Starveling Milkvetch: A Rare Wyoming Native Worth Protecting
If you’ve stumbled across the name starveling milkvetch in your native plant research, you’ve discovered one of Wyoming’s botanical treasures. This perennial legume, scientifically known as Astragalus jejunus var. articulatus, is about as rare as native plants get – and that’s exactly why it deserves our attention and respect.
What Makes This Plant Special?
Starveling milkvetch is a native perennial that calls the lower 48 states home, though you’ll only find it naturally growing in Wyoming. As a member of the legume family, it likely shares the nitrogen-fixing superpowers that make many of its relatives valuable to ecosystems. The common name starveling hints at this plant’s ability to thrive in challenging conditions where other plants might struggle.
Where You’ll Find It (Or Won’t)
Here’s where things get interesting – and a bit sobering. Starveling milkvetch has an extremely limited range, found only in Wyoming. This narrow distribution is part of what makes it so special, but also so vulnerable.
The Rarity Factor: Why This Matters
With a conservation status of S3T1, starveling milkvetch falls into the rare and vulnerable category. This means that while it exists, its populations are limited and potentially at risk. For gardeners and native plant enthusiasts, this raises an important question: should you try to grow it?
Should You Plant Starveling Milkvetch?
Here’s our honest take: probably not, unless you’re participating in a legitimate conservation effort. Here’s why:
- Its rarity means wild collection could harm natural populations
- Very little is known about its specific growing requirements
- Seeds or plants are extremely difficult (if not impossible) to source responsibly
- It’s adapted to very specific Wyoming conditions that might be hard to replicate elsewhere
What We Don’t Know (And Why That Matters)
The truth is, there’s a lot we don’t know about growing starveling milkvetch. Information about its preferred growing conditions, propagation methods, garden performance, and even its exact appearance is scarce. This knowledge gap is common with rare native plants that haven’t been brought into cultivation.
Better Alternatives for Your Native Garden
If you’re inspired by the idea of growing native milkvetches, consider these more readily available alternatives that can provide similar ecological benefits:
- Purple prairie clover (Dalea purpurea)
- White prairie clover (Dalea candida)
- Other regionally appropriate Astragalus species
- Native vetches and other legumes suited to your area
How You Can Help
Instead of trying to grow starveling milkvetch in your garden, consider supporting its conservation in other ways:
- Support organizations working to protect Wyoming’s native plant habitats
- Choose other rare natives that have been responsibly propagated for garden use
- Participate in citizen science projects that help document rare plant populations
- Focus your garden on locally native species that support regional ecosystems
The Bigger Picture
Starveling milkvetch reminds us that not every native plant needs to become a garden staple – and that’s okay. Some plants serve their most important role by simply existing in their natural habitats, maintaining the intricate web of relationships that keep ecosystems healthy. By respecting these boundaries, we become better stewards of the plant diversity that makes our natural world so remarkable.
Sometimes the best way to appreciate a rare native plant is to leave it be, while working to protect the places where it naturally thrives.
