May Prairie State Natural Area

July 20

Helianthus eggertii

This is another joint hike with the new Middle Tennessee Wild Ones group and TNPS. The “Oak Barrens” of Coffee County provide examples of TN rare plants that are disjunct from the Gulf Coastal Plain and the prairies of the Midwest. The primary goal of this outing is to see Snowy Orchid (Platanthera nivea) in flower. This is the only location known in Tennessee for this Coastal Plain species. Usually flowering with it is the equally rare Coastal False Asphodel (Tofieldia racemosa, now Triantha racemosa). We should also see Mock Bishop’s Weed (Ptilimnium costatum), Enyngo (Eryngium integrifolium), Coppery St. Johnswort (Hypericum denticulatum), three Silphiums, including Shaggy Rosinweed (Silphium mohrii) which is endemic to TN, AL, and GA, Swamp Rose (Rosa palustris), and Virginia Goldenrod (Solidago austrina).

Difficulty: Easy to moderate walking in low vegetation.
