Echinacea purpurea - Johnny's Selected Seeds
The easiest Echinacea to grow - germinates without stratification. Vigorous plants with large, purple-petaled flowers. Fibrous roots are easy to harvest (other species have taproots). Also known as purple coneflower and eastern purple coneflower. Ht. 24-36". 7-day stratification enhances germination, but is not critical. Nonorganic. Perennial in zones: 3-10. Sow any of the echinaceas outdoors in the fall to allow the oscillating temperatures and natural rain to stimulate germination. Normally grown for 3-4 years for harvest of sizeable roots. Avg. 7,500 seeds/oz. Packet: 200 seeds.
