Missouri has 24 species of New World asters in genus Symphyotrichum. Most have purple or white ray flowers and yellow disk flowers that turn reddish over time. Most bloom in late summer and fall.

Cobaea beardtongue, or purple beardtongue, is probably Missouri’s showiest species of penstemon. Native to Missouri's southern Ozarks, it is grown statewide for its beauty, and because pollinators like it. It may be purple or white.

Missouri boasts nine native species of blazing stars, or gayfeathers, in genus Liatris. These showy, upright, unbranching spikes of magenta-pink wildflowers bloom in sunny habitats.

Cylindrical blazing star is one of several Missouri native species of blazing stars, or gayfeathers. It is widely scattered in the Ozarks and eastern Missouri. Identify it by its bracts, which are pressed against the base of the flowerhead, accentuating its cylindrical look.

Scaly blazing star is one of several Missouri native species of blazing stars, or gayfeathers. It is scattered nearly statewide. Identify it by its long-pointed flowerhead bracts that spread or curl sharply away.

Five species of ironweeds live in Missouri. Starting in the middle of summer, they bear showy clusters of magenta or purple flowerheads at the branching tops of upright stalks.

Curlytop ironweed is one of Missouri’s five species of ironweeds. It’s easy to identify because of its tapering, curling, threadlike involucral bracts. Also, it is usually a smooth, hairless plant.

Red clover, or purple clover, is the familiar large, pinkish-purple clover that grows in lawns, pastures, and roadsides statewide. A Eurasian native, it was introduced to North America by the middle 1600s.

Round-headed bush clover is a stiffly upright plant that has rounded flower clusters with cream-colored, pea-shaped flowers with purple markings on the banner petal. It grows statewide in open habitats.
