Sunflower- Mammoth Grey Stripe

Helianthus annuus

The flowering plant Helianthus annuus is native to the Mediterranean region. The 'Mammoth Grey Stripe' (Common Sunflower) is a tall annual with large flowers that can measure up to 8-12 inches (20-30 cm) in diameter and light golden-yellow petals that cover a dark chocolate central disk. Bees, butterflies, and birds are attracted to the beautiful flower heads that are born atop robust stalks, and they make a real statement in the landscape. It's simple to plant. Large seeds with a decent oil content, Grey Stripe are a perfect sunflower for seed harvest.
