Field Guide

In summer, you’re almost guaranteed to see big colonies of crown vetch along Missouri's highways. This weedy nonnative plant stabilizes the dirt after road construction but degrades our natural ecosystems.

Small blue, lavender, or white flowers shaped like cornucopias dance along the tall stems of this Carolina larkspur, which grows in prairies and grasslands.

A spiny annual with bright yellow flowers and dandelion-like leaves, buffalo bur is an introduced member of the nightshade family.

Full grown, water hemlock looks something like a gigantic Queen Anne's lace, but this common, widespread member of the carrot family is the most toxic plant in North America. All parts are deadly. A piece of root the size of a walnut can kill a cow-sized animal.

Native to much of eastern North America, eastern red columbine's range almost matches the breeding territory of the ruby-throated hummingbird, its number-one pollinator. Its bloom time matches the hummingbird's northward migration, too.

White wild indigo is the tallest species of false indigo in Missouri. It has a robust, striking presence, with white flowers and a shrubby look. Look for it statewide, in prairies and glades and along roadsides, streams, and valleys.

Sesbania, a type of legume, may become a troublesome species in wetland communities that are managed for waterfowl.
