Despite the fact that the majority of us would want to spend the entire day in our gardens, real life interferes. Instead, we choose simple, low-maintenance plants that, despite only requiring a few minutes here and there of care, give the impression that we spent hours in the garden. Coneflower is a plant that I frequently recommend since it can withstand poor soil, extreme heat, drought, full sun to part shade, and it blooms continually whether you deadhead it or not.
Aren’t coneflowers sounding quite good right now? Getting better Echinacea attracts and feeds pollinators and a variety of butterflies when it is in bloom (such as Fritillaries, Swallowtails, Skippers, Viceroy, Red Admiral, American Lady, Painted Lady, and Silvery Checkerspot).
After they stop blooming, their seed-covered “cones serve as a valuable source of food for many birds from late summer to winter (such as goldfinches, chickadees, blue jays, cardinals, and pine siskins). Therefore, when people ask me about deadheading Echinacea plants, I normally advise them to only do it during the flowering period in order to keep the plant looking lovely, but to leave fallen flowers in the late summer to early winter for the birds.
In order to stop Echinacea from reseeding itself all over the garden, you can also deadhead it. Older forms of coneflower can self-seed, though not quite as aggressively as Rudbeckia. Newer hybrids typically do not self-sow and do not generate viable seed. Birds aren’t really interested in these more recent hybrids either.
Coneflowers can they self-replicate?
I’ve cultivated countless coneflowers of various types over the years. I now fully understand how coneflowers proliferate and how to handle them. So let me share what I’ve discovered with you.
Coneflowers reproduce through self-seeding and developing a deeper root system. Coneflowers do not, however, spread their roots and take over gardens (rhizomes). Each Spring, a coneflower plant may produce several seedlings, and its root mass may enlarge by one to two diameters. However, it won’t produce runner roots.

Coneflowers return every year in what way?
Yes, because echinacea is such a prolific self-seeder, it will come back every year and frequently in the most unexpected places.
The perennial echinacea is resilient and can withstand extremely chilly winters. Plants go dormant in the winter and reappear in the spring; you should prune them back at this time for the summer.
An important component of the appeal of these perennial favorites is the ease with which they can be grown.
How can you encourage coneflowers to grow?
Echinacea needs full to partial sun to grow well. At least four hours of sunlight every day are required for plants. Since the plants are native to woodland borders, they will flourish in locations with morning shade and afternoon light, or the opposite.
Echinacea may thrive in rocky, poor soil, but not in soggy, waterlogged soil. Compost should be used as a mulch around newly planted plants.
Coneflowers grow in clumps and require space. One plant will typically grow bigger, but it won’t spread through roots or rhizomes and take over the entire garden. Check the mature size stated in the plant description to help you choose the appropriate spacing because the final size of the plant clump depends on the cultivar. Leave 18 inches between plants if it is anticipated that they will spread to be 18 inches broad. Echinacea must be planted where you want them since they have deep taproots. They dislike being relocated after being established.
Echinacea plants should be planted in well-drained soil in full to part sun in the spring or the fall. Echinacea is also simple to cultivate from seed, but it needs a period of stratification—a cold, damp time—in order to germinate. In the fall, scatter seeds widely (after hard frost in the north and prior to winter rains elsewhere), lightly covering them to deter birds from eating them. In the spring, seeds will begin to sprout. One benefit of starting with transplants is that the majority of plants will bloom during the second year.
Do cornflowers grow back?
Response: It’s unlikely. Mulch should be put in a thick layer of 2 to 3 inches for best results. Coneflower seeds will not germinate because the mulch’s primary function is to stop weed seeds from sprouting.
No, cornflowers are an annual plant. They reproduce through seed. Allow your cornflowers to go to seed when they bloom. The seed can then be saved and planted the following spring, or you can let it naturally fall into the garden. In the spring, they will begin to sprout.
No, since they are perennials, purple coneflowers only bloom once a year. After you pick the dead flowers, no new blooms will appear until the following year. The good thing about coneflowers is that their flowers last considerably longer than the blossoms of other perennial flowers, which often only persist for two weeks.
Is it preferable to sprout commercial seeds indoors or can they be sown directly into the ground? Is spring or autumn the ideal time to plant seeds?
