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!

Indian hemp is a shrubby, upright perennial with opposite branches and milky sap. This native plant can be a troublesome weed in crop fields and gardens, but Native Americans used its tough, fibrous stems for rope-making.

Often found on gravelly Ozark streamsides, shining blue star lifts its clusters of showy, light-blue flowers in late spring. A top choice for native wildflower gardening, it is interesting spring, summer, and fall.

Most common in the Ozarks, round-leaved groundsel is one of seven Packera species in our state. Its showy, bright yellow, daisylike flowers form flat-topped clusters that arise from sparsely leaved stems.

Golden aster can cover entire valleys with its bright yellow flowers. It blooms June through October and is scattered mostly south of the Missouri River.

In Europe, St. John’s-wort was long used as a medicinal herb and to ward off evil magic. Today, researchers are finding it can treat depression. Yet it poisons livestock and in some places is an invasive weed.

A tall, smooth, branching plant with red stems and juicy, dark purple berries, pokeweed is both toxic and a traditional edible potherb called poke salat. It is common statewide.
