Although the first step might seem straightforward, it is significantly more crucial than you might realize. Once you have recognized certain plants, you can determine whether they are actual native species or cultivars if they are found in the wild.
However, you should be mindful that the plant might be a hybrid if you plan to save seeds from a neighbor’s strangely colored (orange, white, or red) coneflower. The seeds will produce a different flower if it is a hybrid. (More information is provided at the article’s end.)
Collect seed heads
The seeds will begin to form a few weeks after the flowers have finished blooming. There are really two locations on the seed head of echinacea where seeds can be gathered. both inside the actual “cone” of the cone flower as well as at the base of each petal.
Echinacea seed heads can be harvested whenever they begin to turn brown or dry out. Either 5 or 6 below the seed head is where you should make the cut. Alternately, hold the seed head gently and make an incision immediately below it. These should go in a paper bag.
Before harvesting, you should allow the seed heads to completely dry out. Alternatively, you could give the seeds themselves a week to completely dry out.
Remove seed from the seed head
Here’s where my method for preserving echinacea seeds shines the brightest! The “cone” or seed head is highly thorny and unpleasant to handle, as you are already aware. Therefore, we will do something far better than using clippers to cut the seed head open and release the seeds.
Obtain a container with a minimum 6 diameter and 6 height, such as a used coffee can made of plastic. Place a few seed heads into the coffee can, shut the lid, and give it a good shake! The seed will come free from the cones after shaking for roughly 10 to 20 seconds.
Simply lift the top and take out the (now-empty) coneflower seed heads at that point. The majority of the good, live Echinacea seed will be what is left in the can (and a small amount of chaff). The seed can now be allowed to dry for another week or two on a plate or in a cool, dry area (and not in direct sunlight).
Sift the seed to remove chaff (Optional)
I also have another suggestion if you don’t want some chaff mixed in with your seed. A standard kitchen strainer can be used to get rid of the chaff. Simply pour the seed/chaff mixture into a strainer and twirl it around lightly.
Most of the chaff will either fall or blow away if you do this outside. Much of it will fall through the strainer if it is inside. Everything depends on you. Hey, to each their own, but I don’t mind the chaff.
Store the seed
I keep my echinacea seeds in a variety of plastic jars or containers. Zip-lock bags or plastic baggies also work well. I’ve found that the seed will remain healthy for a number of years following harvest. However, the proportion of seeds that will sprout gradually declines with time.
Additionally, I have uploaded a video to YouTube that details the procedure. In order for you to witness the entire procedure from beginning to end in action, I’ve provided a link to the video below.
Want to know the best techniques for germination of echinacea? Below is a thorough description of how to cultivate coneflower from seed that addresses any and all queries (stratification, planting depths, etc).
How are purple coneflowers grown from seeds?
One of the simplest perennials to raise from seed is echinacea. It is a perennial herbaceous flower that is popular for flower beds and is indigenous to North America. Over the years, I’ve successfully sown hundreds of coneflower seeds, and I’ll offer my step-by-step instructions below!
Direct sowing or planting seeds in seed starting pots at a depth of 3-6 mm is required for echinacea or coneflower. Leave them in a spot that receives morning sun and afternoon shade, and keep the soil moist (not wet). Normally, seeds germination takes two to three weeks.
As the most popular variety of Coneflower and one that does not require any cold, moist stratification to attain a high germination rate, Echinacea Purpurea will be the focus of this essay. Other Echinacea species will need to be stratified in the cold or sown in the winter.
Materials Required
- Pots this can be a straightforward six-pack for starting seeds or even just an old plastic container with drainage holes punched into the bottom.
- Seed starting mix or potting soil
- small trowel or shovel for the garden
- watering bottle with sprayer
- Seeds
- Note
- You can read our article here to find out how simple it is to save your own Echinacea purpurea seeds.
How to plant Echinacea or Coneflower Seeds in Pots or in the ground
- To about 1/2 (12 mm) below the top of the pot, add moist potting soil. It is easiest to hydrate your soil in a bucket before adding it to the pot, even though it should be damp. Spraying water into the container as you add soil, though, will make it simple for you to do. You want the soil to be damp, not drenched.
