Echinacea (Coneflower) Primadonna White

Echinacea purpurea Primadonna White, commonly known as Coneflower, is a first year flowering perennial garden favorite that produces stately 4" to 5" inch daisy-shaped flowers with nearly horizontal petals and golden-lime raised cone centers on long strong stems, ideal for cutting gardens. Plants grow 30" to 36" inches tall and produce an abundance of blooms per plant making this a delightful addition to garden beds, pathway plantings, containers and landscapes transitioning to native savannas. Winter hardy to zone 3, Primadonna tolerates a variety of climate conditions including humidity, heat, drought and poor soil conditions. Echinacea is a favorite food source for pollinators and the spent bloom cones are an excellent seed source of nutrition for small birds during winter.

Plant Echinacea Seeds: Sow echinacea seed in cell packs or flats, press into soil and cover lightly. Kept at 70°F., germination averages 10-21 days. Can direct sow echinacea seeds into prepared seed beds, ⅛ in. deep in groups of 3-4 seeds, spaced 18-24 in. apart. Thin to the strongest seedling.

Tips for producing beefy echinacea plants under fluorescent lights: To maximize vegetative growth after germination provide 18-24 hours of artificial light per day. Move your echinacea plants outdoors when natural day length has reached 13+ hours (early to mid April). If plants that bloom quickly are your priority, provide 9 hours of light per day for the first two weeks after germination, and then 14 hours per day thereafter.

Grow Echinacea: Full sun. Echinacea will tolerate some drought once established; performance is better with regular water. Purple coneflowers attract bees, butterflies, and beneficial insects. Blooms are long lasting when cut. Plants are deer resistant. Our favorite echinaceas to grow in containers are Cheyenne Spirit, the PowWows—Wild Berry and White, and the Prairie Splendors—Deep Rose, Rose Compact, and White Compact.

However, because successful growth depends on various factors beyond our control—such as planting conditions, weather, and care—we cannot offer refunds for seeds, corms, or bulbs that do not germinate or sprout.

Thank you for your understanding and support. If you have any questions about planting or care, we’re happy to help!
