![]() Please read the germination information as well before ordering. ![]() Original ecotype unknown.Ĭollected in August and September 2022. These seeds are from cultivated plants (several dozen seed-grown clumps growing in my garden), not wild-collected. Native to some of the East Coast states (primarily VA to GA), smooth purple coneflower is federally considered to be a threatened ( no longer endangered, as of August 5, 2022) species. ![]() The basal foliage may die off in fall or remain green through at least part of the winter. The purplish pink petals tend to be slender and drooping but are variable. Smooth purple coneflower produces a clump of basal foliage, then sends up 3- to 4-foot-tall stems topped with large blooms mainly in late spring or early summer to midsummer occasional new flowers may appear later in the growing season. purpurea), but its leaves and stems are distinctly smooth to the touch, unlike the rough leaves and stems of the latter. Smooth purple coneflower ( Echinacea laevigata) is similar to common purple coneflower ( E. Please read the description as well before ordering. Note that this information will not appear on the seed packet you receive. The overall germination percentage may be lower this way, and sprouting may be erratic (happening over a period of weeks to months), but it’s worth considering if you are starting at a non-optimal time (spring or summer). Based on personal experience, I can say that it’s possible for these seeds to germinate without a chilling period. If you sow after early February, consider giving the seeds an artificial chilling period of about 2 months. The flowerhead is about two and a half to four inches wide with a bristly center. The last time I grew this species from seed, I sowed on January 1 using this approach, and seedlings began appearing on April 1. The purple coneflower rays are reddish purple, and droop. The “winter sowing” technique works great with this species. It’s easiest to surface-sow (do not cover) the seeds in a pot in late fall to mid-winter, setting them outdoors in a spot protected from mice so they can get a natural chilling period and then germinate when conditions are right in spring. Germination Information: I recommend these seeds only for gardeners who have experience with seeds that benefit from or require a chilling period.
