Clingman’s Hedgenettle: A Rare Native Gem Worth Protecting
If you’re a native plant enthusiast with a passion for conservation, Clingman’s hedgenettle (Stachys clingmanii) might just capture your heart—and your sense of environmental responsibility. This delicate annual wildflower represents something truly special in the native plant world: a rare treasure that needs our help to survive.
What Makes Clingman’s Hedgenettle Special?
Clingman’s hedgenettle is a charming member of the mint family that embodies the understated beauty of our native flora. As an annual forb, this herbaceous plant completes its entire life cycle in just one growing season, making each plant precious and fleeting. Its small white to pale purple flowers arranged in terminal spikes create a delicate, almost ethereal appearance that whispers rather than shouts in the garden.
A Plant on the Edge: Understanding Its Rarity
Here’s where things get serious, fellow gardeners. Clingman’s hedgenettle carries a Global Conservation Status of S2, meaning it’s imperiled throughout its range. With typically only 6 to 20 known occurrences and an estimated 1,000 to 3,000 remaining individuals, this plant is walking a tightrope toward extinction. Every single plant matters.
Important: If you’re considering adding this species to your garden, please only use responsibly sourced material from reputable native plant nurseries that practice ethical propagation. Never collect from wild populations.
Where Does It Call Home?
This rare native spans across 13 states in the eastern United States, including Alabama, Arkansas, District of Columbia, Illinois, Indiana, Kentucky, Maryland, North Carolina, South Carolina, Tennessee, Vermont, Virginia, and West Virginia. Its distribution tells the story of a plant that once thrived across diverse eastern ecosystems but now clings to existence in scattered locations.

Growing Conditions and Care

By growing this plant, you’re not just adding beauty to your garden—you’re providing critical habitat for insects that might be just as rare as the plant itself.