- Put three to five seeds in each cell or container. In the dirt, firmly press them.
- Water after applying 1/8 to 1/4 of the soil (3-6 mm) over the seeds.
- Place the seeds in a wet spot that will receive morning sun.
- Within two to four weeks, germination ought to take place.
- The seedlings must then be taken care of until they are several inches tall. placing them in their ultimate location at last.
- Be aware that rabbits enjoy eating immature echinacea plants. The first year, you might want to protect them with chicken wire or liquid fence (at least).

Some notes about watering, and how moist should ‘moist soil’ be
I usually water any seeds I’m germination in the mornings before I leave for work. I water them till the soil is black and moist and the pot feels heavy when the weather forecast calls for sunny days or warm temperatures. In this manner, I am able to ensure that the dirt in the pot is moist to the top.
I’ll check to see whether they need to be watered once more when I get back in the afternoon. I will use a pump sprayer to add more water if the pot seems light in weight or the top of the soil is really dry. I’ll keep doing these two things up until germination.
I won’t water in the afternoon and seldom ever at night once the seeds have sprouted and I have seedlings. I stay away from this because of a condition called damp-off disease. A fungus called damp-off disease has the power to weaken stems and kill young seedlings. Therefore, it is better to avoid letting the seedling sit in totally saturated soil for an extended period of time.
How and When to Transplant Echinacea
Your seedlings are more than ready to be planted in their permanent position once they reach a height of 3 to 4 inches.
- Create a hole that is twice as broad and slightly deeper than the pot.
- At the bottom of the hole, place a handful of compost and gently stir it in.
- Wait for the water to drain after watering the hole.
- Put down your Echinace and cover the pot with soil. Consolidate the soil.
- Keep your seedling safe. Apply liquid fence; it truly works; alternatively enclose the plant with chicken wire and stake it.
Your seedlings can be transplanted in the summer. Just be aware that if it’s in a drought-prone area, it might need more water for a few weeks. Your seedling can be planted whenever nature permits! So long as the ground isn’t frozen, you can plant the plant even in December. Even if it is cold above ground, the roots will still grow and establish themselves perfectly well.
How long does it take to grow Echinacea from Seed?
Echinacea typically doesn’t bloom until the second year following seed germination. A huge perennial plant is echinacea. The first year, you often won’t have any flowers. On the ground, it will only resemble a big plant with leaves.
If you are fortunate enough to experience a bloom, it will often consist of a single stalk or flower and take place considerably later in the year than usual. But Echinacea will start to blossom in its second year. If planted in the full sun and well-drained soil, which are ideal circumstances for echinacea, you will be treated to a huge show in the plant’s third year of existence.
Purple coneflowers do they have seeds?
Plants of the purple coneflower thrive in arid or thin soil. Poor flowering and luxuriant foliage may be the results of rich or heavily modified soil.
Place purple coneflower where it will receive direct sunlight when planting. A day with full sun must include at least six hours of direct sunlight. The highest performance may be facilitated in more southern regions by morning sunlight, with late-afternoon shade preventing plant burns.
You can start purple coneflower plants from seeds or root division:
- Prevent the birds from eating all the seeds if you want to save purple coneflower plants for the following year. With the correct side facing up, place a brown paper bag over the seed head and let the seeds to fall into the bag. Professional growers think that while cultivating purple coneflowers, stratification (freezing) the seeds for a few weeks after they are sown in moist soil results in a more prolific bloom. People who live in regions with mild winters and summers might want to attempt this method. Another option is to naturally cool the seeds by sowing purple coneflower seeds in the fall in regions with cold winters.
- Division: Fall is a good time to start purple coneflower plants by dividing the roots. You should only divide plants that have been in the ground for three years or more. It’s possible that younger coneflower plants haven’t yet grown a root system that is sufficiently extensive for division. No more frequently than every three to four years should roots be divided.
