grow or bloom without this energy. Therefore, lack of adequate light will result in plant growth being severely stunted, or even result in plants dying. On the other hand, there is such a thing as plants getting too much sunlight. Exposure to too much sunlight can not only result in your plants becoming scorched, bleached, or otherwise damaged, but it can also result in their death. However, there are some plants that thrive in the light.
The Southern sun is no match for these bright beauties. Southern states are known for intense summer temperatures, and that weather forecast can be a challenge for gardeners. When it comes to cultivating flowers, we look for species that can stand up to the often blistering sun of Southern climates. Here, we've rounded up flowers that thrive in full sun. They look good in the summer, spring, or fall, as long as the sun is shining. Plant them as a part of a container, or put them in a beautiful flowerbed to add some color and personality to the garden. No matter which way you work them, the blossoming blooms are sure to be stunners in the sunshine.
