This delightful perennial wildflower brings both beauty and ecological benefits to landscapes across the American West, making it a fantastic choice for gardeners who want to support local wildlife while enjoying gorgeous blooms.
What is Mountain Goldenbanner?
Mountain goldenbanner (Thermopsis montana) is a native perennial forb that calls the western United States home. As a forb, it’s a non-woody plant that dies back to the ground each winter but returns reliably year after year. This cheerful wildflower produces striking yellow, pea-like flowers arranged in tall, showy spikes that can’t help but catch your eye.
Being native to the lower 48 states gives mountain goldenbanner serious credibility in the native gardening world. It’s perfectly adapted to western growing conditions and has co-evolved with local wildlife over thousands of years.
Where Does It Grow Naturally?
Mountain goldenbanner has quite an impressive range across the western states. You’ll find it growing wild in Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. This wide distribution tells us it’s a pretty adaptable plant that can handle various conditions across different elevations and climates.

Planting and Establishment Tips
Getting mountain goldenbanner started in your garden is straightforward:

Special Considerations
Mountain goldenbanner has a facultative wetland status in western regions, meaning it can handle both wet and dry conditions. This flexibility makes it particularly valuable for areas that experience seasonal moisture changes or for gardeners dealing with variable rainfall.
Keep in mind that this plant may spread via underground rhizomes, so give it space to naturalize if you want a more informal look, or be prepared to manage its spread in more formal settings.
The Bottom Line
Mountain goldenbanner is a winner for western native plant enthusiasts. It’s beautiful, supports local ecosystems, requires minimal fussing once established, and brings that coveted wild look to cultivated gardens.
