Ring of Fire is a five-inch sunflower having golden petal edges and a ring of red surrounding the chocolate brown center. Decidedly different from other sunflowers, Ring of Fire stands out in a crowd of plain gold or yellow flowers. Later to bloom, Ring of Fire may require 120 days to show bicolor blooms, but this late-season display is often what the garden needs for a fresh new look. Needing a full-sun garden, Ring of Fire plants may reach 4 to 5 feet tall, spreading 2 to 3 feet. The long flower stems are perfect for cut flowers. If not cut, flowers may produce seeds for wildlife, another benefit to growing Ring of Fire.
