Purple Coneflower Seeds

Cold stratification is the key step for better germination rates for Purple Coneflower seeds. For the spring planting, mix Echinacea Purpurea seeds with fine sand, and store in a plastic bag in the refrigerator for 4-6 weeks before planting. Fall direct sowing skips the stratification process altogether, as seeds get  stratification naturally over the winter. Sow at ¼ inch depth. Echinacea Purple Coneflower seeds germinate in 3-4 weeks once soil has warmed up and moisture is consistent; make sure the soil does not dry out during this time.

Full sun is where these plants shine. They can take partial shade, but don't expect as many blooms or as sturdy stems. Well-draining soil is a must. Echinacea Purpurea seeds can take poor soil, even rocky ground, but wet feet over winter will kill a plant. Water well when they're getting established; after that, Purple Coneflower seeds can take care of itself in dry conditions. Space plants 18-24 inches apart to allow good air circulation.

Deadheading spent blooms will encourage more blooms through late summer. However, some seedheads should remain standing at the end of the season, as they provide food for goldfinches during the fall and add interest in a winter garden. Divide every 3-4 years to maintain plants vigorous, as they spread slowly but steadily. No need to spray, as deer avoid them and serious pests are not a problem. Feed once in early spring with a balanced slow-release fertilizer.
