Ironweeds are tough, grayish-green, branching plants known for their fluffy-looking clusters of reddish-purple florets. They are a familiar sight on roadsides and pastures. Identify western ironweed by the bracts at the base of the flowerheads.

White anemone is a showy native wildflower with interesting, deeply toothed leaves. Often occurring in colonies, it spreads easily (even aggressively) from rhizomes and is sometimes cultivated in wildflower gardens.

White snakeroot looks very similar to thoroughworts, but it has triangular leaf blades that are more broadly angled or rounded at the base. White snakeroot is common statewide. It’s a toxic plant if eaten, so it’s good to be able to identify it.

American, or common boneset has small, white flowerheads in flat-topped clusters at the top of the plant. The leaves are hairy, narrowly triangular, and in opposite pairs fused around the stem.

A stout perennial that can grow to 6 feet tall, tall thoroughwort is a member of the sunflower family that has dull white flowers and distinctive leaves that are opposite, slender, very short-stalked, and with three quite noticeable veins.

Mist flower, or wild ageratum, is a vigorous native perennial bearing fluffy-looking, bluish-purple flowerheads. It looks quite a bit like the annual ageratum that is sold as a bedding plant in garden centers.

Hispid buttercup is a densely hairy plant with showy yellow flowers. It is found mostly in the southern half of Missouri, usually in moist locations.

Hibiscus in Missouri? You bet! Hairy rose mallow is a native perennial whose 6-inch-wide blossoms look a lot like those of its tropical relatives. The stalks can get woody and can grow to 8 feet tall.
