You may also know echinacea as coneflower. It is a lovely perennial plant with bright flowers in purple, pink, white, and yellow. Echinacea is a hardy wildflower that grows in North America. It is a great addition to any garden. Another good thing about echinacea is that it’s easy for home gardeners to save the seeds. You can save enough seeds to grow coneflowers for years to come if you know how to pick and store them right.
When to Harvest Echinacea Seeds
Timing is the key to successfully saving echinacea seeds. You want to gather the seeds once they are fully mature and dry on the plant. This typically occurs 4-6 weeks after the flowers have finished blooming.
Signs that echinacea seeds are ready for harvesting:
- Flower petals have all dried up and fallen off
- Seed head has turned completely brown and dry
- Seeds feel hard and plump when gently rubbed between fingers
- Seed stalks and stems are dried and stiff
- Seeds come away easily when brushed
Harvest echinacea seeds on a dry sunny day if possible. Damp seeds have a higher chance of molding during storage. Since seeds mature at different rates, check the seed heads every day as they get close to being ready. You may need to collect seeds in multiple stages.
How to Collect Echinacea Seeds
Follow these simple steps for gathering echinacea seeds from seed heads
1. Cut Off Entire Mature Seed Heads
Cut through the stem about 6 inches below the seed head with hand pruners or scissors. Carefully place each seed head into a paper bag or open container while being careful not to pull or twist them.
2. Break Open Seed Heads
Each dried seed head should be rubbed or crushed between your fingers or on a piece of paper one at a time. This loosens the seeds from the chaff and debris. Discard the dry flower parts and keep the seeds.
3. Spread Out Seeds to Dry
Pour seeds in a single layer onto a screen or parchment paper. Allow seeds to dry for 1-2 more weeks in a well-ventilated indoor spot out of direct sunlight. Gently stir or turn them periodically so they dry evenly.
4. Store Echinacea Seeds
Place thoroughly dry seeds in paper envelopes or resealable plastic bags labeled with plant name and harvest date. Put the seed packets in an airtight glass jar or plastic container kept in the refrigerator or freezer. Properly stored, echinacea seeds will remain viable for 2-3 years.
Tips for Strong Echinacea Plants
Follow these tips to help ensure the homegrown echinacea plants from your saved seeds will be healthy and vigorous:
-
Isolate different coneflower varieties by at least 20 feet or cage plants when flowering to prevent cross-pollination.
-
Leave some seed heads untouched in the garden for food sources for birds.
-
Wash hands and sanitize tools between plants to prevent transferring diseases.
-
Store seeds in a cool, dark place with stable temperature and humidity. Avoid temperature fluctuations.
-
Only save seeds from your best, healthiest echinacea specimens. Weak plants yield weak seeds.
How to Grow Echinacea from Seed
Echinacea seeds need light exposure to germinate successfully whether started indoors or direct sown outside.
Indoor seed starting:
-
Sow seeds shallowly in sterile seed starting mix 6-8 weeks before your last expected spring frost. Cover with plastic domes to retain moisture.
-
Place seed trays in a bright, sunny window or under grow lights on a 16 hour on/8 hour off schedule.
-
Transplant hardened off seedlings into garden beds after all danger of frost, when soil is at least 60°F.
Direct sowing outdoors:
-
Prepare seed beds in full sun with loose, weed-free soil enriched with compost.
-
Sow seeds 1⁄4 inch deep in late spring when soil reaches 60°F. Space plants 4-6 inches apart in rows 12-18 inches apart.
-
Gently water seeds. Thin out seedlings for proper spacing.
-
Protect young plants from pests until established.
Common Problems When Saving Echinacea Seeds
Issue: Seeds fail to germinate or have low germination rates
Cause: Harvesting seeds too early before fully mature or inadequate drying
Solution: Allow seeds to fully develop on plants before collecting and dry thoroughly before storage
Issue: Seeds rot or mold during storage
Cause: Storing seeds in cold, damp conditions
Solution: Make sure seeds are very dry then store in an airtight container in a cool, dry location
Issue: Plants grown from saved seeds are weak or spindly
Cause: Seeds collected from weak, diseased plants
Solution: Only save seeds from your healthiest, most robust coneflower specimens
Issue: Saved seeds produce different flower colors or growth habits
Cause: Unintended cross-pollination between different echinacea varieties
Solution: Isolate varieties by at least 20 feet or cage plants to prevent cross-pollination
Final Tips

Why you should save your own Echinacea/Coneflower seeds
Every gardener with a hint of do-it-yourself ethos in them should save seeds from Echinacea (Coneflower) to propagate more plants! One single Echinacea plant can yield 500 or more seeds depending on the available number of blooms in a given year.
Birds, especially gold finches, love to land on the seed heads and pick out the seeds, making you the only one who can stop you. You can then grow as many plants as you want, or your garden can handle for basically no money!.
Coneflowers generally cost $5-$15 in the garden center depending on size. If you are willing to wait until the second year for flowers, then you can have as many plants as you want for very little money if you just grow them from seed!.
I generally grow 10-20 plants per year and it doesn’t cost me anything. I’ve shared them with family and friends, as it is a great way to increase the number of native plants. When people know they can get natives for free from me, they are very open to them

What are the benefits of soaking chia seeds?
Chia seeds are soaked to release nutrients better. The chia seed has a very tough outer shell that is difficult for humans to digest. For this reason, it is key that they soak long enough to release the nutrients inside. It usually takes about 8 hours to soak the chia seeds. During the soaking process, they will expand and release nutrients better. It is also important that you do not let them dry out or have too much water. If you let chia seeds sit for too long, they start to ferment, which can make you sick if you eat too many of them.
