Rydberg’s Goldenbush: A Rare Native Shrub Worth Knowing
If you’re passionate about growing truly unique native plants, Rydberg’s goldenbush (Ericameria obovata) might just catch your attention. This lesser-known perennial shrub represents one of nature’s more specialized creations—a plant that’s carved out its own particular niche in the American West.
What Makes Rydberg’s Goldenbush Special?
Rydberg’s goldenbush is a native perennial shrub that belongs to the sunflower family. Like other shrubs, it’s a multi-stemmed woody plant that typically stays under 13-16 feet in height, though it usually grows much smaller. This hardy little plant has earned its place in the native plant world through sheer persistence and adaptation to specific conditions.
Where Does It Call Home?
This goldenbush is a true Utah native, found exclusively within the state’s borders. Its limited geographic range makes it a special find for native plant enthusiasts who want to support local biodiversity. The plant has quite a taxonomic history, having been known by several scientific names including Haplopappus rydbergii and Macronema obovatum—a testament to botanists’ ongoing efforts to properly classify our native flora.
Why Consider Growing Rydberg’s Goldenbush?
Here’s where things get interesting—and important. This plant carries a conservation status of S3S4, which indicates it may face some challenges in its natural habitat. For gardeners, this presents both an opportunity and a responsibility:
