According to the University of Florida IFAS Gardening Solutions, the gaillardia (Gaillardia spp.) plant family, often known as blanket flowers, is distinguished by the vibrant reds, oranges, and yellows that are present in its blossoms. These drought-resistant flowers are available in both annual and perennial forms, and some of them may survive in the USDA plant hardiness zones ranging from 3 to 11. Gaillardia is a plant that does well in full sun and in a variety of soil conditions. After the bloom has been pollinated, the brown core of the gaillardia will transform into a seed head. When planted and cared for correctly, seeds may easily develop into plants. Planting the seeds of gaillardia should be done six to eight weeks before the date when your region typically experiences its last average frost.
