Cutleaf Coneflower

Rudbeckia laciniata

Also known as: Green-headed Coneflower

Tall yellow coneflower with drooping ray petals and a tall green central cone. Deeply cut leaves. Spreads aggressively in rich moist soils — site where it can colonize freely. Parent of double-flowered heirloom 'Golden Glow'. Young stems have been peeled and cooked like celery as a spring tonic, though the plant is also reputed to poison cattle, sheep and pigs.
