×Elyhordeum chatangense: A Rare Arctic Grass Hybrid

If you’ve stumbled across the name ×Elyhordeum chatangense while researching native grasses, you’ve discovered one of North America’s more elusive botanical treasures. This perennial grass represents a fascinating intersection of two grass genera, but before you start planning where to plant it in your garden, there are some important things you should know about this arctic rarity.

What Exactly Is ×Elyhordeum chatangense?

The × symbol at the beginning of this plant’s name is your first clue that something special is going on here—it indicates this is a hybrid between two different genera. ×Elyhordeum chatangense is a natural cross between plants from the Elymus (wildrye) and Hordeum (barley) genera, creating something entirely unique in the grass world.

This perennial graminoid (that’s botanist-speak for grass or grass-like plant) belongs to the same family as familiar lawn grasses, but it’s adapted to life in some of the harshest conditions on the continent.

Where Does It Come From?

×Elyhordeum chatangense is native to Canada, specifically documented in Yukon Territory. This placement in the far north tells us everything we need to know about its preferred living conditions—think arctic tundra, not suburban backyard.

The Reality Check: Why This Isn’t Your Next Garden Addition

Here’s where we need to have an honest conversation about this intriguing grass. While ×Elyhordeum chatangense is undoubtedly fascinating from a botanical perspective, it’s not practical—or likely even possible—for most gardeners to grow. Here’s why:

  • It’s adapted to extreme arctic conditions that are impossible to replicate in most gardens
  • There’s virtually no information available about cultivation requirements
  • Seeds or plants are not commercially available
  • Its rarity means it should remain in its natural habitat

Better Native Grass Alternatives

If you’re interested in native grasses for your landscape, there are many wonderful options that are both more suitable for cultivation and readily available:

  • For northern gardeners: Canada wildrye (Elymus canadensis) or little bluestem (Schizachyrium scoparium)
  • For prairie-style gardens: Big bluestem (Andropogon gerardii) or prairie dropseed (Sporobolus heterolepis)
  • For woodland gardens: Pennsylvania sedge (Carex pensylvanica) or bottlebrush grass (Elymus hystrix)

The Takeaway

×Elyhordeum chatangense serves as a wonderful reminder of the incredible diversity that exists in the plant world, even in seemingly harsh environments like the Canadian arctic. While you won’t be adding this particular grass to your garden anytime soon, its existence highlights the importance of preserving natural habitats where such unique hybrids can occur and thrive.

Instead of seeking out this rare hybrid, consider supporting native plant conservation efforts and choosing well-documented native grasses that will thrive in your local conditions while supporting local wildlife. Your garden—and the broader ecosystem—will thank you for it.