In order for echinacea seeds to germinate, you must sow them outside in the fall. You must cold stratify seeds in your refrigerator to simulate cold conditions if you wish to start them indoors.
Coneflowers are perennials, thus the answer is yes. Frost kills the foliage in the fall, but the roots survive the winter in the soil. New foliage will start to sprout from the roots in the spring as the soil begins to warm up.
Will the coneflower (in this example, orange) return back the same color if I don’t deadhead it in the spring, or will the seed turn back into the original purple flower?
The quick answer to your query is that because orange coneflowers are hybrids, the children they produce in your garden might not be either the original purple or orange.
A longer explanation: depending on how the genes are expressed, hybrids are the offspring of two parents who may or may not appear alike. For instance, you will have orange offspring if both of your parents carry the recessive gene for orange. However, no offspring will be orange if just one parent carries the recessive orange gene.
A hybrid cross will result in progeny that will carry seeds that may or may not germinate. Many hybrids are unfertile. Depending on how the genes are expressed, some seeds will grow into plants that do not resemble their hybrid parents or even their grandparents.
I’ve grown purple coneflowers all around, including in areas where there are lots of rabbits, but I’ve never had an issue with them being eaten or destroyed by rabbits.
Should coneflowers be deadheaded?
- Before cutting down to the ground to get ready for fresh growth in the spring, let plants stand through the winter to provide food for wildlife.
Coneflowers are a must-grow if you appreciate watching pollinators buzz and flit about lovely, trouble-free flowers that bloom for a long time. Although purple coneflowers (Echinacea purpurea) are the most prevalent, there are many new coneflower cultivars available in a rainbow of cheery hues, including pink, yellow, orange, red, and white. These flowers don’t just provide joy for a short time; they return year after year because they are perennials.
Because of the “cone that starts to poke up in the center of the circle of petals as each flower matures, coneflowers get their name. Actually, this is a group of seed heads that, when allowed to dry on the plant, serve as Mother Nature’s bird feeder, luring a large number of cardinals, goldfinches, and other hungry birds.
How to Choose Coneflowers
Which of the dozens of different coneflower kinds should you grow? The quickest response is: whichever ones you deem attractive and have room for (check the plant tag for info on this). Want some recommendations? Use these
- There are numerous native coneflower species, but the purple coneflower, which typically reaches heights of 2 to 4 feet, is the most well-known.
- ‘White Swan’ is a well-known variety that grows up to 4 feet tall and has big white blossoms among other widely available types.
- A lot of dwarf coneflower types, like “Kim’s Knee High,” remain fairly compact (with pinkish-purple flowers). If you have a small garden, consider planting them because you will get many blossoms in a short amount of space.
- Coneflower variants are also available that hardly resemble coneflowers at all, notably hybrid double types with two rows of petals. Just be mindful that some of plants produce flowers that fade more quickly than others in the garden.
Where to Plant Coneflowers
Coneflowers should be planted in an area with at least 6 to 8 hours of sunlight per day. However, in warmer climates (zones 8 and higher), a little midday shadow is beneficial because it will prevent the blooms from fading. As a result of their clump-forming nature, these plants won’t spread as widely as some other perennials. If you leave blossoms in situ, many of the older kinds may self-seed, which is a simple way to grow new plants!
When to Plant Coneflowers
Coneflowers grow best in the spring, after all threat of frost has passed. You can plant in the early fall as well. Just make sure your new plants have at least 6 weeks before the first anticipated frost to form roots; otherwise, they might not reappear in the spring.
How to Prepare the Soil for Planting Coneflowers
Coneflower roots need a healthy environment to flourish, so strengthen your natural in-ground soil by adding 3 inches of Miracle-Gro Garden Soil for Flowers to the top 6 inches of soil. The Moisture Control technology in this nutrient-rich garden soil helps to safeguard plants when they unintentionally receive too much or too little water. Additionally, if you use Miracle-Gro soil and plant food (and adhere to all instructions), you’ll get up to three times as many blossoms during the growing season (compared to unfed), so be sure to read the part below on “How to Feed Coneflowers.” Just one coneflower planted? Make a hole, then mix garden soil and the recently excavated earth 50:50.
How to Plant Coneflowers
1. Determine the location where you’ll plant your coneflowers, making sure to allow enough room between each plant. (The plant tag ought should indicate how much room you need.)
