Echinacea, also known as the purple coneflower (Echinacea purpurea), is one of the greatest flowers found in the prairies of America. With their substantial daisy-like flowers, these hardy perennials are a stunning and water-conserving option for borders, native-grass lawns, and xeric gardens.
Echinacea is a cottage garden classic that produces a stunning display of color, particularly when placed amid shorter perennials where the brilliant, purple, pink, and white blooms shine above other foliage. From July through September, plants put on a lot of blooms that are attractive to both pollinators and butterflies. The height of this hardy, attractive perennial is between three and four feet.
Fun fact: Echinacea is a well-known remedy for colds and flu that strengthens the immune system.
Do cone flowers grow throughout the summer?
Since they bloom frequently, you can prolong the blooming season by deadheading (removing the spent flowers from living plants). Each flower blooms at the top of the stalk and continues to bloom for a few weeks.
Self-seeding
Coneflowers reproduce by seeding themselves. Each flower contains petals and a center cone. Each petal has a seed affixed to the base where it links to the cone, and the cone produces many seeds (this is called a ray flower). Many seeds are produced by each bloom, some of which will unavoidably fall to the ground. Particularly Goldfinches will land on dried seed heads and gather the seeds. If a mouse or another bird doesn’t eat the seeds that fall to the ground during this procedure, they can germinate the following Spring.
Coneflowers will grow in numbers if the soil is disturbed and there is an abundance of seed that falls from the wasted flower.
Root Mass
Due to their fibrous root systems, this only applies to the common Purple Coneflower, Echinacea purpurea, and its hybrids. Each year, a coneflower’s center root mass expands in size, finally reaching a diameter of 2′. To keep the plant healthy and appealing, divide the coneflower root mass once it reaches this size. The issue is that the center of the root mass will die, leaving a hole in the plant’s center for the upcoming growing season.
Coneflowers reappear every year, right?
- 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.
Coneflower flowers last for how long?
For nearly two months, coneflowers bloom, bringing birds and butterflies to the yard. The domed seedheads remain tall throughout the winter after the flowers have faded. Snow draws a warm tiny cap on each seedhead as chickadees and goldfinches hover lightly on top to eat the seeds. Cut back the old flower stems in the early spring to make way for a new season of vibrant, long-lasting perennial blooms.
Coneflowers can they spread?
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.
Coneflowers: Should I deadhead them?
Coneflowers can also be pruned in the summer. Pruning, meanwhile, does not appear the same in the summer as it does in the spring or fall. When you prune in the summer, it is more akin to “dead heading” and bouquet-making trimming. Unlike in the fall or spring, you won’t want to completely prune your plant.
In order to deadhead your coneflowers in the summer, you must remove bloom-expiring flowers. Deadheading is frequently done to maintain the plant’s appearance, stop seed production, and promote new blooms on the plant.
Did you know that cutting the flowers will increase the amount of blooming in many coneflower species? It’s true that cutting your flowers to enjoy indoors can frequently lead to even more blooms all summer long. So pull out the scissors and enjoy the lovely blooms both inside and outside.
In front of coneflowers, what should I plant?
A rayed blossom with a width of 2 to 4 inches (5 to 10 cm) is produced by echinacea. Consider different blooming plants as well as foliage queens when deciding what to put alongside coneflowers to enhance their appeal. Use of all native plants as Echinacea’s partners in a garden is another idea to take into account. Eastern and central North America are where echinacea is originally from. These hardy American Department of Agriculture plant zones 3 to 9 easy bloomers are.
The perennial garden is ideal for native plants. Since they are native, they can easily adapt to the environment and don’t need as much maintenance as introduced species. The native plant butterfly weed, also known as Asclepias, is a great companion for Echinacea. It does draw butterflies and has vivid orange blooms.
The gaillardia has all the hues of a sunset, whilst the black-eyed susan delivers a bright yellow blossom with similar rays. While hardy geraniums produce a carpet of jewel tones and are a wonderful base plant in the bed, lupines come in a variety of tones and are an early season color.
How are coneflowers prepared for winter?
Due to their hardiness, coneflowers are among the easiest perennials to care for throughout the winter. The only thing left to do is watch them resurrect in the summer rather than pruning them back in the fall or spring.
- Decide whether to prune your coneflowers in the spring or the fall. Either method works, but leaving them up over the winter gives nearby birds access to seeds.
- Cut your coneflowers back 3-6 inches from the ground if you decide to prune them in the fall.
- Coneflowers planted in the ground should only be watered during unusually dry winters. Every other week, or as soon as the top few inches of soil feel dry to the touch, lightly water potted coneflowers.
- Coneflowers should be pruned down 3-6 inches from the ground in the early spring if you leave them up during the winter.

Can coneflowers survive in the shade?
Coneflowers can flourish in some shade. Although they enjoy and thrive in the sun, you may still grow them in a gloomy yard, as I do. All you need to do is make sure your echinacea receives three to six hours of direct sunlight every day, preferably in the morning and early afternoon.
Coneflowers require how much water?
These low-maintenance perennials just need the bare minimum: frequent watering of approximately one inch per week, a small spring compost addition, and fall pruning, though even that is optional if you like to leave the seed heads.
Pruning: Many modern cultivars are flower factories and will continue to produce without needing to snip off spent blooms, even though deadheading is a standard gardening practice to promote recurrent flowering. In this manner, you may simply leave the seeds alone, providing food for yet another favored group of wild birds, especially tiny songbirds like goldfinches that are particularly fond of the seeds. Why not just let the early, larger flowers go to seed and provide the birds with a feast? Post-deadheading blossoms can be smaller and less gratifying.
Once your coneflower’s flowering is done, you can trim it to the ground so that it can survive the winter. Or, you can chop it down in the first few weeks of spring if you’d rather leave the dry seed heads.
If the flowers are little or poorly developed, add some compost to the soil surrounding the plants as an amendment and fertilizer. Be cautious because excessive feeding might result in a surplus of foliage and a dearth of blossoms.
Watering: Tolerates drought, but thrives under conditions of normal to low rainfall. Water often, but allow the soil to dry out in between. Every week, coneflowers require at least one inch of water.
Divide clumps when they become crowded, roughly every 4 years. If you leave spent blooms in tact, they will easily reseed themselves. If they start to get out of control, deadheading can assist. Some gardeners strike a balance by gathering the seeds and planting them in strategically chosen locations for the following season.
Diseases and pests: Aster yellows, a virus-like illness brought on by a phytoplasma, is one issue that should be noted with Echinacea. Deformed flowers, occasionally with strange tufts in the cones, and yellow leaves with green veins are symptoms. Leafhoppers and other sap-sucking insects disseminate the bacterium (and can also be spread on pruners during deadheading). Once you realize a plant is diseased, dig it up right away and discard it because there is no treatment. Leaf miners, powdery mildew, bacterial spots, gray mold, vine weevils, and Japanese beetles can all plague them.
