Rare plant alert!

Region: Conservation status by state

Status: S5T3T4: 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. ⚘ Subspecies or varieties is apparently secure: Uncommon but not rare, and usually widespread. Possibly cause for longterm concern. Typically more than 100 occurrences in the region 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. ⚘

King Bladderpod var. Cobrensis: A Rare Native Gem Worth Protecting

If you’re passionate about native plant gardening and have a soft spot for botanical rarities, King bladderpod variety cobrensis (Lesquerella kingii kingii var. cobrensis) might just capture your heart. This lesser-known native forb represents one of nature’s more specialized treasures, quietly thriving in select corners of the American West.

Meet the King Bladderpod

King bladderpod var. cobrensis is a native herbaceous plant that belongs to the mustard family. As a forb, it’s neither a woody shrub nor a grass, but rather a soft-stemmed flowering plant that can live as either a biennial or perennial, depending on growing conditions. Don’t let its humble classification fool you – this plant carries the dignified King title in its common name for good reason.

Where Does It Call Home?

This particular variety of King bladderpod has carved out its niche across three western states: Idaho, Nevada, and Oregon. It’s perfectly adapted to the unique growing conditions found in these regions, making it a true child of the American West.

A Word About Rarity

Important consideration: King bladderpod var. cobrensis has a conservation status of S5T3T4, which indicates some level of conservation concern. If you’re interested in growing this plant, it’s crucial to source it responsibly from reputable native plant nurseries that propagate their own stock rather than collecting from wild populations.

Why Consider This Native Plant?

Here are compelling reasons why King bladderpod var. cobrensis deserves a spot in your native plant garden:

  • Native heritage: Supporting indigenous flora helps maintain regional ecological balance
  • Low maintenance: Once established, native plants typically require less water and care than non-natives
  • Habitat support: Native plants provide food and shelter resources that local wildlife evolved to depend on
  • Conservation contribution: Growing rare natives helps preserve genetic diversity

Garden Role and Design Ideas

As a forb, King bladderpod var. cobrensis works beautifully in:

  • Native plant gardens
  • Rock gardens and xeriscapes
  • Naturalized areas
  • Conservation landscapes
  • Educational gardens focused on regional flora

Growing Conditions and Care

While specific cultural requirements for this exact variety are not widely documented, King bladderpods generally prefer:

  • Well-draining soils
  • Full to partial sun exposure
  • Minimal irrigation once established
  • Rocky or sandy soil conditions

Since this plant is native to Idaho, Nevada, and Oregon, it’s naturally adapted to the climate conditions found in these regions. Gardeners in similar climates will have the best success.

Responsible Growing Practices

Given its conservation status, here’s how to grow King bladderpod var. cobrensis responsibly:

  • Source ethically: Purchase only from nurseries that propagate their own plants
  • Never collect from the wild: Wild populations need protection
  • Share responsibly: If you successfully grow it, consider sharing seeds or propagated plants with other native plant enthusiasts
  • Document your success: Keep notes about what works in your garden to help other growers

The Bottom Line

King bladderpod var. cobrensis represents both an opportunity and a responsibility for native plant gardeners. While it may not be the showiest plant in your garden, growing it connects you to the specialized ecosystems of the American West while contributing to conservation efforts. Just remember: with rare natives comes the responsibility to source and grow them ethically.

For gardeners outside its native range, consider exploring native alternatives that provide similar ecological benefits in your specific region. Your local native plant society can point you toward appropriate substitutes that will thrive in your climate while supporting local wildlife.
