Helianthus annuus
Common Sunflower has large flower heads with dark centers and bright yellow rays. The flower heads, which turn to face the sun, bloom on tall, hairy stems July-August. Birds love to feast on the seeds, and the nectar is a valuable food source for native bees. Use the taller varieties, which may need staking, in the back of borders, and dwarf varieties in beds or the front of borders.
