Field Guide

One of Missouri’s most distinctive ferns, walking fern walks. Its long, triangular leaves take root at the elongated tips, forming new plantlets.

Purple cliff brake is a fern that grows from crevices in limestone and dolomite rocks, or in rocky soils near them. Its leathery, blue-gray leaflets, which are oval to lance-shaped, make the fronds seem not very fernlike.

Smooth cliff brake is almost always seen growing out of an exposed limestone or dolomite bluff or rock. Its fronds, with blue-gray, lance-shaped, ovate, or oblong leaflets, are not very fernlike.

Lamb’s quarters won’t win any beauty contests for its flowers, but it merits an award for being both a common garden weed as well as a nutritious leafy green valued around the world.

Not the showiest of wildflowers, American bugleweed will catch your eye with its interesting geometry. The narrow, toothed leaves are opposite on the stalks and occur at right angles to the pair below.

Common cocklebur occurs statewide in open, disturbed, lowland habitats. It is a common weed in crop fields. It has wide, rough, coarsely toothed leaves; stout, often purple-speckled stems; and characteristic burs with hooked spines.

Violets, as a group, are fairly easy to identify, with their colorful five-petaled “faces” so welcome in springtime. Missouri has 17 species, and some are confusingly similar. This page introduces them as a group.

Ragworts, or groundsels, have several common names, and separating the different species can be a little tricky. But members of genus Packera, with their bright yellow daisy-like flowers, are distinctive as a group. Seven species have been recorded in Missouri.

Prairie ragwort is one of seven Packera species in our state. It grows in sunny, open habitats. Look for its clusters of bright yellow, daisylike flowers in May and June.
