This year I want to grow Echinacea "Cherokee Spirit". The colors are very nice, and the plants are more compact and bushy, compared to species Echinacea. They are expensive, so I ordered seeds. Species Echinacea seed requires cold stratification. The seed packet did not mention that, so I'm stratifying half and starting the other half directly. I don't know, but maybe early starts will give first year flowers. With species Echinacea, I don't get flowers until the second year.
I use the same method that usually works for me - place the seeds on a moistened paper towel, place that into a zipper sandwich bag, and place that in the refrigerator for two months.
I'm also starting some Goldenrod. Same method.
