These hardy perennial plants are broadly referred to as Coneflowers. They are highly attractive to pollinators and make excellent cut flowers. They look spectacular in mass plantings.
Sow indoors 8-10 weeks before planting out. If started indoors in late winter, Echinacea may bloom in the first year. It can also be direct sown in early spring or early fall. Germination should occur in 10-21 days.
Sow seeds shallowly at only 3mm (1/8″) deep. If starting indoors, provide total darkness and a soil temperature of 21-25°C (70-75°F). Once sprouts appear, provide bright indirect light ( near the window ). When sprouts are large enough to move outdoors, plant in a sunny location.
Space plants at 30-38cm (12-15″) apart in any average, well drained, slightly acidic soil. Water plants regularly for best results, keeping the leaves as dry as possible. Leave seed heads intact over winter to feed birds and provide shelter for beneficial insects.
