Elymus dahuricus excelsus: A Little-Known Grass Worth Understanding
If you’ve stumbled across the name Elymus dahuricus excelsus in your plant research, you’re not alone in wondering what exactly this grass is all about. This particular member of the grass family falls into that interesting category of plants that exist in botanical literature but don’t have much fanfare in the gardening world.
What We Know About This Mysterious Grass
Elymus dahuricus excelsus belongs to the graminoid group, which is botanist-speak for grass or grass-like plant. It’s related to the wildrye grasses and has a botanical synonym of Elymus excelsus Turcz. ex Griseb., if you’re keeping track of scientific names (and who isn’t, right?).
The dahuricus part of its name gives us a clue about its likely origins – it suggests connections to the Dahurian region of northeastern Asia. However, specific information about its native range and distribution remains frustratingly elusive.
The Challenge of Limited Information
Here’s where things get a bit tricky for us gardeners. While this grass exists in botanical records, detailed information about its:
- Growing requirements and preferred conditions
- Mature size and growth habits
- Wildlife and pollinator benefits
- Invasive potential or native status
- USDA hardiness zones
…is simply not readily available in reliable gardening sources.
Should You Plant It?
Given the lack of comprehensive growing information and unclear native status, most gardeners would be better served choosing well-documented native grasses for their landscapes. Without knowing this plant’s invasive potential, environmental requirements, or ecological benefits, it’s hard to recommend it with confidence.
Better Alternatives to Consider
Instead of taking a chance on this botanical mystery, consider these well-studied native grass options:
- Regional native wildrye species (Elymus species native to your area)
- Local bunch grasses appropriate for your climate
- Prairie grasses with documented wildlife benefits
Your local native plant society or extension office can help you identify the best native grass species for your specific region and growing conditions.
The Bottom Line
While Elymus dahuricus excelsus might sound intriguing, the lack of available growing information makes it a risky choice for most gardeners. When it comes to creating beautiful, functional landscapes that support local ecosystems, sticking with well-documented native plants is usually your best bet. Save the botanical mysteries for the researchers, and choose grasses that come with clear growing guides and proven environmental benefits.
