On the Burpee seeds packet it said: Deep red, gold and burgundy shades with brown disks. Attractive single and semi-double flowers reach 8-10" in diameter. Ideal for back borders and cutting. Annual.

From your friends at Botanical Interests: This exotic-looking sunflower has 4"-6" blooms in fiery shades of red, orange, and burgundy with dark centers. Plants reach 6'-8' tall and look like dazzling jewels when the sun shines through the petals. They have a long bloom period, make pretty cut flowers, and birds will enjoy the seeds on plants that are left standing in fall and winter.
