Common Woodrush: A Hardy Native Grass for Cool Climate Gardens
If you’re looking for a tough, no-fuss native plant that can handle whatever Mother Nature throws at it, let me introduce you to common woodrush (Luzula multiflora frigida). This unassuming little perennial might not win any beauty contests, but what it lacks in flashy flowers, it makes up for in pure, stubborn resilience.
What Is Common Woodrush?
Common woodrush is a perennial grass-like plant that belongs to the rush family (Juncaceae). Don’t let the grass-like description fool you into thinking it’s boring—this hardy little survivor has been quietly thriving in some of the harshest climates on Earth for thousands of years. It forms small clumps and produces clusters of tiny, brownish flowers that might not stop traffic, but they get the job done when it comes to reproduction.
Where Does It Call Home?
This cold-loving character is native to an impressively vast territory. You’ll find it naturally occurring across Alaska, throughout Canada (including Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island, Quebec, Saskatchewan, Yukon, Northwest Territories, and Nunavut), Greenland, and even scattered across many U.S. states from the mountainous West to the chilly Northeast. We’re talking about everywhere from Arizona and California to Maine and Vermont, with stops in Colorado, Idaho, Montana, Nevada, New Hampshire, New Mexico, New York, South Dakota, Utah, Washington, and Wyoming.
Should You Grow Common Woodrush?
Here’s the honest truth: common woodrush isn’t going to be the star of your garden show. But if you’re dealing with challenging growing conditions—think cold winters, poor soil, or areas where other plants throw in the towel—this might be your new best friend.
You’ll love common woodrush if you:
- Garden in USDA hardiness zones 2-6
- Want a truly low-maintenance native plant
- Need groundcover for naturalistic or alpine garden settings
- Appreciate plants that support local ecosystems
- Have challenging sites with poor soil or harsh conditions
You might want to skip it if you:
- Live in hot, humid climates
- Prefer showy, colorful flowers
- Want fast-growing plants for immediate impact
- Garden primarily for attracting pollinators (it’s wind-pollinated)
Growing Common Woodrush Successfully
The beauty of common woodrush lies in its simplicity. This plant has survived in some of the toughest environments on the planet, so your garden conditions probably seem like a luxury resort in comparison.
Growing Conditions:
- Light: Full sun to partial shade (quite adaptable)
- Soil: Well-drained soil; tolerates poor, rocky, or sandy conditions
- Water: Consistent moisture preferred, but drought-tolerant once established
- Temperature: Thrives in cool climates; struggles in hot, humid conditions
Planting and Care Tips
Once you get common woodrush established, it’s pretty much a plant it and forget it situation. Here’s how to set it up for success:
- Planting: Spring or early fall planting works best
- Spacing: Give plants about 6-12 inches apart for groundcover effect
- Watering: Water regularly the first year, then reduce frequency as it establishes
- Fertilizing: Skip the fertilizer—this plant prefers lean conditions
- Maintenance: Minimal pruning needed; remove dead foliage in spring if desired
Perfect Garden Partners
Common woodrush plays well with other cold-hardy natives and alpine plants. Try pairing it with native sedums, wild bergamot, or other mountain and northern plants that share its preference for cooler conditions and well-drained soil.
The Bottom Line
Common woodrush might not be the most glamorous plant in the native plant world, but it’s definitely one of the most reliable. If you garden in a cold climate and want to support native ecosystems with minimal fuss, this hardy little survivor deserves a spot in your landscape. Just remember—it’s all about setting the right expectations and appreciating plants for what they bring to the table, even if that table happens to be covered in snow half the year!
