Listed below are some tips for growing echinacea. These resilient perennial perennials are commonly known as coneflowers. They produce wonderful cut flowers and are very alluring to pollinators. When planted in large numbers, they look amazing.
Timing 8–10 weeks before planting outside, start seeds indoors. Echinacea may bloom in its first year if it is started indoors in the late winter. In the early spring or early fall, it can also be seeded directly. In 10 to 21 days, germination should take place.
Starting Seeds should only be sown 3 mm (1/8) deep. Provide complete darkness and a soil temperature of 21 to 25 C if beginning indoors (70-75F). Once sprouts start to appear, offer plenty of light.
Growing In any typical, well-drained, slightly acidic soil, space plants 30-38cm (12-15) apart. For optimal results, water plants frequently while trying to keep the leaves as dry as possible. Over the winter, keep seed heads whole to feed birds and protect important insects.

Quick Guide: Planting, Growing & Caring for Echinacea
- Plants that require little care and water have robust pink flowers.
- Plant in broad light; loves nutrient-rich soil, yet is remarkably adaptable
- Grow from division, nursery stock, or direct sowing
- attracts butterflies and bees
- Summer to October blooming; tolerates light frost
Full sun to some partial shade From seed to flower: 90–120 days of maturation 36 to 48 inches tall 12 to 24 inches should separate objects in all directions.
Site Preparation
Purple coneflowers are adaptable and can withstand most circumstances. Plants will grow, though, if you provide them with rich, well-drained soil and lots of sunlight. Before planting, the soil should be heavily amended with organic compost or aged animal dung to greatly increase the health of the plants (watch Flower Gardening from the Ground Upvideo). Coneflowers can withstand both heat and dryness.
How to Plant
It is simple to grow echinacea from seed, nursery stock, or division. In the open while a light frost is still possible, sow seeds 1/2 inch deep. Seed germination takes 10 to 20 days. If seeds are sowed early, flowers will usually blossom in their first year (see Summer Flowers for Color).
To prolong the blooming season, regularly pinch off spent blooms or utilize them as cuttings in flower arrangements. To encourage large, gorgeous blossoms, use a high-quality flower fertilizer multiple times during the planting season. Mulch reduces weed growth, retains moisture, and enhances aesthetics.
Insect & Disease Problems
Many garden pests, such as Japanese beetles, aphids, and leaf hoppers, are dangerous to echinacea. For a safe and sensible approach to pest control, check frequently and, if issues arise, take the following actions:
- To remove substitute hosts, remove weeds and other garden trash.
- Put seriously afflicted plants in the garbage after bagging them up safely.
- To combat and eliminate insect pests, release beneficial insects that are readily available.
Is it difficult to grow Echinacea from seed?
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.
Before planting, should I soak the echinacea seeds?
Both sides of my shady front-yard path are adorned with columbines. The small group of people on one side were purchased as plants from a catalog, whereas I raised the people on the other side from a handful of shiny, black seeds to a swath of long-spurred blossoms. Guess which ones make me feel the happiest? Starting seeds gives me benefits other than maternal pride. A package of seeds can produce 20 or more plants for the price of one potted plant, so I’ve also got a greener thumb and a bigger wallet. Study more: 8 Garden Center Money-Saving Strategies
For the best results, consider the plant’s natural habitat
A lot of seeds are easy to grow. You just need to rake up some loose soil and disperse the seeds. Other seeds, however, will do better in more regulated environments or with special care that simulates the environment of their natural habitats.
For example, following a time of damp cooling in a dark environment, many plants whose original habitats have cold winters sprout most easily. Winter gives them what they need in the wild. If the seeds germinated in the late summer or fall only to die from the cold of winter, it would be a waste of energy and quite anti-Darwinian. Instead, they endure the harsh winter. The seed coverings relax during the seeds’ profound sleep, and when springtime warmth and moisture arrive, they burst into growth.
Other seeds, particularly those that live in deserts, may only need a brief period of rain (or manufactured rain, often known as the garden hose or a good overnight soak) to completely open their seed coats.
To get the most out of hot-climate wildflowers, though, may require more drastic measures. Fire may be the decisive factor in the Southwest. Texas bluebonnets (Lupinus texensis) were very difficult for me to grow until one year when a kitchen fire burnt an envelope of seeds. I threw the burned seeds onto the bank, thinking that was the last of them. Naturally, each and every one of them grew into a strong, healthy plant.
How do you determine which seed need which? Start by reading the package. The amount of information that is crammed into a seed packet’s back is comparable to having an encyclopedia of plants at your disposal. Planting dates, duration until bloom, guidelines, and specific requirements Even if you have to use a magnifying glass to read it, everything is there.
