Ascherson’s Orchardgrass: A Lesser-Known Perennial Grass
If you’ve stumbled across the name Ascherson’s orchardgrass (Dactylis glomerata aschersoniana), you’re looking at one of the more obscure members of the grass family. This perennial graminoid – that’s fancy talk for grass-like plant – is a bit of a botanical mystery that deserves a closer look.
What Is Ascherson’s Orchardgrass?
Ascherson’s orchardgrass is a perennial grass that belongs to the broader orchardgrass family. You might also see it listed under its synonym, Dactylis aschersoniana Graebn. Like other grasses in its group, it’s a graminoid, which includes not just true grasses but also sedges, rushes, and other grass-like plants.
This isn’t a native plant to North America – it’s been introduced from elsewhere and has managed to establish itself and reproduce on its own in the wild. That means it’s naturalized but not originally from here.
Where You’ll Find It
Currently, Ascherson’s orchardgrass has been documented in New York state. Its limited distribution suggests it’s either a recent introduction or perhaps not as aggressive at spreading as some of its grass relatives.
Should You Plant Ascherson’s Orchardgrass?
Here’s where things get a bit tricky. While this grass isn’t listed as invasive or noxious, there’s still a lot we don’t know about its behavior in gardens and landscapes. As a non-native species, it’s worth considering whether there might be better alternatives that support local ecosystems.
Consider Native Alternatives
Before jumping into planting Ascherson’s orchardgrass, you might want to explore native grass options that could provide similar benefits while supporting local wildlife. Native grasses are typically better adapted to local conditions and provide food and habitat for native insects, birds, and other wildlife.
Some excellent native grass alternatives to consider include:
- Little bluestem (Schizachyrium scoparium)
- Buffalo grass (Poaceae species native to your region)
- Native fescue varieties
- Regional sedge species
The Bottom Line
Ascherson’s orchardgrass remains something of an enigma in the gardening world. While it’s established itself in New York and appears to be a well-behaved perennial grass, the lack of detailed information about its garden performance, ecological impact, and specific growing requirements makes it a bit of a gamble for home gardeners.
If you’re set on trying something unique in your landscape, this grass might fit the bill. However, for most gardeners, exploring the rich diversity of native grasses in your area will likely provide better results and greater ecological benefits. Native plants are generally easier to grow, require less maintenance once established, and create habitat for local wildlife – making them a win-win choice for both gardener and environment.
