Hi Natalie! A couple things to keep in mind when trying to get seed from Echinacea plants. Many varieties of echinacea are self-infertile or sterile, meaning that they either can't make viable seeds when pollinated from themselves, or won't make viable seeds at all. This means that you may have more success when the plants are allowed to be cross pollinated. If you did want to try and self-pollinate this plant, you could use an organza mesh bag to protect the flower from bees or other potential pollinators. I know this has been used in daylily hybridizing, but not sure about echinacea. Hopefully this helps! Good luck!
