Scientific Name
Echinacea simulata

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!

An invasive native of Eurasia that is spreading in Missouri, musk thistle is a plant you should know. Learn how to tell the difference between our native thistles and these bad guys.

Scientific Name
Cirsium vulgare
Description
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.

Scientific Name
Cirsium altissimum
Description
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.

Scientific Name
Cirsium arvense
Description
Canada thistle is a native to Eurasia and arrived on our continent probably before the Revolutionary War — most likely mixed in agricultural seed. A bad weed of crop fields and rangeland farther north, it causes problems in Missouri, too.

Scientific Name
Galium aparine
Description
The tiny white flowers of this native plant are not very memorable, but the curious, sticky-feeling whorls of narrow leaves and lightweight, 4-sided stems make cleavers unique. And then there’s the tiny, round, “Velcro” covered balls of the seeds, which “stick tight” to your socks!

Scientific Name
Opuntia humifusa (formerly O. compressa)
Description
Cacti make us think of the desert southwest, but there is at least one species native to Missouri. This prickly pear grows in glades, sand prairies, rocky open hillsides, and other dry, sun-soaked areas.

Hydrilla is probably the worst submersed aquatic weed in America. It harms aquatic communities in small ponds, lakes, and rivers. It hurts our economy by hindering fishing and other recreational uses in large reservoirs. Learn about it and prevent its spread.

Coontail, a common submerged aquatic plant, got its name from the crowded upper leaves, which make the stem tip appear bushy like the tail of a raccoon.

A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
