If you’re passionate about native plants and love supporting local ecosystems, longspur lupine (Lupinus arbustus calcaratus) might just be the perfect addition to your garden. This perennial wildflower brings the classic beauty of lupines to your landscape while supporting the native plant communities of the American West.
What Makes Longspur Lupine Special?
Longspur lupine is a native perennial herb that belongs to the beloved lupine family. As a forb, it lacks woody stems but makes up for it with its herbaceous charm and staying power. This isn’t your typical garden center find – it’s a true native species that has been quietly thriving in western landscapes long before any of us started gardening.
You might also encounter this plant listed under its synonyms, including Lupinus arbustus var. calcaratus or Lupinus calcaratus, but they’re all referring to the same special plant.
Where Does It Call Home?
This lupine is a true westerner, naturally occurring across six states: California, Idaho, Nevada, Oregon, Utah, and Washington. Its native range spans diverse ecosystems throughout these regions, from coastal areas to inland valleys.
A Word About Rarity
Here’s something important to know: longspur lupine has a Global Conservation Status of S5T2T4, which indicates some level of conservation concern. This means if you’re lucky enough to find this plant available, make sure you’re getting it from a responsible, reputable source that propagates rather than wild-collects their plants. Never harvest from wild populations!

There are several compelling reasons to consider this native beauty:

Longspur lupine works beautifully in:
- Native plant gardens and natural landscapes
