Beardless Rabbitsfoot Grass: A Little-Known Perennial Grass
If you’ve stumbled across the name beardless rabbitsfoot grass in your gardening research, you’re looking at one of those plants that seems to fly under the radar. Polypogon imberbis (that’s the fancy botanical name) is a perennial grass that’s made its way into California, though you won’t find much chatter about it in most gardening circles.
What Exactly Is Beardless Rabbitsfoot Grass?
Beardless rabbitsfoot grass is a perennial graminoid – that’s botanist-speak for grass or grass-like plant. You might also see it called simply rabbitsfoot grass, though that common name gets shared around with a few different species. It belongs to the same family as many of our familiar lawn and ornamental grasses.
This grass is what we call non-native to the United States, meaning it originally came from somewhere else but has established itself here and now reproduces on its own in the wild. Think of it as a naturalized immigrant in the plant world.
Where You’ll Find It
Currently, beardless rabbitsfoot grass has been documented growing in California. It’s one of those plants that seems to keep a low profile – not spreading aggressively enough to make headlines, but established enough to stick around.

The Information Gap
Here’s where things get interesting (or frustrating, depending on your perspective): there’s surprisingly little detailed information available about this particular grass. We don’t have solid data on things like:
- Its specific growing requirements
- How tall or wide it gets
- What kind of wildlife might benefit from it
- Whether it has any invasive tendencies
- Its hardiness zones
This lack of information isn’t necessarily a red flag – it might just mean the plant is relatively uncommon or hasn’t caught the attention of researchers and gardeners yet.
Should You Plant It?
Given the limited information available about beardless rabbitsfoot grass, it’s hard to make a strong recommendation either way. Since we don’t know if it has invasive tendencies or what its ecological impact might be, the cautious approach might be to explore other options first.
If you’re drawn to ornamental grasses (and who isn’t – they add such lovely movement and texture to gardens!), consider looking into native alternatives that are well-documented and known to support local wildlife. California has some beautiful native bunch grasses that could give you that same grassy appeal with known benefits to your local ecosystem.
The Bottom Line
Beardless rabbitsfoot grass remains something of a mystery plant – established enough to have a presence in California, but not well-studied enough for us to know much about its garden potential or ecological role. Sometimes in gardening, as in life, the plants that don’t make a lot of noise are the ones we know the least about.
If you’re specifically interested in this grass for research purposes or have encountered it growing wild, it might be worth connecting with your local extension office or botanical society to contribute to our understanding of this under-documented species.
