Cusick’s Lupine: A Rare Oregon Native Worth Knowing About
If you’re passionate about native plants and conservation, you’ve probably never heard of Cusick’s lupine (Lupinus cusickii abortivus) – and there’s a very good reason for that. This incredibly rare perennial forb represents one of Oregon’s most elusive botanical treasures, existing in such small numbers that most gardeners will never encounter it in the wild, let alone in cultivation.
What Makes This Plant So Special?
Cusick’s lupine belongs to the beloved lupine family, those stunning wildflowers that paint western landscapes in brilliant blues and purples each spring. As a perennial forb, it’s an herbaceous plant that dies back to the ground each winter and returns from its roots the following growing season. Like other lupines, it’s part of the legume family, which means it has the fascinating ability to fix nitrogen in the soil through a partnership with beneficial bacteria.
This particular subspecies has quite the botanical resume, having been known by several scientific names over the years, including Lupinus abortivus Greene and Lupinus aridus Douglas var. abortivus.
Where in the World Can You Find It?
Here’s where things get really interesting (and a bit concerning). Cusick’s lupine is native to the United States and calls Oregon home. However, its distribution is so limited that it has earned a Global Conservation Status of S1TH, which essentially means it’s critically imperiled and possibly extinct in the wild.

Should You Try to Grow Cusick’s Lupine?
Here’s the honest truth: you almost certainly can’t grow this plant, and you probably shouldn’t try to find it. With its extremely rare status, Cusick’s lupine falls into that category of plants that are best left to professional botanists, conservation organizations, and specialized native plant preserves. Even if you could somehow obtain seeds or plants, doing so might contribute to further pressure on wild populations.
The rarity of this subspecies means that:
- It’s not available through normal nursery channels
- Wild collection would be harmful to remaining populations
- Its specific growing requirements are not well documented
- It may already be extinct in the wild
Better Alternatives for Your Garden
While you can’t grow Cusick’s lupine, you can still support native lupines and create beautiful wildflower gardens! Oregon is home to several other native lupine species that are more readily available and better suited for home gardens. Consider these alternatives:
- Broadleaf lupine (Lupinus latifolius)
- Silvery lupine (Lupinus argenteus)
- Large-leaved lupine (Lupinus polyphyllus)
These species offer similar ecological benefits, including nitrogen fixation, pollinator support, and the classic lupine aesthetic that makes western wildflower meadows so spectacular.
What This Plant Teaches Us
Cusick’s lupine serves as a powerful reminder of why native plant conservation matters. Every rare subspecies like this one represents thousands of years of evolution and adaptation to very specific environmental conditions. When we lose these plants, we lose genetic diversity and resilience within plant communities.
As native plant gardeners, we can honor plants like Cusick’s lupine by:
- Growing other native lupines that support similar ecological functions
- Supporting conservation organizations working to protect rare plants
- Never collecting plants from the wild
- Choosing responsibly sourced native plants for our gardens
While we may never see Cusick’s lupine gracing our garden beds, knowing about its existence reminds us that every native plant – common or rare – plays an important role in the web of life. By cultivating other native species, we’re doing our part to support biodiversity and create resilient ecosystems, one garden at a time.
