One of Missouri’s five types of echinaceas, glade coneflower is distinguished by its yellow pollen, drooping pink or purple ray flowers, and narrow, tapering leaves. Look for it in the eastern Ozarks, and at native plant nurseries!

Rough blazing star is fairly common and scattered nearly statewide. To distinguish between Missouri’s nine species in the genus Liatris, start by noting details of the flower structure. It’s not hard when you know what to look for.

Spotted knapweed is an invasive plant that outcompetes native communities, takes over pastureland, and even beats back invasive sericea lespedeza! It has arrived in our state. Let’s prevent its spread.

Called “crane’s bill” for its sharply pointed seed capsules, wild geranium is a gardening favorite, and there are cultivated varieties of this woodland wildflower bred for unique petal and leaf colors.

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.

White heath aster is one of Missouri's most widespread and weedy native asters. It grows in uplands, bottomlands, and nearly all habitats in between. It has a shrubby, wide-branching habit, and the stem leaves are thin and needlelike.

One of Missouri's five types of echinacea, pale purple coneflower is distinguished by its white pollen, drooping pink or purple ray flowers, and narrow, tapering leaves. It occurs nearly statewide, except for the Bootheel lowlands.

Large-flowered gaura is a tall plant whose white flowers turn pinkish as they age. Four petals point upward, then bend back, and 8 stamens droop downward. The flowers look something like small butterflies.

The antique belief that this plant might repel fleas gives the fleabanes their name. There are more than 170 fleabanes in the genus Erigeron in North America. This one is scattered to common nearly throughout Missouri. Native Americans used this species medicinally for a variety of ailments.
