Carson Range Rockcress: A Rare Alpine Gem Worth Protecting
If you’re passionate about rare native plants and love the challenge of alpine gardening, Carson Range rockcress might just capture your heart. This delicate perennial, known scientifically as Arabis tiehmii, is a true treasure of the American West – though one that requires our careful stewardship.
What Makes Carson Range Rockcress Special?
Carson Range rockcress is a low-growing perennial that forms charming mats or cushions adorned with small, four-petaled white flowers in spring. Don’t expect a showy display – this plant’s beauty lies in its subtle elegance and the story it tells of survival in harsh mountain conditions.
This remarkable little plant calls the high elevations of California and Nevada home, where it has adapted to thrive in rocky, well-draining soils and cool mountain air. It’s a true native of the lower 48 states, making it an authentic piece of American botanical heritage.
A Plant That Needs Our Help
Important Conservation Note: Carson Range rockcress has a Global Conservation Status of S2, meaning it’s considered imperiled due to extreme rarity. With typically only 6 to 20 occurrences and few remaining individuals in the wild, this species is especially vulnerable to extinction.
If you’re considering adding this rare beauty to your garden, please only source it from reputable nurseries that propagate plants responsibly rather than collecting from wild populations. By growing Carson Range rockcress in cultivation, you can help preserve this species for future generations.

This isn’t a plant for every gardener, but it’s perfect if you:
- Love alpine and rock garden plants
- Want to support rare native species conservation

Growing Carson Range Rockcress Successfully
Climate Requirements: This mountain native thrives in USDA hardiness zones 4-7, where it can experience the cool temperatures it craves.
Light and Soil Needs: Provide full sun to partial shade and, most importantly, exceptionally well-draining soil. Think rocky, gravelly conditions that mimic its natural mountain habitat. Poor drainage is likely the quickest way to lose this plant.
Watering Wisdom: Once established, Carson Range rockcress prefers minimal water. Overwatering is more dangerous than drought for this mountain specialist.
