Field Guide

Prairie cordgrass is a native perennial sod-forming grass with flowering stalks up to 7 feet tall. A grassland species, it grows in dense stands in low, damp soils. It’s often called ripgut because of the tiny sharp saw teeth on the leaf edges.

Prairie dropseed is a native perennial bunch grass that forms dense clumps of fine, light green, arching leaves. The seed heads are airy, open, branching clusters bearing small, ovate florets on their own individual branchlets.

Showy lady’s slipper is a beautiful and rare wildflower. This orchid can be more than 3 feet tall, with showy flowers with a pink-suffused, inflated lower lip. In Missouri, it's restricted to the southern portion of the Ozarks.

Showy orchis is a perennial wildflower of rich, moist, shady woods, slopes, ravines, and stream valleys, often found with other spring wildflowers. It’s about 6 inches tall when it produces its beautiful pink and white flowers.

Of Missouri’s three species lady’s slipper orchids, small white lady’s slipper is the only one with white “slippers,” which are shiny and look almost like glazed porcelain. Today, it’s known from only one location in the Ozarks.

Crested coral root is an orchid that lacks chlorophyll, so none of it is green. It obtains nutrients from fungi and decaying organic matter. Compared to our other coral roots, it is taller and has larger flowers. It grows in Ozark habitats.

Spring coral root blooms in April and May. Except for a few small sheathing bracts along the stem, it has no leaves. The purplish or brownish flowers are in a raceme at the tip of the stem. Each flower’s lower lip is white with purple markings.

Spring ladies’ tresses is Missouri’s tallest species of spiranthes orchid. It’s one of four species that have their flower clusters in a single, easy-to-discern spiral, but another key feature is that it blooms as early as June and July.

The tuberous grass pink is one of two species of grass pinks in Missouri. It lives in Ozark fens and is rare in the state. Like other orchids in genus Calopogon, its flowers seem upside down.
