Silverleaf Sunflower
Majestic, Helianthus argophyllus (Silverleaf sunflower) is a tall, multi-branching annual with a magnificent foliage of silvery felted leaves and a profusion of sunny yellow flowers, up to 4 in. wide (10 cm), each adorned with a chocolate center. One plant can produce up to 1-5 flower heads. Extremely long blooming from mid-summer until the first frost, the blossoms are particularly attractive to goldfinches as they love to eat the seeds directly from the seedheads. Easy to grow, this wild sunflower reseeds freely and grows quickly during warm weather.
