Field Guide

The yellow violet is Missouri's only all-yellow violet. This native wildflower is less common than violet violets. Look for it in low woods, rich slopes, and wooded floodplains.

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.

Mayapple is a common spring wildflower that makes its biggest impression with its leaves, which resemble umbrellas arising from a single stalk. It often grows in colonies.

Bull thistle is a weedy introduction from Europe, found statewide. To tell it from our other thistles, note its stems with spiny-margined wings, and its leaves with the upper surface strongly roughened with stiff, spiny bristles.

Tall thistle is a native thistle that can grow to be 10 feet tall! To identify it, notice its leaves, which are unlobed (though they may be wavy or have only shallow, broad lobes), are felty-hairy beneath, and have prickles only along the edges.

Wild strawberry is one of the parents of the cultivated strawberry and is one of our prized native wild edibles. It’s also a valuable food for innumerable animals, and it’s attractive in native wildflower gardens.

Three species of yucca grow wild in Missouri. Spanish bayonet was introduced from the Southwest and has escaped from cultivation, but our two soapweeds are native.

Missouri has two species of sweet cicely, which can be hard to tell apart. Both have umbels of small white flowers, fernlike leaves, and sweetly aromatic, carrotlike roots.
