stratify
Sow seeds in trays or directly into the ground in early spring. Expect germination within 2-3 weeks. To improve the germination rate, you may cold condition (stratify) the seeds for two weeks prior to planting. Echinacea will begin flowering in its second year, and will be two or three years old before the roots are ready to harvest. Echinacea seeds are relished by goldfinches and will self-sow if left on the plant over winter.
