Fringed Grass of Parnassus: A Rare Western Native Worth Knowing
Meet the fringed grass of Parnassus (Parnassia fimbriata var. intermedia), a charming native perennial that’s as intriguing as its name suggests. Despite its common name, this plant isn’t actually a grass at all – it’s a delicate flowering forb that calls the American West home.
Where You’ll Find This Native Beauty
This particular variety of fringed grass of Parnassus is native to three western states: Idaho, Nevada, and Oregon. As a truly native species to the lower 48 states, it has evolved alongside local wildlife and environmental conditions for thousands of years.
What Makes It Special
Parnassia fimbriata var. intermedia is classified as a perennial forb – essentially a non-woody flowering plant that comes back year after year. Unlike shrubs or trees, forbs like this one lack significant woody tissue and keep their growing points at or below ground level, helping them survive harsh winters.
You might also encounter this plant listed under its scientific synonyms: Parnassia cirrata Piper var. intermedia or Parnassia intermedia Rydb. These are simply different names botanists have used over the years as they’ve refined their understanding of plant relationships.
A Word of Caution: Rarity Matters
Here’s where things get interesting – and important. This variety carries a Global Conservation Status of S5T3, indicating it has some conservation concerns. If you’re lucky enough to encounter this plant or find seeds from a reputable source, it’s crucial to ensure any planting material is responsibly sourced. We want to appreciate these rare natives without putting wild populations at risk.
Growing Fringed Grass of Parnassus: The Challenge
Here’s where I need to be honest with you: specific growing information for Parnassia fimbriata var. intermedia is quite limited. This isn’t necessarily a bad thing – it just means this plant hasn’t made its way into mainstream horticulture yet. Many of our most treasured native plants started as difficult or unknown species before dedicated gardeners figured out their secrets.
Should You Try Growing It?
If you live within its native range and are passionate about growing rare natives, this could be an exciting challenge. However, given the limited cultivation information available, it’s probably best suited for:
- Experienced native plant gardeners
- Those interested in conservation gardening
- Gardeners willing to experiment and learn through trial
- Anyone working on habitat restoration projects in its native range
The Bottom Line
Parnassia fimbriata var. intermedia represents the fascinating world of lesser-known native plants. While we don’t have all the answers about growing it successfully, its status as a rare native makes it worthy of conservation attention. If you’re intrigued by this plant, consider connecting with native plant societies in Idaho, Nevada, or Oregon – they might have local knowledge and responsibly sourced materials.
Sometimes the most rewarding gardening adventures come from working with plants that haven’t been figured out yet. Who knows? You might be the gardener who unlocks the secrets to successfully cultivating this charming native forb.
