Field Guide

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.

Large stands of wind-pollinated giant ragweed commonly form in disturbed areas, causing late-summer misery in the form of hay fever for many Missourians.

Tickseed sunflower has flattened black seeds that attach themselves to clothing and pets via two needlelike awns. In flower, it grows in massive displays in moist bottomlands.

Wood nettle, or stinging nettle, often forms dense stands in bottomland forests, streamsides, and other places. There, canoeists, anglers, and others try to avoid touching its stinging hairs!

Horseweed looks something like a goldenrod, except that the tiny composite flowers are not yellow. Instead, they are cream-colored and rather drab. In Missouri, this plant is especially associated with disturbed habitats and is a troublesome crop weed.

You may not recognize elephant’s foot as a member of the daisy or sunflower family because it lacks petal-like ray florets. Also, it has unusual, doubly compound flower clusters. And how did it get its name, anyway?
