Purple coneflower (Echinacea purpurea): Wild and Amazing

Coneflowers, or echinacea, are natural wildflowers of America that are adored by songbirds, bees, and butterflies. Echinacea purpurea, sometimes known as Purple Coneflower, is a well-liked perennial that produces an abundance of huge, daisy-like purple coneflowers that measure 5 inches (12 cm) across during the summer. The striking, long-lasting flowers are carried on sturdy, upright stalks covered in rough, dark green, lance-shaped leaves. They have a dark brown, spiky center cone surrounded by purple, drooping rays. Their abundance of nectar draws hummingbirds and butterflies. Birds that eat seeds will visit the blackened cones if the flower heads are left on in the fall.

SpeciesEchinacea purpurea

Habitat and Distribution of Purple Coneflower

  • Echinacea purpurea originates in northeast Texas, Missouri, and Michigan and spreads eastward throughout the Great Plains bioregion. Purple coneflowers thrive in rocky prairies and open, forested areas. 
  • Purple coneflowers usually grow beside roadsides, in meadows, and open woodlands.
  • They are frequently found in locations with full sun to light shade and prefer well-drained soils.
  • It is well known that these plants can withstand a variety of soil conditions, such as sandy, loam, and clay soils.

Anatomy and Morphology of Purple Coneflower (Echinacea purpurea)

  • The plant has rigid stems that are upright, stoutly branched, and glabrous. The leaves are oblong to ovate lanceolate, with an acute apex and serrated edges.
  • Basal Lower stem leaves have decreasing petioles as one rises up.
  • The petioles are short and somewhat winged.
  • The leaves have a dark green top surface and few white trichomes.
  • The blooms form inflorescences that range from crateriform to hemispherical and end in peduncles.
  • The corollas are dark purple, pinkish, or reddish, and can be linear, elliptic, or obovate.
  • The center cone is thorny. The ray florets are tall and droop down.
  • Cypselae fruits are three or four-angled, tan or bicolored, and have a dark brown band distally.
  • As the bloom matures, the center cone (achene) becomes increasingly pointed and thorny, resulting in yellowish brown seeds that germinate unevenly after 10-21 days.

How to Grow and Care Purple Coneflower

Light: Coneflowers require direct sunlight and cannot tolerate partial shade. If placed in too much shade, they become lanky and flop. Plants are also more susceptible to foliar diseases, such as powdery mildew, when grown in the shadow.

Soil and Water: Coneflowers are not picky about soil type; they can thrive in sandy, rocky, and clay soil with a neutral pH (6.5 to 7.0). They dislike wet feet, therefore proper drainage is essential. Purple coneflower, which grows native to grass prairies, prefers well-drained soil. Established plants endure drought well, though they will blossom more if watered often during dry spells.

Temperature and humidity: Coneflowers can tolerate a broad variety of temperatures, from subzero winters in zone 3 to hot summers in zone 9. Summers that are hot and dry are not problematic. However, high humidity is not desirable.

Fertilizer: If the coneflowers are planted on soil that has been treated with organic matter, fertilizer should be limited to dusting a couple of handfuls of compost around each plant in the spring. Excessive fertilizing might result in leggy plants.

Pruning: Once the plants have done blooming, remove the spent blossoms to encourage another wave of blooms.

How To Propagate Purple Coneflower

Purple coneflower and other Echinacea species are most typically reproduced in the home garden through root division. They are also easily cultivated from seeds. Those who appreciate a challenge in gardening may want to experiment with root cuttings.
Purple coneflowers produced from seed may not flower in the first year, but some do. Plants propagated from root cuttings usually bloom in their first year.

Whatever way you use, adding more of these long-blooming garden stars to your yard is well worth the effort. It is really easy to cultivate; all it need is full sunlight and well-drained soil.

Propagate coneflowers with root cuttings

  • Gently lift the soil around the plant’s base to expose the roots.
  • Trim off portions of root that are at least as thick as a pencil. Cut them into 3 inch-long pieces.
  • Return your original plant to its home.
  • Plant each root cutting in a 4-inch pot filled with compost, coir, or perlite. A combination of moist sand, compost, and perlite can also suffice. If you already have a preferred combination for rooting other cuttings, that is ideal.\
  • Cover with about a half-inch of potting material and wet the soil. Put the pots in a warm location. Label them so you do not forget.
  • New shoots may take up to six weeks to emerge from the surface. Once they do, keep growing your young coneflowers until they’re big enough to plant out.
  • If the season does not allow for outside planting, you may elect to upgrade to a 6-inch pot and grow them larger.

Grow Echinacea from Seeds

  • Echinacea is easy to grow from seed, and seed firms provide a wide variety of varieties. If you already have a natural variety of coneflowers in your garden, you can try preserving its seeds as well.
  • Prepare the seed trays. Use any seed starting mix that is well-drained. If in doubt, use some perlite.
  • Sow one to two seeds each cell. Using a blunt pencil, leave a minor mark on the surface to determine if you dropped a tiny seed or not.
  • Echinacea seeds require sunshine to sprout, so do not hide them. A light covering is ideal.
  • Mist the surface, cover with a humidity dome or plastic wrap, and store in a bright, warm environment.

