Field Guide

Rough blazing star is fairly common and scattered nearly statewide. To distinguish between Missouri’s nine species in the genus Liatris, start by noting details of the flower structure. It’s not hard when you know what to look for.

In summer and fall, the pretty blue flowers of chicory decorate roadsides and other disturbed areas. This weedy member of the aster family was introduced from Europe long ago. Its roots have been used as a coffee substitute.

Spotted knapweed is an invasive plant that outcompetes native communities, takes over pastureland, and even beats back invasive sericea lespedeza! It has arrived in our state. Let’s prevent its spread.

Mist flower, or wild ageratum, is a vigorous native perennial bearing fluffy-looking, bluish-purple flowerheads. It looks quite a bit like the annual ageratum that is sold as a bedding plant in garden centers.

Called “crane’s bill” for its sharply pointed seed capsules, wild geranium is a gardening favorite, and there are cultivated varieties of this woodland wildflower bred for unique petal and leaf colors.

A low-growing wildflower that can colonize large areas along roadsides, showy evening primrose bears pink or white flowers that seem too large for the vegetation that supports them.

Woollen breeches bears clusters of light blue, bell-shaped flowers. The lower leaves of this hairy plant are shaped something like maple leaves and often have grayish or light green marks that look like water stains.

Although the funnel-shaped, 5-lobed flowers look something like the petunias you find at garden centers, our wild petunia is not related to them. This ruellia often has crinkled hairs in 2 narrow, lengthwise bands on opposite sides of the stalk.

What could be cooler than finding a green dragon? This leafy green plant with a long, noodly spadix is closely related to Jack-in-the-pulpit. It occurs in the same habitats but is less common and easily overlooked.

Hispid buttercup is a densely hairy plant with showy yellow flowers. It is found mostly in the southern half of Missouri, usually in moist locations.
