What is Alaska Draba?
Alaska draba is a native North American herbaceous plant that belongs to the mustard family. As a forb, it’s a non-woody perennial that forms low-growing mats or cushions, making it an excellent ground cover option. Don’t let its diminutive size fool you – this plant is incredibly hardy and can thrive in conditions that would challenge many other garden plants.
Where Does Alaska Draba Call Home?
This remarkable plant has an impressive native range across North America. You’ll find Alaska draba naturally growing throughout Alaska, western Canada (including Alberta, British Columbia, Yukon, and Northwest Territories), and several western U.S. states including California, Nevada, and Washington. Its widespread distribution speaks to its incredible adaptability and hardiness.

Growing Conditions and Care
One of Alaska draba’s greatest strengths is its ability to thrive in challenging conditions. Here’s what this hardy plant prefers:
Sunlight: Full sun exposure brings out the best in Alaska draba, though it can tolerate some light shade.
Soil requirements: Well-draining soil is essential. This plant actually prefers lean, rocky, or sandy soils over rich garden soil. It’s quite tolerant of poor soil conditions.
Water needs: Once established, Alaska draba is quite drought tolerant. Avoid overwatering, as this can lead to problems.
Climate considerations: This plant is incredibly cold hardy and can handle harsh winters with ease. It’s suited for USDA hardiness zones 2-7.
Planting and Establishment Tips
Getting Alaska draba established in your garden is relatively straightforward:
- Plant in spring or early fall when temperatures are moderate
- Ensure excellent drainage – consider adding gravel or sand to heavy soils
- Space plants appropriately to allow for their spreading habit
- Water regularly during the first growing season to help establishment
- Once established, reduce watering frequency significantly
- Avoid fertilizing – this plant prefers lean conditions
Supporting Pollinators and Wildlife
While Alaska draba may seem modest, its small white flowers provide important early-season nectar for small native pollinators. The plant typically blooms in spring, offering sustenance when few other flowers are available. This makes it particularly valuable in native plant gardens focused on supporting local ecosystems.
Is Alaska Draba Right for Your Garden?
Alaska draba is an excellent choice if you’re looking for a low-maintenance, drought-tolerant native plant that can handle challenging growing conditions. It’s particularly well-suited for gardeners in colder climates who want to create rock gardens, alpine displays, or naturalized areas with minimal upkeep.
However, if you’re seeking a showy centerpiece plant or something that thrives in rich, moist garden soil, you might want to consider other options. Alaska draba’s beauty lies in its subtle charm and remarkable resilience rather than dramatic visual impact.
By choosing this hardy native, you’re not only adding an interesting and adaptable plant to your landscape but also supporting the indigenous flora that makes North American gardens truly special.
