Echinacea purpurea

Common Purple Coneflower.

The easiest Echinacea to grow – germinates without stratification. Vigorous plants with large, purple-petal flowers. Fibrous roots are easy to harvest (other species have taproots). Ht. 24-36″. 7-day stratification enhances germination, but is not critical. Nonorganic. Hardiness Zones: 3-10. Sow any of the Echinacea’s 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.

Packet: Avg. 400 mg. App. 100 seeds.  


GERMINATION: 10-15 days at 65-70°F (18-21°C).
CULTURE: Indoors – 8-10 weeks before planting out. Outdoors – In spring when soil is warm; in groups of 3-4 seeds, 1/8″ deep. Thin.
LIGHT/SOIL: Full sun; average, well-drained soil. Tolerates partial shade.
SPACING: 18-24″.
USE: Cut flowers, borders, mass or wildflower plantings, fresh or dried seed heads.
