Scientific Name
Echinacea paradoxa
Family
Asteraceae (daisies, sunflowers)
Description

A perennial with an unbranched stem arising from basal leaves, with a single flowerhead. Disk flowers with spiny bracts. Ray flowers drooping, yellow, 1½–3½ inches long, notched at the tips. Basal leaves in a clump, strap-shaped, up to 8 inches long including stalks. Stem leaves shorter and lacking stalks. Fruits in a burrlike, dome-shaped head, blackening on drying.

Similar species: Our other coneflowers all have ray flowers that are pink or purplish pink. This is the only one with yellow ray flowers; this curious trait explains the species name, paradoxa. This species apparently sometimes hybridizes with other coneflowers. Hybrids usually have mottled or variegated ray corollas that can be a mix of pink and purple or may be orangish. Look for these in sites where yellow coneflower grows nearby the other species.

Size
Height: to 3 feet.
Where To Find
image of Yellow Coneflower Distribution Map
Scattered mostly in the western half of the Ozarks and Ozark Border regions. Cultivated statewide.
Grows in limestone and dolomite glades, balds, upland prairies, and savannas; also along roadsides. This species is nearly endemic to the Ozarks; that is, it occurs only in the Ozarks and no where else in the world. Like other members of its genus, it is targeted by root collectors who vandalize high-quality glades and prairies in public lands so they can sell the roots.
Missouri coneflowers are threatened by harvest for the medicinal herb market. Although coneflowers are easily cultivated, illegal and unethical root digging continues despite decades of studies failing to prove that echinacea supplements are medicinally effective.
As with other coneflowers, the flowers of this species are attractive to bees, butterflies, and other insects. Late in the season and continuing through winter, finches eat the seeds from the spiny-looking, spent flowerheads. Rodents eat seeds that fall to the ground.

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!