Beginning gardeners can easily grow purple coneflower from seeds, and experienced gardeners love how simple it is to take care of coneflowers.
Can coneflower seeds be used?
Many gardeners like growing purple coneflowers. Botanically known as Echinacea purpurea, this perennial native to North America blooms in late summer with vivid magenta blossoms that attract bees and butterflies.
However, there are several cultivars and variations of this plant that produce blooms in a wide variety of hues, including white, yellow, orange, and red. The straight species is my particular favorite. There are numerous additional Echinacea species, and each one has its own distinct qualities.
Coneflowers in pots are frequently seen in neighborhood nurseries and garden centers, but if you have a sizable yard to cover with these vibrant perennials or if you enjoy a good gardening challenge, you could think about starting them from seed rather than buying plants. Coneflowers can be grown from seeds with the proper method. You can either save the seed from your own plants or a friend’s plants, or you can buy coneflower seeds from a variety of seed suppliers.
Once you have the seeds, you can try a few different techniques to boost the likelihood of success and the rate of seed germination.
Many diverse perennial seeds must undergo a procedure known as cold-moist stratification in order to emerge from dormancy. For the most part, many perennials have a tough seed coat and genetic programming that prevent the seeds from sprouting at the incorrect period (say, during a mid-winter warm spell). The seeds must be subjected to an extended period of cold temperatures and moist conditions in order to germinate.
Like many other perennials, coneflower seeds do not require this dormancy-breaking period of freezing temperatures in order to germinate, but treating the seeds with a cold-moist stratification will greatly increase the germination rates. Coneflower seeds have significantly higher germination rates after being exposed to 40 degrees F for around two months.
The first step is to combine the seeds with some damp sand, place the mixture in a plastic bag with a zipper cover, and refrigerate the bag for 8 to 10 weeks. Plant the seeds outdoors in the garden or indoors under grow lights when spring arrives.
The seeds can also be planted in potting soil-filled containers or flats, watered, and then covered with a clear plastic bag and stored in the refrigerator for 8 to 10 weeks. After the critical period has passed, remove the container from the refrigerator and place it in a room that is about 70 degrees under grow lights. Remove the plastic after approximately 10 to 14 days, when the seeds begin to sprout, and continue to care for the seedlings until they are big enough to be transplanted into the garden.
The last and most straightforward approach is to just scatter the seeds outside in the fall. Place the seeds where you want the mature plants to grow, then enclose the area with a small ring of fencing to prevent animals from discovering the seeds. The seeds will naturally be exposed to the proper temperatures for the appropriate amount of time, and when they are good and ready in the spring, they will germinate.
Coneflower seeds can be grown without being exposed to a cold-moist stratification, and you’ll probably achieve an OK rate of germination. However, by using these suggestions, 100% germination is a straightforward goal.

Coneflower deadheading is recommended.
Always use a clean pair of sharp pruning shears when pruning or deadheading any plant. Echinacea stems are too thick and coarse to be pinched and require a clean, precise snip with pruners, in contrast to many annuals and perennials that may simply be pinched back by snapping the spent flower head off. Before trimming, sanitize pruners in a solution of rubbing alcohol, bleach, and water to reduce the possibility of disease transmission from plant to plant.
Follow the stem from the blossoms down to the first set of leaves and cut just above these leaves to deadhead wasted blooms. In the event that the plant variety only produces one flower on each stem, you can also cut the stem all the way down to the plant’s crown. The majority of coneflowers have many flowers on each stem and will rebloom even without deadheading.
At leaf nodes, fresh blooms frequently develop before the top flower has finished wilting. In this situation, cut the stalk and spent flower back to the fresh blossoms. In order to prevent the plant from having strange-looking naked stems all over it, always clip the spent flower stem back to a set of leaves or a fresh flower bud.
Stop deadheading wasted blooms in the late summer or early fall so that birds can consume the seed throughout the fall and winter. Coneflower petals can also be used to prepare herbal drinks that fight off winter colds. You can also collect a handful of the fall blossoms to dry.
