This charming native perennial brings delicate purple blooms and drought tolerance to gardens across the Great Basin region, though it comes with an important conservation consideration we’ll discuss.

What is Tunnel Springs Beardtongue?

Tunnel Springs beardtongue (Penstemon concinnus) is a native perennial herb that belongs to the snapdragon family. As a forb, it’s a non-woody flowering plant that dies back to the ground each winter and returns fresh each spring. Don’t let its delicate appearance fool you – this little powerhouse is perfectly adapted to survive in some pretty tough conditions!

Where Does It Call Home?

This beautiful beardtongue is native to the lower 48 states, specifically calling Nevada and Utah home. You’ll find it naturally growing in the Great Basin region, where it has adapted to the area’s unique climate and soil conditions over thousands of years.

Why You Might Want to Grow It (And One Important Consideration)

Here’s where things get interesting – and important. Tunnel Springs beardtongue has a Global Conservation Status of S3, meaning it’s considered vulnerable. With typically only 21 to 100 occurrences or between 3,000 and 10,000 individuals in the wild, this plant needs our help.

If you decide to grow this rare beauty, please only purchase from reputable native plant nurseries that use responsibly sourced, locally collected seed. Never collect plants from the wild!

That said, here’s why it’s worth growing responsibly:

  • Supports native pollinators, including native bees and hummingbirds
  • Extremely drought tolerant once established
  • Perfect for water-wise landscaping
  • Adds authentic regional character to native plant gardens
  • Low maintenance once established

Tunnel Springs beardtongue produces clusters of small, tubular flowers in lovely shades of purple to violet. The blooms have that classic beardtongue shape that pollinators absolutely love. The plant features narrow, lance-shaped leaves that form an attractive base for the flowering stems.

Growing Conditions

  • Soil: Well-draining soil (this is crucial!)
  • Water: Drought tolerant once established
  • Maintenance: Very low once established

Planting and Care Tips

Getting your Tunnel Springs beardtongue off to a good start is pretty straightforward:

  • Plant in spring after the last frost
  • Ensure excellent drainage – soggy soil is this plant’s biggest enemy

  • Deadhead spent flowers to encourage more blooms
