When to Plant Echinacea in Seminole County, FL

Echinacea (purple coneflower) is a native prairie perennial valued for its immune-supporting properties and beautiful daisy-like flowers that attract pollinators.

Seminole County, Florida is in USDA Zone 9b. The average last spring frost is February 3 and the first fall frost is December 21, giving you a growing season of approximately 321 days.

At an elevation of 260 feet, Seminole County receives approximately 53.9 inches of rainfall annually with predominantly sand soil. Summer highs average 95Β°F, so Echinacea may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring β€” great for early planting β€” but Echinacea will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Echinacea root diseases.
