Wild and cultivated ginseng produce an annual crop in the United States and Canada valued in excess of $25 million, but overzealous collection is causing serious concern about the survival of American ginseng in the forest ecosystem.

In summer, you’re almost guaranteed to see big colonies of crown vetch along Missouri's highways. This weedy nonnative plant stabilizes the dirt after road construction but degrades our natural ecosystems.

Missouri has one introduced and four native wood sorrels. Violet wood sorrel is the only one that has magenta or lavender flowers.

Mullein immigrated to America along with Europeans, and with them it has spread across the continent. Its fuzzy, green-gray rosettes of leaves and tall spikes of yellow flowers make it easy to identify.

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.

Small blue, lavender, or white flowers shaped like cornucopias dance along the tall stems of this Carolina larkspur, which grows in prairies and grasslands.

These two species of sweet clover are present all over America. Although they have been planted for forage, as bee plants, and as nitrogen-fixers, white and yellow sweet clover are now classified as invasive for their weediness and the problems they pose for natural habitats.

Wild strawberry is one of the parents of the cultivated strawberry and is one of our prized native wild edibles. It’s also a valuable food for innumerable animals, and it’s attractive in native wildflower gardens.

Common cinquefoil, or five-finger, is named for its leaves, which are divided into five fingerlike leaflets. One of seven cinquefoils in Missouri, it blooms from April to June and is scattered nearly statewide.
