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

Churchill County, Nevada is in USDA Zone 7a. The average last spring frost is May 8 and the first fall frost is October 7, giving you a growing season of approximately 152 days.

At an elevation of 5,306 feet, Churchill County receives approximately 8 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 99°F, so Echinacea may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Echinacea will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Echinacea successfully. Mulch heavily to conserve soil moisture.

Echinacea Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Echinacea needs ~3,638 GDD — county provides 3,686 GDD Good fit
