Montezuma County Beardtongue: A Vanishing Wildflower Worth Preserving

Meet Montezuma County beardtongue (Penstemon parviflorus), a native wildflower that’s become something of a botanical mystery. This perennial forb represents one of nature’s most elusive treasures, and if you’re thinking about adding it to your garden, there are some important things you need to know first.

A Plant on the Edge of History

Here’s where things get serious: Montezuma County beardtongue has a Global Conservation Status of SH, which means it’s Possibly Extirpated. In plain English, this plant is known only from historical records, and scientists aren’t even sure it still exists in the wild. There’s still hope for rediscovery, but this little beardtongue has earned its place among North America’s most endangered native plants.

Where It Once Called Home

This rare beardtongue was historically found in Colorado and New Mexico, making it a true native of the American Southwest. As a plant native to the lower 48 states, it once contributed to the unique ecological tapestry of its high desert homeland.

What We Know (And What We Don’t)

As a perennial forb, Montezuma County beardtongue lacks significant woody tissue and would have persisted year after year through underground parts. Like other members of the Penstemon family, it likely produced tubular flowers that attracted pollinators, but specific details about its appearance, size, and growing habits have largely been lost to time.

Unfortunately, much of what we’d love to tell you about this plant remains unknown:

  • Specific growing conditions and habitat preferences
  • Flower color and plant appearance
  • Wildlife and pollinator relationships
  • Cultivation requirements and care tips

Should You Try to Grow It?

This is where we need to pump the brakes a bit. Given its possibly extirpated status, Montezuma County beardtongue should only be grown if you can obtain responsibly sourced material – and frankly, that’s extremely unlikely to happen. If any seeds or plants ever become available through legitimate conservation programs, they would be precious beyond measure.

Instead of searching for this elusive species, consider supporting its conservation by:

  • Planting other native Penstemon species from Colorado and New Mexico
  • Supporting botanical gardens and conservation organizations working to rediscover lost species
  • Creating habitat for native pollinators that might help this species if it’s ever found again

The Bigger Picture

Montezuma County beardtongue serves as a sobering reminder of what we can lose when native habitats disappear. While we can’t give you a care guide for this particular species, we can encourage you to plant other native beardtongues that are still thriving and available through reputable native plant sources.

Every garden that celebrates native plants becomes a small sanctuary, and who knows? Maybe somewhere in the high country of Colorado or New Mexico, a tiny population of Montezuma County beardtongue is still hanging on, waiting to be rediscovered by the next generation of botanical explorers.