Commercially obtained seeds are not exposed to the natural cycle of the seasons—cold, hot, and rainy—and they may need to be coaxed into growing. Here are three quick tricks that can trick almost any reluctant seed.
Speed sprouting by presoaking seeds
The key to my success with seed starting is presoaking. The seed embryo is exposed to moisture during this straightforward process, which is the main driver of growth. I add seeds to hot tap water that has been poured into a shallow container, spread them out, and let them stand for up to 24 hours. If the seeds are soaked for too long, they may rot. Water seeps through the seed coat, causing the seeds to enlarge as the embryo inside grows larger.
I presoak almost everything, with the exception of the smallest seeds. But I usually take care to wait until the night before planting my seeds in containers or the garden to presoak them. Once the seeds have swollen, immediately plant them in damp soil and continue to water them until they are up and growing. This easy method can cut the typical germination time by several days.
The titles of the other two methods, stratification and scarification, are so intimidating that many gardeners avoid using them because they are occasionally required to break the dormancy of obstinate seeds. But these are just fancy phrases for straightforward methods.
Some seeds need moist cold; others need nicking
“Stratification is the process of deceiving seeds into believing that it is winter by providing a time of moist cold. Pre-soaking the seeds before placing them in a sandwich-size, zip-top plastic bag with damp seed-starting material halfway inside can help the seeds germinate indoors in the spring. Place the bag in a quiet area of the refrigerator after adding another inch of wet medium to the top of the seeds (at 34F to 41F). Weekly checks for germination are recommended. When the seeds start to form roots, delicately move them into pots by carefully taking each seedling out of the bag with a spoon to keep dirt around the new roots and prevent upsetting delicate new growth. After that, treat them like any other seedling.
Cold-treated seeds can also be sown outside in the fall or kept in a refrigerator through the fall and winter, then sown in pots and started indoors or outdoors in the spring. For fall or winter outdoor seed starting, put the seeds in pots as usual, but cover the top of each pot with a thin layer of very fine gravel to prevent soil erosion from rain. It works nicely with washed, naturally colored (undyed) aquarium gravel. Make a level layer of damp sand wherever you plan to overwinter the pots—in a cold frame or against a garage wall. Keep the pots close together and bury them to the rims. They are protected from extreme cold and kept from toppling over and spilling thanks to this. Move the pots to a protected nursery location once the seeds have begun to sprout.
The third method, “Scarification is the process of nicking the seed coat with a knife or piece of sandpaper to allow moisture to enter the seed’s embryo. I use the knife if a seed is large and I can’t dent it with a fingernail. It is best to use a rat-tail file or a small, sharp pocketknife blade. Avoid being overly aggressive; only a very small piece or slice of the seed coat needs to be removed. The seed coats can also be worn away by lining a jar with a sheet of sandpaper that has been trimmed to fit, screwing on the lid and shaking the jar like a maraca. Just before planting, scarify the seeds. Long-before-planting seeds run the risk of drying out and becoming useless when they finally get to the soil.
It’s easy to care for seeds planted in pots
I usually start the majority of my seeds in pots, especially slow-growing perennials and annuals. The seedlings are easier to take care of, and weeding is not necessary. A slow-growing plant can be identified by looking at the seed packet. You have a slow starter if it suggests beginning the seeds inside 8 to 10 weeks before the last date of frost.
According to conventional wisdom, seeds should be sown densely in a flat or tray, and then individual seedlings should be “prick out for repotting into larger pots.” However, I favor starting a small number of seeds in pots that are at least 21/4 inches in diameter in order to completely avoid transplanting. I either put the entire cluster in the garden or use scissors to thin the seedlings as they emerge.
Soilless mixes help prevent seedling disease
I use a commercial “soilless seed-starting mix,” which is a combination of sterilized materials like vermiculite and milled sphagnum moss. I rarely experience damping-off disease, a fungus that kills seedlings by causing them to wither and wilt. I transfer all but a little amount of the mixture into a big bowl and thoroughly saturate it with warm water before planting. After that, I gently load the medium into the plastic pots I collected from my previous periodic nursery shopping sprees into the containers to a depth of 1/2 inch below the rim. Prior to sterilization, used containers should be cleaned by soaking in a solution of one part bleach to nine parts water.
When the pots are ready, I carefully shake three or four seeds into each one, leaving at least a half-inch between each one, and snip off a corner of the seed packet (or its inner glassine envelope of seeds). Small pieces of stiff white paper are folded in half, seeds are poured into the strip, and then the paper strip is lightly tapped to distribute the seeds. This method gives me better control because the smallest seeds can slide out too rapidly. If the seeds are big enough to see, I gently press each one into the moist, soilless mix with my fingers, making sure it’s dry to prevent seeds from sticking to it. I cover the seeds with a thin layer of the saved seed-starting mix using a sieve rather than burying them. I don’t cover seeds at all if they need sunshine to germinate. I then write a label with the name of the plant and the date on it, pushing the marker into the pot so that it is flush with the edge.
