91% germination rate tested 2024 DAYS TO GERMINATION: 10-15 days at 65-70°F (18-21°C). SOWING: Transplant (recommended): Sow 8-10 weeks before planting outside. Transplant into cell packs or larger containers after the first true leaves appear, 30-40 days after sowing the seed. Harden off and transplant outside in late spring or early summer. Direct seed: Sow in spring when soil is warm, 65°F (18°C). Sow in groups of 3-4 seeds, 1/8 deep. Thin to one plant. Sow in the fall to allow the oscillating temperatures and natural rain to stimulate germination. LIGHT PREFERENCE: Sun. Will tolerate partial shade. GERMINATION NOTE: Seeds germinate most readily if first stratified (kept moist and refrigerated, or sown in a cold frame in the winter.) See individual species for number of recommended days of stratification. The germination rate for non-stratified seeds can be low and erratic. Sow any of the echinaceas outdoors in the fall to allow the oscillating temperatures and natural rain to stimulate germination. Normally grown for 3-4 years for harvest of sizeable roots. 250 Seeds = 1 gram
