Region: Conservation status by state

Status: S5T2T3: Status is uncertain but is somewhere between the following rankings: Subspecies or variety is imperiled: Extremely rare due to factor(s) making it especially vulnerable to extinction. Typically 6 to 20 occurrences or few remaining individuals (1,000 to 3,000) ⚘ Subspecies or variety is vulnerable: Either very rare and local throughout its range, found only in a restricted range (even if abundant at some locations), or factors are making it vulnerable to extinction. Typically 21 to 100 occurrences or between 3,000 and 10,000 individuals. ⚘ Secure: At very low or no risk of extinction in the jurisdiction due to a very extensive range, abundant populations or occurrences, with little to no concern from declines or threats. ⚘

Nodding Locoweed: A Rare Rocky Mountain Native Worth Protecting

If you’re passionate about native plants and conservation gardening, you might have stumbled across the intriguingly named nodding locoweed (Oxytropis deflexa var. pulcherrima). This lesser-known native perennial represents one of nature’s more specialized Rocky Mountain residents, and there are some important things every gardener should know before considering it for their landscape.

What Makes Nodding Locoweed Special

Nodding locoweed is a perennial forb—essentially a soft-stemmed flowering plant that dies back each winter but returns from its roots year after year. As a native species to the lower 48 states, it has evolved specifically to thrive in the unique conditions of the American West, making it a true regional treasure.

Where You’ll Find This Rocky Mountain Native

This particular variety of nodding locoweed calls three western states home: Colorado, New Mexico, and Utah. It’s perfectly adapted to the challenging growing conditions of these high-elevation regions, where temperature swings are dramatic and growing seasons can be short.

The Rarity Factor: Why This Matters

Here’s where things get important for conservation-minded gardeners. Nodding locoweed carries a Global Conservation Status of S5T2T3, which indicates this variety may be uncommon to rare in its natural habitat. This means that while the broader species might be stable, this particular variety faces some conservation challenges.

What this means for gardeners: If you’re considering adding nodding locoweed to your garden, it’s crucial to source plants or seeds only from reputable native plant nurseries that practice responsible collection methods. Never collect from wild populations, as this could further stress already limited natural communities.

Is Nodding Locoweed Right for Your Garden?

The honest answer is that we have limited information about the specific cultivation requirements for this variety. What we do know is that as a Rocky Mountain native, it likely prefers:

  • Well-draining soils (mountain plants typically hate wet feet)
  • Full sun to partial shade conditions
  • Cool to moderate temperatures
  • Minimal water once established

The Conservation Gardener’s Approach

Given the rarity status of this plant, there are a few approaches you might consider:

For the Conservation Enthusiast: If you live within its native range and are committed to native plant conservation, sourcing this plant from a specialized native nursery could contribute to preservation efforts. Just make sure any nursery you work with practices ethical propagation.

For the Practical Gardener: Consider exploring other native Oxytropis species or similar native forbs that might be more readily available and better studied for garden cultivation.

Supporting Native Plant Conservation

Whether or not you choose to grow nodding locoweed in your garden, you can support its conservation by:

  • Supporting organizations that protect native plant habitats
  • Choosing other native plants for your landscape
  • Learning about and protecting natural areas in your region
  • Participating in citizen science projects that monitor rare plant populations

The Bottom Line

Nodding locoweed represents the fascinating diversity of native plants that have evolved in specific regional conditions. While we may not have all the cultivation details figured out for home gardens, its story reminds us of the importance of protecting native plant diversity. If you’re drawn to this rare beauty, proceed thoughtfully and always prioritize conservation over collection.

Sometimes the best way to appreciate a rare native plant is to support its protection in wild spaces while choosing more common natives for our home landscapes. Either way, you’re contributing to the important work of native plant conservation.