I cover the pots with a sheet of plastic wrap, glass, or clear plastic to maintain moisture if I anticipate the seeds to germinate in a few days or weeks, and I check on them every day. I take off the covering once sprouts start to show. I start a lot of seeds; I’m not concerned about giving them bottom heat to hasten germination; I just want to make things straightforward. I don’t bother covering them if the seeds are going to take a while to germinate—some stratified seeds may spend months in a pot before sprouting—and just take extra care to keep the soil moist.
I place the pots on a cookie sheet or another shallow tray after they have been planted so that they may be moved to a cold frame or another area for seed-starting with ease. The trays also make it simpler to water the bottom. Keep the seed-starting material moist to promote faster germination; I either mist the pots from above with a very fine mist or pour water into the tray and allow the pots soak it up from the bottom.
Young sprouts need light and a little fertilizer
I set trays of pots on windowsills that face south or east because seedlings require light. The windowsill space may be taken before all the pots are set down because I’ve begun as many as 800 pots of seedlings in a season. In such case, I retreat to the basement or somewhere else inside, where I rig fluorescent tubes for shop lights. Although some books suggest fluorescent tubes that emit particular types of light, regular, reasonably priced fluorescent tubes also function well. I install the lights on chains so they can be readily raised or lowered in order to keep the light source near to the plants. For 12 to 16 hours per day, seedlings require artificial light. For young seedlings, indoor temperatures in the mid-sixties are suitable. Warmer temperatures are also acceptable. I don’t bother about adding extra light or worrying about the temperature if I’ve planted the seeds in pots outside in or out of a cold frame.
I use a water-soluble fertilizer once a week to promote growth after seedlings appear. Any fertilizer will work, including fish emulsion, but I prefer to use Peters or Miracle Gro. I mix at the ratio suggested for container plants if the package does not specify a strength for seedlings. When instructions call for “inside plants” or “outdoor plants,” I go with the advice for indoor plants. I reduce the fertilizer dosage in half if it is solely advised for outdoor usage. That works up to roughly 1 teaspoon per gallon of water for my preferred fertilizers.
Toughen up seedlings, then plant them in the garden
The seedlings are prepared to be planted in the garden as soon as they have two or three pairs of genuine leaves. However, spoiled seedlings need to become more resilient before they are released into the broad world. The goal is to progressively accustom indoor-raised plants to the challenges of outside existence. Tender plant tissues may be harmed by the unexpected impacts of sun, wind, and weather without this phase, known as “hardening off.
Start by taking the seedlings outside and placing them in a wind- and shade-protected area for no more than a few hours on the first day. If that’s the exposure they’ll eventually be planted in, gradually extend the duration of the plants’ outside stays and relocate the plants to a more sunny location. The plants should be prepared to be planted in the ground after about a week. A cloudy, dreary day is ideal for planting because the seedlings will be protected from the sun’s drying effects and the dampness will hasten their establishment. Plant late in the day if the weather is uncooperative so that seedlings can emerge in the cool of the evening.
Before transplanting your plants, give them plenty of water. Also, irrigate your garden soil until it is moist but not drenched. Slide the plants out of the containers and position them where you want them. Then, use your fingers to compact the soil around each plant and spritz it with water. As soon as the plants begin to grow nicely, make sure to keep the soil moist.
Make a seedbed for sowing seeds in the garden
The majority of annuals and perennials that bloom right away after seeding are simple to grow from seeds placed directly in the yard. They develop quickly and sprout quickly, saving you time from having to sort between tiny flower seedlings from hefty weed seeds. I grow plants in pots if they can’t survive till I get around to pulling weeds.
After deciding on a location that will meet the needs of the plant, remove any existing vegetation and loosen the soil to a depth of at least one shovel. Spread a 2- to 4-inch layer of organic matter, such as old manure or compost, over the loose soil and hoe it in thoroughly to create a light, moisture-retentive soil texture. By hand-raking the surface to a fine texture, you can remove any lumps. Use hand tools to create a shallow seedbed that won’t disrupt the roots of nearby plants if you’re planting annuals or biennials among established species in a perennial garden.
Directly scatter seeds over the prepared soil. Be sparing: attempt to space little seeds at least 14 inches apart, and larger seeds, such as nasturtium (Tropaeolum majus) or purple coneflower (Echinacea purpurea), 1/2 to 1 inch apart. Next, rake some soil over the seedbed to create a thin layer. Simply dispense a few handfuls of fine dirt over the seeds in confined locations. The seedbeds should be marked with weatherproof labels. Lastly, water that is lightly misted. While the seeds germinate and until the seedlings are established, it is imperative to maintain wet soil.
