Labrador Bluegrass: A Mysterious Native Grass from the Far North

If you’ve ever wondered about the grasses that thrive in some of North America’s most challenging northern climates, you might be curious about Labrador bluegrass (×Dupoa labradorica). This little-known native grass represents one of nature’s hardy survivors, adapted to life in some of the continent’s most remote and rugged landscapes.

What is Labrador Bluegrass?

Labrador bluegrass, sometimes simply called dupoa, is a perennial grass that belongs to the graminoid family—that diverse group of grass and grass-like plants that includes true grasses, sedges, and rushes. The × symbol in its botanical name indicates that this is actually a hybrid species, making it even more unique in the plant world.

This hardy perennial has adapted to survive in conditions that would challenge most other plants, making it a true testament to nature’s resilience in harsh northern environments.

Where Does Labrador Bluegrass Grow?

As its common name suggests, this grass calls some of North America’s northernmost regions home. You’ll find Labrador bluegrass growing naturally in Alaska, Quebec, and Labrador—areas known for their challenging growing conditions and short growing seasons.

Should You Consider Growing Labrador Bluegrass?

Here’s where things get interesting—and a bit challenging. While Labrador bluegrass is undoubtedly a fascinating native species, it’s also incredibly rare and poorly documented in horticultural circles. This presents both opportunities and challenges for the curious gardener.

The Reality for Home Gardeners

If you’re drawn to the idea of growing this unique northern native, you should know that finding seeds or plants will likely be extremely difficult, if not impossible, through typical gardening channels. This grass appears to be more of a botanical curiosity than a readily available garden plant.

For gardeners interested in native grasses with similar cold-hardy characteristics, consider these more readily available alternatives:

  • Canada bluegrass (Poa compressa)
  • Alpine bluegrass (Poa alpina)
  • Other native Poa species suited to your specific region

Growing Conditions (Based on Native Habitat)

While specific cultivation information for Labrador bluegrass is limited, we can make educated guesses based on its native range:

  • Climate: Extremely cold-hardy, likely suitable for USDA zones 1-3
  • Soil: Probably adaptable to various soil types, as northern grasses often are
  • Moisture: Unknown specific requirements
  • Sun exposure: Likely full sun to partial shade

The Bottom Line

Labrador bluegrass represents one of those fascinating native plants that reminds us how much we still don’t know about our continent’s flora. While it may not be practical for most home gardens due to its rarity and limited availability, it serves as an important reminder of the incredible diversity of native plants adapted to North America’s most challenging environments.

If you’re passionate about northern native plants, consider supporting botanical research and conservation efforts that help document and preserve rare species like this one. Sometimes the most valuable plants are those that remain wild and free in their natural habitats, contributing to the complex ecosystems they’ve called home for thousands of years.
