Field Guide

Yellow wood sorrel is both a garden weed and a wild edible. It has a pleasant sour taste, which is why some people call it sourgrass and add it to salads.

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.

Water lilies are among the most beautiful of all water plants. They have large, round leaves 8–16 inches across, each with a single V-shaped notch.

American lotus is an aquatic plant with circular leaves that are held above water. The large yellow flowers have an interesting showerhead-like disk at the center.

Arrowheads are aquatic plants with erect, usually arrow-shaped leaves and distinctive three-petaled flowers. They are often called duck potatoes because ducks, geese, and swans relish the tuberlike rootstocks.

A tall, smooth, branching plant with red stems and juicy, dark purple berries, pokeweed is both toxic and a traditional edible potherb called poke salat. It is common statewide.

This native lily looks a lot like the Asian “tiger lily” that is commonly cultivated in gardens. Michigan lily, however, has leaves mostly in whorls and lacks the round “bulblets” that tiger lily forms in its leaf axils.

The flowers of dayflower are truly blue, and they have only two conspicuous petals. A fast-growing, sprawling, but shallow-rooted weed, this introduced species commonly annoys gardeners.

White crownbeard is a tall native perennial wildflower with clusters of white flowerheads. It's called “wingstem” for the narrow green wings running along the stem. It’s called “frostweed” because it forms "frost flowers": strange and beautiful formations at the stem bases after a sudden hard frost.

Called carpenter’s weed for its remarkably square stems, cup plant is also notable for its large, opposite leaves that fuse around the stem to form a leafy cup that holds rainwater.
