Field Guide

White snakeroot looks very similar to thoroughworts, but it has triangular leaf blades that are more broadly angled or rounded at the base. White snakeroot is common statewide. It’s a toxic plant if eaten, so it’s good to be able to identify it.

Solomon's seal grows statewide in moist, rich earth. The greenish-white flowers dangle like little bells beneath the leaves, under the gracefully arching stems.

“It’s an odd plant,” this rattlesnake master, “with its leaves like yucca, a head like a thistle, and second cousin to the carrot.” That’s how the great prairie writer John Madson summed it up!

Mead's milkweed, an endangered wildflower, once flourished in the tallgrass prairies of the midwestern United States, including most of Missouri.

Whorled milkweed has rounded clusters of small white flowers. The leaves are soft, threadlike, and grow in whorls from the stem. It occurs in upland prairies and fields.

Prairie milkweed’s full, rounded clusters of small, delicately purple-tinged flowers set it apart from other prairie milkweeds.

Hogwort is fuzzy, densely covered with whitish hairs. A common but often overlooked plant in pastures, prairies, ditches, and roadsides, it’s usually less than 18 inches tall.

Milkweeds are a group of plants that used to have their very own family. Now part of the dogbane family, they’re still a pretty distinctive group.
