Coneflowers or echinacea flowers are purple in color and resemble black-eyed Susans with their brown centers. Though they are classified as wildflowers, coneflowers are members of the aster family. When planted in full sunlight, they blossom well in almost any type of soil. It is easy to collect the seeds from these flowers to save and plant the following year.
Collecting the Seeds
The best time to collect the seeds from a coneflower is right before the end of its growing season. The petals start to fade, but the center of the flower is where the seeds are formed. Remove the petals from the coneflower. Remove the center, or capitulum of the flower and cut it open lengthwise. The disc florets are pollinated blooms in this part of the plant. Gently rub them so they separate. These will be green in color, located on top of the seeds.
Once separated, the seeds can be dried by spreading them out on a paper towel. Repeat the process with several coneflowers that are near the end of their lifespan. After the seeds are dry, place them in a small envelope and label them for the next planting season.
