Photo of American ginseng plant with ripe berries
American Ginseng
Panax quinquefolius
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.

White Snakeroot
Ageratina altissima (formerly Eupatorium rugosum)
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.

Solomon's Seal
Polygonatum biflorum
Solomon's seal grows statewide in moist, rich earth. The greenish-white flowers dangle like little bells beneath the leaves, under the gracefully arching stems.

Purple Milkweed
Asclepias purpurascens
The flowers of purple milkweed are pale purple to reddish purple to dark purple, with greenish or red tints. The scientific name means “becoming purple”: The flowers start off rather pale and become more intensely purplish as they mature.

Wood Spurge
Euphorbia commutata
Conspicuous in early spring, wood spurge is a dainty species with loose clusters of small, light green flowers. Look for it in woods, valleys, streamsides, and waste areas in Ozark landscapes.
Photo of pale Indian plantain flower clusters.
Pale Indian Plantain
Arnoglossum atriplicifolium (also Cacalia atriplicifolia)
The stout, smooth leaves of pale Indian plantain, with their glaucous-white coating beneath, look almost artificial. They are irregularly shaped, with pointed lobes. At the base of the plant, they can be 6 inches wide. They become gradually smaller up the stem.
Rope dodder stems
Dodders
Cuscuta spp.
Dodders are easy to identify, even though at first you might not recognize them as plants. These parasitic plants usually look like a hairlike mass of yellow or orange, leafless, wiry, vining stems wrapping around the stems of other plants.
Round-headed bush clover blooming on a prairie
Round-Headed Bush Clover (Roundhead Lespedeza)
Lespedeza capitata
Round-headed bush clover is a stiffly upright plant that has rounded flower clusters with cream-colored, pea-shaped flowers with purple markings on the banner petal. It grows statewide in open habitats.
Common Cocklebur
Xanthium strumarium
Common cocklebur occurs statewide in open, disturbed, lowland habitats. It is a common weed in crop fields. It has wide, rough, coarsely toothed leaves; stout, often purple-speckled stems; and characteristic burs with hooked spines.
Bur cucumber flowers and foliage
Bur Cucumber
Sicyos angulatus
Bur cucumber is a nonwoody, native, annual vine common in low, moist soils. It can spread across an area 20 feet wide, covering the ground and nearby shrubs. Note its lobed, gourd-family leaves, curly green tendrils, clusters of prickly, green, oval fruits, and 5-lobed, cream-colored flowers.

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri

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!
