Russian Mammoth Sunflower
Helianthus annuus
These impressive sunflowers can grow up to 12 feet tall. The massive stalks are filled with large heart shaped leaves and produce flower heads up to 14 inches in diameter. Flowers are brilliant clear yellow and produce white and grey striped seed. Easy to direct sow and the large blooms are attractive to birds and bees. Seeds can be picked and roasted. Just get them before the Blue Jays do!
