Effect of gibberellic acid, stratification and salinity on seed germination of Echinacea purpurea cv. Water plants regularly for best results, keeping the leaves as dry as possible. Effect of gibberellic acid, stratification and salinity on seed germination. Moistened vermiculite substituted for PEG solution as a priming medium for purple coneflower seeds since benefits to seed germination or seedling emergence. Space plants at 30-38cm (12-15″) apart in any average, well drained, slightly acidic soil. Once sprouts appear, provide bright light.
