Purple coneflower prefers rich, well-drained soil, but will tolerate low nutrient soils as well. Choose a site with full sun to partial shade.
Seeds need a period of cold, moist conditions for optimal germination. Direct sow outdoors in fall or stratify seed in a refrigerator for 8-12 weeks before sowing. Sow seeds ¼" deep and 4-6" apart. Seeds will sprout in 10-21 days. Thin seedlings so that mature plants are 12" apart.
Keep adequately moist for first year until plants become well established. Somewhat drought tolerant once established.
Delay harvest until second or third year. Harvest roots in spring or fall and above ground parts during the growing season.
Dry and store plants in a cool dark place.
Purple Coneflower is a hardy perennial whose seed matures in late summer/fall. Seed is ready to harvest when dry and brown. Store seeds in a cool, dry place. Seeds are viable for 5-7 years.
