Field Guide

Japanese stiltgrass is an invasive annual grass with thin, pale green, lance-shaped leaves that are 3 inches long. It has spread to nearly every eastern U.S. state. It forms dense patches, displacing and outcompeting native species for nutrients and light.

Wild onion is edible and is also favored by native-plant gardeners, who enjoy its showy umbels of pink flowers and tolerance of dry, rocky sites. This Ozark species blooms in summer and fall.

In spring, wild hyacinth bears an elongated cluster of pale blue flowers with prominent anthers that sway on stalks up to 2 feet tall.

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.

There are 23 species of goldenrods in Missouri. They can be hard to identify to species, but as a group, the goldenrods are common and nearly unmistakable.

Deptford pink has straight, strong, narrow stems that bear small clusters of pink flowers with white dots. Common statewide in sunny, open locations such as pastures and roadsides.

It has grasslike leaves, but it’s not a grass. In fact, it’s in the same family as the common garden iris! Four species of blue-eyed grass grow in Missouri, and this one, often found on prairies, glades, and pastures, is the most common.

Missouri’s cattails are all tall wetland plants with narrow, upright leaves emerging from a thick base, and a central stalk bearing a brown, sausage-shaped flower spike.

Native to Europe and Asia, orange day lily was widely planted by early settlers and has become widely naturalized in North America. The seeds don't mature in Missouri, so all the plants here are spread by root divisions.
