Plateau Catchfly: A Rare Utah Native Worth Protecting

Meet the plateau catchfly (Silene petersonii var. petersonii), one of Utah’s most exclusive botanical residents. This perennial wildflower is so particular about where it calls home that you’ll only find it in a handful of spots across the state. If you’re thinking about adding this beauty to your garden, well, let’s have a chat about why that might not be the best idea – and what you can do instead to support this remarkable plant.

What Makes Plateau Catchfly Special

The plateau catchfly is a herbaceous perennial forb, which is just a fancy way of saying it’s a non-woody flowering plant that comes back year after year. As part of the pink family (Caryophyllaceae), it shares some family traits with more familiar garden plants like carnations and chickweed, though it’s far more finicky about its living situation.

Where to Find This Rare Beauty

Here’s where things get exclusive: plateau catchfly is found only in Utah, making it what botanists call an endemic species. This plant has carved out a very specific niche in high-elevation plateau environments, where the growing conditions are just right for its survival.

Why You Shouldn’t Plant It (But Should Care About It)

Before you start scouring nurseries for plateau catchfly seeds, here’s the important part: this plant has a Global Conservation Status of S2S3T2, which indicates it’s quite rare and potentially vulnerable. This means a few crucial things for gardeners:

  • Wild populations are small and fragile
  • The plant has very specific habitat requirements that are nearly impossible to replicate in typical gardens
  • Collecting seeds or plants from the wild could harm already vulnerable populations
  • It’s likely not available through commercial sources anyway

Supporting Conservation Instead

Rather than trying to grow plateau catchfly in your garden, here are better ways to support this rare species:

  • Support local conservation organizations working to protect Utah’s native habitats
  • Choose other native Utah plants that are more common and garden-appropriate
  • Learn about and visit (respectfully) the natural areas where rare plants like this grow
  • Spread awareness about the importance of protecting endemic species

Garden-Friendly Alternatives

If you’re drawn to the idea of growing native catchflies, consider these more garden-suitable alternatives that won’t put rare species at risk:

  • Other Silene species that are more common and adaptable
  • Native Utah wildflowers with similar growing requirements
  • Perennial forbs that support local pollinators and wildlife

The Bigger Picture

Plants like plateau catchfly remind us that not every beautiful native species is meant for our gardens – and that’s perfectly okay. Sometimes the best way to appreciate and protect rare plants is to leave them in their specialized habitats where they’ve evolved to thrive. By choosing more common native alternatives for our gardens and supporting conservation efforts for rare species, we can have the best of both worlds: beautiful native gardens and protected wild populations of our most precious botanical treasures.

The next time you’re in Utah’s high country, keep an eye out for this special little plant. Just remember: look but don’t touch, and definitely don’t dig. Some plants are worth more as wild treasures than as garden specimens.
