Zion Goldenbush: A Rare Desert Treasure Worth Protecting
Meet the Zion goldenbush (Isocoma humilis), a plant that’s become something of a botanical mystery. This low-growing perennial shrub once called the landscapes of Utah home, but today it stands as a sobering reminder of how quickly our native flora can slip away from us.
What Makes Zion Goldenbush Special?
The Zion goldenbush is a compact, unassuming shrub that typically stays under 1.5 feet tall, though it can occasionally reach up to 3 feet at maturity. As a perennial member of the sunflower family, it was perfectly adapted to Utah’s challenging desert conditions. You might also see it referenced by its scientific synonym, Haplopappus leverichii, in older botanical literature.
A Plant on the Brink
Here’s where the story takes a concerning turn. The Zion goldenbush currently holds a Global Conservation Status of SH, which means Possibly Extirpated. In plain English? This little shrub is known only from historical records, and botanists aren’t even sure if it still exists in the wild. While there’s still hope for rediscovery, no confirmed populations have been documented in recent years.
This rare status is limited to Utah, where the species was historically native to the lower 48 states.
Should You Grow Zion Goldenbush?
The short answer is: probably not, and here’s why. Given its precarious conservation status, the Zion goldenbush isn’t something you’ll find at your local nursery, nor should it be. If this species still exists somewhere in Utah’s wild landscapes, those remaining plants are far too precious to disturb.
If you’re absolutely determined to grow this species, it should only be done with:
- Seeds or plants from verified, responsibly managed conservation programs
- Coordination with botanical institutions or conservation organizations
- A commitment to contributing to species recovery efforts
Better Alternatives for Your Native Garden
Instead of seeking out this rare treasure, consider these fantastic native alternatives that can give you similar desert charm without conservation concerns:
- Desert Broom (Baccharis sarothroides) – Another low-maintenance desert shrub
- Rubber Rabbitbrush (Ericameria nauseosa) – Brilliant yellow flowers and excellent pollinator support
- Four O’Clock (Mirabilis multiflora) – Native Utah groundcover with stunning evening blooms
What We Can Learn
The story of Zion goldenbush serves as an important reminder about the fragility of our native ecosystems. While we can’t turn back the clock on this species’ decline, we can make more mindful choices about the native plants we do choose to cultivate.
By focusing our gardening efforts on native species that are stable and readily available through ethical sources, we can create beautiful landscapes while supporting local ecosystems—without putting additional pressure on our rarest botanical treasures.
Sometimes the best way to honor a rare plant is simply to remember it existed and to do better by the native species we still have the privilege to grow.
