Silvery Nailwort: A Sparkling Native Ground Cover for Challenging Spots
If you’re searching for a tough, low-maintenance ground cover that adds a touch of silvery sparkle to your garden, meet silvery nailwort (Paronychia argyrocoma). This charming native perennial might not be the showiest plant in your garden, but it’s certainly one of the most resilient—and it brings a subtle beauty that grows on you over time.
What Makes Silvery Nailwort Special?
Silvery nailwort is a native perennial forb that forms dense, low-growing mats or cushions. What really catches the eye are its distinctive silvery-white, papery bracts that shimmer in the sunlight, giving the plant an almost ethereal quality. Don’t expect towering height from this humble ground-hugger—it stays close to the earth, making it perfect for tucking into rock crevices or carpeting difficult slopes.
As a member of the pink family (Caryophyllaceae), this little plant produces small, inconspicuous flowers, but it’s really all about those eye-catching silvery bracts that give it both its common name and its garden appeal.
Where Does Silvery Nailwort Call Home?
This eastern North American native has quite an impressive range, growing naturally across twelve states and the District of Columbia: Georgia, Kentucky, Maine, Maryland, Massachusetts, New Hampshire, North Carolina, Tennessee, Vermont, Virginia, and West Virginia. You’ll typically find it thriving in mountainous regions, particularly throughout the Appalachian Mountains, where it has adapted to challenging rocky and sandy conditions.
