Pinto Beardtongue: A Desert Gem Worth Growing Responsibly
Meet the pinto beardtongue (Penstemon bicolor), a stunning native wildflower that’s perfectly at home in the American Southwest’s harsh desert landscapes. This perennial beauty might just be the drought-tolerant showstopper your xeriscape garden has been waiting for – but there’s an important catch we need to discuss first.
What Makes Pinto Beardtongue Special?
The pinto beardtongue is a native forb – that’s garden-speak for a soft-stemmed perennial herb that dies back to the ground each winter and returns with fresh growth in spring. What sets this particular penstemon apart is right there in its name: bicolor refers to its gorgeous two-toned tubular flowers that bloom in shades of pink to purple, creating a striking contrast that catches the eye from across the garden.
Where Does It Call Home?
This desert native has carved out its niche across three southwestern states: Arizona, California, and Nevada. You’ll find it thriving in the Mojave and Sonoran desert regions, where it has adapted beautifully to intense heat, minimal rainfall, and rocky, well-draining soils.
A Word of Caution: Rarity Status
Here’s where we need to pump the brakes a bit. Pinto beardtongue carries a Global Conservation Status of S3, meaning it’s considered vulnerable. With only 21 to 100 known occurrences and an estimated 3,000 to 10,000 individuals remaining in the wild, this isn’t a plant to take lightly. If you’re considering adding it to your garden, please – and we can’t stress this enough – only source plants or seeds from reputable native plant nurseries that propagate rather than wild-collect their stock.
Why Your Garden (and Local Wildlife) Will Love It
Despite its vulnerable status in the wild, pinto beardtongue can be a fantastic garden addition when responsibly sourced. Here’s why:
- Those tubular flowers are hummingbird magnets – expect regular visits from these tiny aerial acrobats
- Native bees and butterflies also find the blooms irresistible
- Once established, it’s incredibly drought-tolerant
- Perfect for rock gardens, xeriscaping, and native plant landscapes
- Low maintenance – it actually prefers being left alone
Growing Conditions: Keep It Simple
Pinto beardtongue thrives in USDA hardiness zones 8-10, making it suitable for warmer climates. Here’s what this desert native needs to flourish:
- Sun: Full sun exposure – the more, the better
- Soil: Well-draining sandy or rocky soil (heavy clay is a no-go)
- Water: Minimal once established – think desert plant, not garden perennial
- Fertilizer: None needed – rich soils can actually harm desert natives
Planting and Care Tips
Fall planting gives your pinto beardtongue the best start, allowing roots to establish before the heat of summer arrives. Plant in a location with excellent drainage – if water pools after rain, find a different spot or create a raised mound.
The biggest mistake gardeners make with desert natives? Too much kindness in the form of water and fertilizer. Once established (usually after the first year), water deeply but infrequently, and skip the fertilizer entirely. Your pinto beardtongue will reward your benign neglect with healthy growth and abundant blooms.
The Bottom Line
Pinto beardtongue deserves a place in southwestern gardens – it’s beautiful, supports native wildlife, and epitomizes the plant it and forget it gardening philosophy we all secretly love. Just remember to source responsibly and give this vulnerable native the respect it deserves. When we grow rare natives in our gardens, we’re not just creating beauty – we’re becoming conservation partners, helping ensure these special plants have a future beyond their wild habitats.