Propagate Purple Coneflower Plants by Division

This is the simplest and most usual approach for propagating coneflower plants. Echinacea purpurea has a large, fibrous root system that is easily dug up and divided; in fact, it should be divided every few years to avoid becoming root-bound and decreasing.

  • Gently dig around the base of the plant to release the root system. Try to preserve it as a single unbroken ball. Get as deep as your spade can go.
  • Carefully extract the root ball from the hole.
  • Cut the root ball in half with a soil knife, large old kitchen knife, garden spade, or machete, leaving a decent number of sprouts on each piece. If your root ball is huge, you may be able to divide it in thirds.
  • Transplant these new plant-root pieces to their new location in the garden, using the same depth as previously.
  • Give your new coneflowers plenty of attention over the first few months. They were drought-tolerant until they were dug up with a fully formed root system. However, they will require some assistance until they are established.

Potting and Repotting Purple Coneflower

  • Make sure the soil in the new area is well prepared with compost, well-drained, and amended if necessary.
  • To allow the purple coneflower’s roots to grow, dig a hole that is at least twice the width of the root ball and somewhat deeper.
  • Gently remove the purple coneflower from its original place
  • Place the purple coneflower plant in the center of the hole, with the top of the root ball level with the surrounding dirt or slightly higher.
  • Backfill the hole with the removed dirt, gently firming it around the root ball to eliminate air pockets.
  • Water the purple coneflower thoroughly to settle the soil and provide proper root-to-soil contact.
  • If necessary, add a stake or support for the purple coneflower to ensure that it grows erect and sturdy.

Benefits/Uses of Purple Coneflower

Echinacea plants contain a variety of bioactive chemicals, including: Alkamides (also called alkylamides), Glycoproteins, Polysaccharides, Antioxidants. These chemicals are thought to give a variety of health benefits: Anti-inflammatory, immunomodulatory (altering the immune system), Anxiolytic (anxiety reducer), Antimicrobial.

Health Benefits of Purple Coneflower

Common cold: Echinacea is probably best known for its use in treating the common cold.

Despite its popularity, research results have been varied, and there is no conclusive proof that echinacea helps patients with colds. A 2014 analysis examined more than 20 research with over 4,000 participants on various types of echinacea to determine whether any were beneficial for the common cold. Researchers discovered that echinacea was more successful than a placebo (an deliberately inefficient medication provided to a control group) in curing a cold. However, no echinacea species were shown to be particularly effective in the treatment or prevention of the common cold.

Skin Conditions: Echinacea may be beneficial for some skin diseases, such as eczema and pruritus. In one such in vitro trial (conducted in a lab rather than on actual individuals), an extract of Echinacea purpurea was proven to lessen eczema symptoms. Researchers believed that the echinacea extract had anti-inflammatory properties that warranted further investigation.

In a short human experiment, Echinacea purpurea emulsions and shampoos were investigated for their possible advantages against pruritus (itchy skin).

Adult participants used echinacea extract-based emulsions or shampoos for four weeks. All kinds of topical echinacea significantly reduced pruritus and other characteristics, such as skin dryness.

Pain and Inflammation: Echinacea has been used for ages to relieve pain and inflammation. A thorough review published in 2021 found that echinacea may reduce proinflammatory cytokines (substances released by immune cells) while increasing anti-inflammatory cytokines.

This may be especially helpful during a cytokine storm, which occurs when proinflammatory cytokines are quickly released as a result of an illness. Echinacea may also help alleviate discomfort, which is frequently associated with inflammation.

Anxiety: Another reported advantage of echinacea is its anxiolytic (antianxiety) properties.

According to the findings, anxiety scores improved significantly in the echinacea group when compared to the placebo group, particularly in people who had high anxiety at the start of the trial.

Side Effects of Purple coneflower

Many people continue to use echinacea despite the fact that there are no established health advantages. It ranks among the top ten herbal supplements in the United States.

Echinacea is available in a variety of strengths and forms, and it is not regulated in the same way that medicines are. These considerations make it difficult to determine an appropriate dose. If you decide to take echinacea, follow the advice on the label and don’t take more than recommended.

Most people experience no negative effects from using echinacea, as long as they do not exceed the suggested dosage. However, as with any plant, echinacea is not for everyone. If you have a medical condition, take medications, or have allergies, see your doctor before consuming echinacea.

The most prevalent echinacea adverse effects are gastrointestinal in nature. Echinacea has the following common side effects:

  • Stomach ache
  • Diarrhea and constipation.
  • Skin rash and allergic reactions.
  • Nausea
  • In rare situations, echinacea use may cause a severe allergic reaction.

Do not use echinacea if you:

  • Are allergic to chrysanthemums, daisies, marigolds, or ragweed? Echinacea might induce a rash or a serious allergic reaction.
  • Are pregnant because the safety of this plant has not been established in pregnant women.
  • Have cervical or breast cancer, as echinacea may interact with some chemotherapy medicines for these illnesses.
  • Take immunosuppressants if you have an autoimmune disease or need to recover from an organ transplant. Echinacea may interact with these medications.
