Gardening Ideas 25 Flowers That Thrive In Full Sun By Southern Living Editors Updated on September 15, 2022 Share Tweet Pin Email Trending Videos Photo: VisionsofAmerica / Joe Sohm / Getty Images Sunlight is essential for growing plants, whether outside or indoors because the light is necessary for photosynthesis—the process that converts light, oxygen, and water into energy. Plants cannot grow or bloom without this energy. Therefore, lack of adequate light will result in severely stunted plant growth or even plants dying. On the other hand, there is such a thing as plants getting too much sunlight. Exposure to too much sunlight can scorch, bleach, and damage plants, eventually killing them altogether. However, some plants thrive in full sunlight. The Southern sun is no match for these bright beauties. Southern states are known for intense summer temperatures, and weather forecasts can be challenging for gardeners. When 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 shines. 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 how you plant them, the blooms will be magnificent in the sunshine. 01 of 25 Angelonia Van Chaplin Botanical Name: Angelonia angustifoliaSun Exposure: FullSoil Type: Well-draining, RichSoil pH: Slightly Acidic (5.5-6.2) This beauty is also known as the summer snapdragon.
