Field Guide

Every Missourian should know big bluestem. It is the most famous of our native prairie grasses. The seed head of this tall grass branches into three parts, resembling a turkey’s foot.

With its white, petal-like ray florets and pale disc florets, upland white goldenrod is truly the oddball of the goldenrods: it looks like a white-flowered aster. Indeed, it used to be considered an aster.

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.

Switchgrass is a native perennial, warm-season, clump-forming mid or tall grass. In midsummer, delicate-looking, open, multiply-branching flowering clusters rise above the foliage.

Virginia wild rye can be identified by its bristly seed heads, which are held erect and whose bristle-like awns stay straight. This is a common native perennial tuft-forming, cool-season midgrass usually reaching about 2–4 feet in height.

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.
