Murray’s Rockcress: A Charming Native Groundcover for Your Garden
Looking for a low-maintenance native plant that brings delicate beauty to challenging garden spots? Meet Murray’s rockcress (Arabis murrayi), a delightful perennial that’s perfectly at home in the American Northwest. This unassuming little charmer might just be the missing piece in your native plant puzzle.
What Makes Murray’s Rockcress Special?
Murray’s rockcress is a native perennial forb that stays true to its common name – it absolutely loves rocky, well-draining spots where other plants might struggle. As a herbaceous plant (meaning it doesn’t develop woody stems), it forms attractive low-growing rosettes that hug the ground and produce clusters of small, four-petaled white flowers in spring.
This native beauty calls Montana and Washington home, making it a perfect choice for gardeners in the Pacific Northwest and northern Rocky Mountain regions who want to support local ecosystems while adding subtle elegance to their landscapes.

- Pollinator magnet: Those small white flowers are perfect landing pads for native bees and other beneficial insects
- Low-maintenance lifestyle: Once established, it’s remarkably drought-tolerant and requires minimal fussing
- Problem-solver plant: Thrives in those tricky spots where drainage is excellent but conditions are tough
