Many flowers thrive in full sun. In addition to commonly known flowers, such as roses, marigolds, and other common full sun flowers, a number of taller flowers and flowering bushes also thrive in full sun. By planting these taller flowers and bushes at the back of your gardens and planting more common full sun flowers at the front, you can create a colorful garden that thrives in full sun.
