Napkinring: A Rare California Native Worth Protecting

Meet the napkinring (Eriogonum intrafractum), a perennial wildflower that’s as elusive as its quirky common name suggests. This little-known California native belongs to the buckwheat family and represents one of nature’s more secretive treasures. While you might be curious about growing this unique plant, there are some important conservation considerations every gardener should know about.

A True California Original

Napkinring is authentically Californian through and through. This perennial forb herb is native exclusively to the Golden State, making it a true endemic species. Unlike many plants that spread across multiple states or regions, napkinring has chosen to call only California home, which makes it both special and vulnerable.

Why This Plant Needs Our Protection

Here’s where things get serious: napkinring carries a Global Conservation Status of S2, which means it’s imperiled. In plain terms, this plant is extremely rare, with typically only 6 to 20 known occurrences and possibly fewer than 1,000 to 3,000 individual plants remaining in the wild. This rarity status puts napkinring in a precarious position where every plant matters.

As a responsible gardener, this rarity status should be a red flag. While the desire to grow unique native plants is admirable, napkinring’s imperiled status means we need to think twice about cultivation.

What Makes Napkinring Special

Napkinring grows as a perennial forb herb, meaning it’s a non-woody plant that comes back year after year. Like other members of the buckwheat family, it likely produces small clusters of flowers, though specific details about its appearance and growing habits remain largely undocumented due to its rarity.

Should You Plant Napkinring?

The short answer is: proceed with extreme caution, if at all. Given napkinring’s imperiled conservation status, here are the key considerations:

  • Wild collection is absolutely off-limits – Never harvest seeds or plants from wild populations
  • Commercial availability is virtually nonexistent – You’re unlikely to find this plant at nurseries
  • Cultivation information is lacking – Growing requirements, care instructions, and propagation methods are largely unknown
  • Conservation efforts take priority – Wild populations need protection more than gardens need this plant

Better Alternatives for Your Garden

Instead of seeking out napkinring, consider these more common and readily available California native buckwheats that can provide similar ecological benefits:

  • California Buckwheat (Eriogonum fasciculatum) – Widely available and excellent for pollinators
  • Saint Catherine’s Lace (Eriogonum giganteum) – Stunning white flower clusters
  • Coastal Buckwheat (Eriogonum latifolium) – Great for coastal gardens
  • Sulfur Flower (Eriogonum umbellatum) – Beautiful yellow blooms

Supporting Conservation

If you’re passionate about rare California natives like napkinring, consider supporting conservation organizations working to protect these imperiled species. You can also participate in citizen science projects that help track rare plant populations or volunteer with habitat restoration efforts.

The best way to honor napkinring and other rare natives is to create habitat for common native species that support the same ecosystems. By planting readily available California natives in your garden, you’re creating stepping stones and refugia that benefit entire plant communities.

The Bottom Line

While napkinring’s rarity makes it fascinating from a botanical perspective, its imperiled status means it’s best admired from afar and left in its natural habitat. Focus your gardening efforts on more common native alternatives that can provide similar benefits without conservation concerns. Remember, the most responsible way to appreciate rare plants is to protect them where they naturally occur.
