If you’re passionate about native plants and have a special fondness for rare beauties, Ward’s false goldenweed (Oonopsis wardii) might just capture your heart. This charming perennial herb is one of Wyoming’s botanical treasures, offering delicate yellow blooms and a fascinating story of survival in some of the West’s most challenging landscapes.
What Makes Ward’s False Goldenweed Special?
Ward’s false goldenweed is a true Wyoming native, found nowhere else in the world except within the state’s boundaries. This perennial forb produces clusters of small, bright yellow composite flowers that bloom in late summer, creating a cheerful display when many other plants are winding down for the season. The plant maintains a compact, low-growing form with narrow leaves that help it conserve moisture in its arid mountain home.
Where Does It Grow Naturally?
This special plant calls Wyoming home, where it thrives in the high-elevation landscapes of the Greater Yellowstone ecosystem and surrounding areas. It’s perfectly adapted to the state’s challenging climate, including harsh winters, intense summer sun, and limited rainfall.
A Word About Conservation
Important: Ward’s false goldenweed has a Global Conservation Status of S3, meaning it’s considered vulnerable. With typically only 21 to 100 occurrences and between 3,000 and 10,000 individuals in the wild, this plant needs our protection. If you’re interested in growing it, please only obtain plants or seeds from reputable native plant nurseries that source material responsibly and legally.

However, it might not be the best choice if you’re looking for a low-maintenance plant for beginners or if you live outside its natural climate range, as it can be challenging to establish and maintain.
Growing Conditions and Care
