The Q&A Archives: Do coneflowers spread by seed?

Question: I have 6 coneflower plants. Will they naturally self seed? or will they need some help? Are Black eyed susans the same?
Thanks, Lisa

Answer: Purple coneflowers (Echinacea purpurea) is perennial; Black Eyed Susan (Rudbeckia) is also perennial so while the tops of the plants will die down this winter, new stems, leaves and flowers will appear next spring. They will also self-sow readily so you won't need to help them along. Enjoy!
