|Greetings: given the relative cost of purchasing plants, is it feasible to save the seed pods from coneflowers and attempt to start seedlings in the spring?Many thanks for your wonderful service. BV|
|Your can propagate your conflower by division or by seed. Division gives you an exact clone of the plant, where seeds give you a random selection of mother nature's work. You never know what you are going to get because most of the seedling don't stay true (show the characteristics of the mother plant). A tried and true, although odd looking, way to collect seed is to allow the flowers to fade, then cover the flower with a piece of panty hose or paper lunch bag. This allows air flow and the seeds to dry, but won't allow the seeds to blow away in case you don't get out there at the right time.
Once you have the seeds, they require 60-90 days of cold stratification. This can be achieved by either sowing the seeds outdoors in the fall, or putting them in a plastic bag or pill container, putting them in the refrigerator and planting them outdoors in the spring. Seeds germinate very quickly, usually within 10 days of sowing.
