Silvery Lupine: A Rare Native Gem from the Colorado Plateau
If you’re drawn to native plants with a touch of mystery, Lupinus argenteus moabensis might just capture your gardening imagination. This particular variety of silvery lupine is a true regional specialty, calling only Colorado and Utah home. But before you start planning where to plant it, there are some important things every responsible native gardener should know.
What Makes This Lupine Special?
The silvery lupine (Lupinus argenteus moabensis) is a perennial forb that belongs to the pea family. Unlike woody shrubs or trees, this herbaceous plant lacks significant woody tissue above ground, instead putting its energy into beautiful flowering displays year after year. You might also see it listed under its synonym Lupinus argenteus Pursh var. moabensis, but they’re referring to the same plant.
Where You’ll Find It Growing Wild
This native beauty has a pretty exclusive address – you’ll only find it naturally occurring in Colorado and Utah. It’s perfectly adapted to the unique conditions of this region, making it a true Colorado Plateau endemic.

- No observations
A Word of Caution: Rarity Matters
Here’s where things get important for ethical gardeners. This silvery lupine variety has a Global Conservation Status of S5T2T4, which indicates it has some level of rarity concern. While this doesn’t mean you absolutely can’t grow it, it does mean you should be extra thoughtful about how you source it.
If you’re interested in growing this plant:
- Only purchase from reputable native plant nurseries
- Never collect seeds or plants from wild populations
- Ask your nursery about the source of their plants
- Consider supporting habitat conservation in its native range
Growing Challenges and Considerations
Here’s the honest truth: specific cultivation information for Lupinus argenteus moabensis is quite limited. This isn’t unusual for rare native varieties that haven’t been widely cultivated. What we do know is that as a Colorado Plateau native, it’s likely adapted to:
- Well-draining soils
- Full sun conditions
- Low to moderate water requirements once established
- The temperature extremes typical of high desert regions
Is This the Right Plant for Your Garden?
This silvery lupine might be perfect for you if you’re creating a Colorado Plateau-themed garden, live within its native range, and are committed to responsible native gardening practices. However, given the limited cultivation information and rarity concerns, it might not be the best choice for beginning native gardeners or those looking for a low-maintenance ground cover.
Alternative Options
If you love the idea of native lupines but want something with more available growing information, consider researching other Lupinus species native to your specific area. Many regions have their own native lupines that are better studied and more readily available from ethical sources.
The Bottom Line
Lupinus argenteus moabensis represents the fascinating world of regional native plant varieties – beautiful, specialized, and deserving of our respect and protection. While it can potentially be grown in gardens, it requires a thoughtful approach that prioritizes conservation and responsible sourcing. Sometimes the best way to appreciate a rare native plant is to support its preservation in the wild while choosing more common native alternatives for our home landscapes.