2. Create a hole for each plant that is identical in depth and width to the root ball.
3. To give root growth a boost for the first 30 days, drop a Miracle-Gro Quick Start Planting Tablet into the planting hole (as per the instructions on the label).
4. Remove a coneflower plant from its pot and insert it into the gap. The top of the root ball should be level with the surrounding soil.
5. Fill in the area surrounding the plant and firm up the dirt there.
6. Water sources.
7. Spread a 3-inch layer of mulch around the plant, being careful not to let it contact the stem, to help keep the soil moist and to block sunlight so weeds can’t develop.
How to Stake Coneflowers
Coneflowers rarely need to be staked because of their sturdy branches and large flowerheads. However, if you do encounter floppy plants, drive a strong stake close to the middle of the plant (avoid going through the plant), and then loosely wrap twine around the stake and the individual stems. Or, you might spend money on a spherical flower clumping stake. In either case, the finished product should appear natural, not constricted around the plant’s middle.
How to Water Coneflowers
Coneflowers can tolerate drought pretty well once they’ve had some time to establish themselves. Check on them every other day after planting; if the top inch of soil is dry, thoroughly water. Your coneflowers’ droopy leaves are another indication that they need water. Coneflowers shouldn’t require watering after a full growth season in the garden unless it hasn’t rained in at least two months.
How to Feed Coneflowers
Want a ton of lovely flowers? As soon as fresh leaves begin to grow in the spring, begin feeding your coneflowers Miracle-Gro Water Soluble Bloom Booster Plant Food. Your plants will grow bigger and produce more blooms as a result of this flower feast, which gets to work right away. Additionally, since you may apply water-soluble fertilizer when watering, it won’t require any extra time to do so.
How to Deadhead and Prune Coneflowers
Deadhead coneflowers frequently at the start of the bloom season to promote greater flowering by removing the faded blossoms before they set seed. Always prune back to a leaf or section of the stem where a new bud is visible. You can just leave them alone later in the season when the plant starts to produce fewer blooms.
To feed the birds over the winter, let the plants alone. Prune them to the ground in late winter. In the early spring, leaves will appear at ground level, soon to be followed by flower stalks.
Try this simple trimming tip to prolong the blooming period of your plants’ coneflowers by at least a season. Cut back some of the stems by half as they start to grow again in the spring to postpone flowering on those stalks. The cut stems will lend their beauty a bit later in the season after the uncut stems have finished blooming.
Can I Divide Coneflowers?
Coneflowers don’t require dividing like some perennials do in order to thrive. They are difficult to divide because each plant has a single taproot. Therefore, simply let them be.
Cornflowers self-seed, right?
Don’t forget about flowers either; biennials like foxgloves, honesty, and teasel are all hardy self-seeders that wildlife also enjoys. Annuals like cornflowers (bachelor’s buttons), calendula, nasturtiums, and poached egg plant are also excellent self-seeders.
Should coneflowers be pruned?
Coneflowers benefit from being pruned since it revitalizes the plant, making it an essential maintenance chore. It promotes sprouting, more blooms, and protects the plant from appearing overcrowded or messy. All gardeners must prune because it maintains the health and beauty of their plants and gardens.
Coneflowers should be divided, right?
Coneflowers are best moved or transplanted in the early spring, when the earth is just starting to warm up and soften. In the early fall, when temperatures are cooler and the sun is not as intense as it is in the summer, they can also be transplanted. Coneflower transplanting should not be done in the summer.
After allowing them to mature for around three or four years, you can divide your coneflowers and transfer them. Or, you can frequently transfer a whole plant from one location in your yard to another. You should have no trouble replanting your coneflowers as long as you take care to do it at the appropriate time of year and are able to obtain enough of the healthy root system for a successful transplant.
Coneflowers generally tolerate drought because of their extensive tap roots. The roots of Echinacea purpurea have been found to extend five feet deep! Coneflowers should be divided and transplanted after being dug up as deeply as possible to preserve as much of the root system as possible. Although you won’t be able to collect the entire root system, your transplant should be fine as long as you can get around a foot of root development.
Once you have separated and prepared to transplant your coneflower plant, proceed as instructed in the “Steps to Plant Coneflowers” section above.
