A prairie classic! Purple Coneflower has a fibrous root system with short woody rhizomes. It is a drought-tolerant perennial that is also deer resistant.
The flowers are a golden red to purple and release a slight fragrance in strong sunlight. Blooms appear June–September and some Purple Coneflowers may re-bloom in the fall, especially if dead-headed early on.
Direct sow seeds into prepared soil in late fall once soil temps are below 50°F (usually mid to late November). Can also be planted in winter during natural freeze/thaw cycles and early spring. Plant shallow, no deeper than one-eighth to one quarter inch, and lightly rake to work seed in. Plant in full sun to partial shade. Usually reaches maturity two to three growing seasons after planted, but can sometimes bloom the first growing season.
Wait for flowers to dry completely on the plant, then snip off dried flower heads and place into a paper bag. Once you have brought them inside, you need to remove the seeds from the seed head. This is done by hand. You will have to remove any chaff from seeds, as this may cause the seeds to go moldy when they are stored.
Allow the seeds to fully dry for two to three weeks, then store in a cool, dry place for up to seven years.
