Description

The large, showy, rose-purple flower heads of purple coneflower make it a standout in open woodlands as well as in the home garden. The genus name, Echinacea, means “hedgehog” and refers to the flower’s spiny center cone.

Purple coneflower is a native perennial wildflower with large, daisy-like flowers with spreading, slightly drooping magenta “petals” (ray flowers). The stems are unbranched or with few to several ascending branches, with stiff hairs.

The basal leaves have long stems and grow to 6 inches long; they are coarsely toothed, oblong, and rounded at the base. The upper leaves are smaller, lance-shaped, and may or may not have stems.

The flowerheads are usually solitary, terminal (only at the stem tips), and quite large. The disk (center) is orange and spiny. The ray flowers range from pink to purple (rarely white) and are spreading to only somewhat drooping.

Blooms May through October.

The fruits are achenes (structurally similar to sunflower "seeds"), wedge-shaped, angled, slightly flattened, tan to nearly white.

Similar species: Five species of coneflowers (Echinacea) are recorded growing wild in Missouri.

  • The two most similar, that you are most likely to see, are pale purple coneflower (E. pallida) and glade coneflower (E. simulata), which both have pinkish-purple ray flowers (in both of these, however, the petal-like rays are more slender and more drooping than those of purple coneflower).
  • Yellow coneflower (E. paradoxa), with its yellow rays, is easy to identify by its different color.
  • Narrow-leaved coneflower (E. angustifolia) is rare in Missouri and has only been recorded sporadically over the decades. It is a Great Plains species. In 2014, it was finally located in Missouri, in a native loess hill prairie in the northwest corner of the state. Its pinkish-purple flowers resemble glade and pale purple coneflowers, but the rays are only about half as long, and are more spreading, less drooping. The pollen is yellow. It is ranked as critically imperiled in Missouri.
Size

Height: to about 3 feet.

Where To Find

Scattered nearly throughout the state, though mostly absent from the Bootheel and northwestern Missouri.

Though this species is scattered in the wild, it is widely grown in cultivation.

Occurs in moist to dry upland woodlands, savannas, upland prairies, ledges and tops of bluffs, banks of streams, and rarely fens and sinkholes; also in pastures, old fields, railroads, and roadsides.

This species prefers moister soils than other species of coneflower.

This species is the one most likely to be encountered as an ornamental in cultivation, and a number of cultivars and hybrids are available commercially.

Native Missouri wildflower. Popular native perennial plant for landscaping. Attracts pollinators.

In gardens, purple coneflowers are showy, long-blooming, hardy, and good for cut flowers. It is often used in roadside beautification projects. This species, along with various hybrids and cultivars, is commonly available at garden centers.

Native Americans used the roots of coneflowers to make medicines, and modern herbalists continue to use this extract, called Echinacea after the genus name, for treating the common cold and other ailments.

Many species of coneflowers have suffered in the wild due to indiscriminate, often illegal root-digging for the international herbal medicine market.

This species is a good nectar source for butterflies and bees.

In winter, goldfinches relish its seeds.

Its network of root fibers help to bind soils, protecting against erosion.

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri
A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
