Cutleaf coneflower (Rudbeckia laciniata), also called green-headed coneflower or tall coneflower, is a hardy native perennial that grows beautifully in Tennessee. It’s especially great for pollinators and naturalized garden areas.
Here’s a practical, Tennessee-friendly growing guide:

Maintenance Tips
