Susanville Beardtongue: A Rare Gem for Your Native Garden

Meet the Susanville beardtongue (Penstemon sudans), a charming little wildflower that’s as special as it is beautiful. This delicate perennial herb might not be the showiest plant in the garden, but what it lacks in size, it more than makes up for in character and ecological value.

What Makes Susanville Beardtongue Special?

The Susanville beardtongue is a true California and Nevada native, found naturally in just a small corner of the world – northeastern California and western Nevada. This little herb belongs to the snapdragon family and produces lovely tubular flowers that range from white to pale pink or soft lavender. The blooms appear in late spring to early summer, creating delicate spikes that dance in the breeze.

As a perennial forb (that’s botanist-speak for a non-woody flowering plant), this beardtongue comes back year after year, slowly forming small clumps that add subtle beauty to any native plant collection.

Where Does It Call Home?

This regional treasure grows naturally in California and Nevada, with most populations centered around the Susanville area – hence the name! It’s perfectly adapted to the high desert conditions of this region, making it a fantastic choice for gardeners in similar climates.

A Word of Caution: Handle with Care

Here’s something important to know: Susanville beardtongue has a Global Conservation Status of S3, meaning it’s considered vulnerable in the wild. With typically only 21 to 100 known occurrences and between 3,000 to 10,000 individuals remaining, this little plant needs our help.

If you’re thinking of adding this beauty to your garden (and we hope you are!), please make sure you source your plants or seeds from reputable native plant nurseries that propagate their own stock. Never collect from wild populations – let’s help this special plant thrive rather than struggle.

Sun and Soil

Give your Susanville beardtongue:

Planting and Care Tips

  • Best planting time: Spring, after the last frost
  • Watering: Water regularly the first season to establish roots, then cut back dramatically
  • Fertilizing: Skip it! This plant actually prefers poor soils
  • Maintenance: Deadhead spent flowers to encourage more blooms, but leave some for seed production
  • Winter care: Cut back dead foliage in late fall or early spring
