Annual. Helianthus annuus. Open Pollinated. Mongolian Giant Sunflower. The plant produces heavy amounts of large 1 ½" long sunflower seeds. The yellow flowers are enormous, grow 18" across, and yield a lot of seeds. When the backs turn yellow, cut the flower, and let it dry upside down. Easy for kids to grow. Great for school projects.
