If you’re looking for a native grass that brings subtle beauty and ecological value to your landscape, bearded skeletongrass (Gymnopogon ambiguus) might be just what you need. This charming perennial grass may not win any flashy flower contests, but its delicate, wispy appearance and native credentials make it a wonderful choice for naturalistic gardens and woodland edges.

What Makes Bearded Skeletongrass Special?

Bearded skeletongrass is a native perennial grass that forms loose, airy tufts with fine-textured foliage. True to its name, this grass has a somewhat skeletal appearance – not in a spooky way, but rather with an elegant, minimalist structure that adds texture without overwhelming other plants in your garden.

This native grass calls a large swath of the United States home, naturally occurring across 24 states including Alabama, Arkansas, Delaware, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, New Jersey, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and West Virginia, plus the District of Columbia.

A Word of Caution: Rarity Matters

Before you rush out to find this grass, there’s something important to know: bearded skeletongrass has a rarity status of S3 (vulnerable) and is Highlands Listed in New Jersey. This means that while it’s a fantastic native choice, you’ll want to source it responsibly from reputable native plant nurseries rather than collecting it from the wild.
