Rare plant alert!

Region: Conservation status by state

Status: S4S5T3: Status is uncertain but is somewhere between the following rankings: 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. ⚘ Apparently Secure: Uncommon but not rare, and usually widespread. Possibly cause for longterm concern. Typically more than 100 occurrences in the state or more than 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. ⚘

Haresfoot Locoweed: A Rare Native Wildflower Worth Knowing

If you’re passionate about native plants and love discovering lesser-known species, you might find yourself intrigued by haresfoot locoweed (Oxytropis lagopus var. conjugans). This perennial wildflower is one of those quiet native gems that doesn’t get much attention in mainstream gardening circles, but it has its own unique place in North America’s natural heritage.

What Is Haresfoot Locoweed?

Haresfoot locoweed is a native perennial forb—essentially a non-woody flowering plant that comes back year after year. As a member of the legume family, it shares characteristics with other locoweeds, though this particular variety has its own distinct qualities. The plant’s common name likely refers to the fuzzy, rabbit-foot-like appearance of its flower clusters or seed pods.

Where Does It Grow Naturally?

This native wildflower has a limited natural range, currently documented in Montana and Alberta. Its restricted distribution makes it a special find for plant enthusiasts in these regions. The plant is native to both Canada and the lower 48 United States, though its presence appears to be quite localized.

Should You Grow Haresfoot Locoweed?

Here’s where things get a bit complicated. While haresfoot locoweed is undoubtedly a fascinating native plant, there are several important considerations before adding it to your garden:

  • Rarity concerns: This variety has a Global Conservation Status of S4S5T3, indicating it may be of conservation concern
  • Limited availability: Due to its restricted range and potential rarity, finding seeds or plants may be challenging
  • Specialized needs: Like many rare natives, it likely has specific growing requirements that may be difficult to replicate in typical garden settings

If You’re Determined to Try It

Should you decide to attempt growing haresfoot locoweed, responsible sourcing is absolutely critical. Never collect seeds or plants from wild populations, as this could harm already limited natural stands. Instead:

  • Work only with reputable native plant nurseries that can verify the source of their material
  • Consider participating in conservation seed collection programs if available in your area
  • Connect with local botanical gardens or native plant societies for guidance

Growing Conditions and Care

Unfortunately, specific growing information for this variety is quite limited in available literature. Based on its natural habitat in Montana and Alberta, it likely prefers:

  • Well-draining soils
  • Full sun to partial shade
  • Cooler climate conditions
  • Minimal fertilization (like most native legumes)

As a perennial forb, it would die back to the ground each winter and emerge again in spring.

Alternative Native Options

Given the challenges associated with growing haresfoot locoweed, you might consider other native legumes that are more readily available and better understood. Look for locally native species of:

  • Wild lupine (Lupinus species)
  • Prairie clover (Dalea species)
  • Milk vetch (Astragalus species)
  • Other Oxytropis species that are more common in your area

The Bottom Line

Haresfoot locoweed represents the kind of specialized native plant that’s more suited to conservation efforts and botanical collections than typical home gardens. While it’s certainly a plant worth knowing about and appreciating, the average gardener might find more success and make a bigger conservation impact by focusing on other native species that are better documented and more readily available.

If you’re in Montana or Alberta and passionate about rare natives, consider connecting with local conservation organizations—you might find opportunities to help with research or habitat restoration that would benefit this and other uncommon species far more than individual garden plantings.
