Cody’s Rockcress: A Rare Arctic Beauty for Specialized Gardens
If you’re passionate about rare native plants and have a thing for Arctic beauties, Cody’s rockcress might just capture your heart. This delicate perennial is one of those special plants that makes you feel like you’re harboring a little piece of the northern wilderness right in your backyard.
What Makes Cody’s Rockcress Special
Arabis codyi, commonly known as Cody’s rockcress, is a charming perennial forb that belongs to the mustard family. Don’t let the forb label intimidate you – it simply means this plant lacks woody stems and dies back to ground level each winter, returning fresh and vigorous each spring.
This little beauty forms compact rosettes of leaves and produces clusters of small white flowers that brighten up the garden in late spring to early summer. While it may not win any awards for showiness, its understated elegance and rarity make it a true collector’s gem.
Where Cody’s Rockcress Calls Home
Cody’s rockcress is native to some of North America’s most pristine wilderness areas, including Alaska, British Columbia, and Yukon Territory. This plant has adapted to life in harsh northern climates where summers are brief but intense, and winters are long and cold.
Important Conservation Note
Here’s something crucial every gardener needs to know: Cody’s rockcress has a Global Conservation Status of S1S2Q, which indicates it’s quite rare and its status is somewhat uncertain. This means if you’re lucky enough to find this plant available, make absolutely sure it comes from responsibly sourced, ethically propagated stock. Never collect plants from the wild, and always purchase from reputable native plant nurseries that can verify their propagation methods.
Perfect Spots for Cody’s Rockcress
This northern native thrives in specialized garden settings where its unique needs can be met:
- Rock gardens with excellent drainage

Planting and Care Tips
Growing Cody’s rockcress successfully is all about mimicking its natural Arctic habitat:
