Tick Quackgrass: What Every Gardener Should Know About This Non-Native Grass
If you’ve stumbled across the name tick quackgrass in your plant research, you might be wondering what this somewhat oddly-named grass is all about. Scientifically known as Thinopyrum pycnanthum, this perennial grass has an interesting story that every native plant enthusiast should know.



What is Tick Quackgrass?
Tick quackgrass is a perennial graminoid – that’s botanist-speak for a grass or grass-like plant. Like other members of the grass family, it’s a monocot with the characteristic narrow leaves and fibrous root system you’d expect. However, there’s an important detail that sets this species apart from many of our beloved native grasses.
The Non-Native Reality
Here’s where things get interesting (and a bit concerning): tick quackgrass isn’t actually native to North America. This European transplant has established itself across various regions and now reproduces on its own in the wild without any human help. It’s what botanists call a naturalized species – essentially, it’s made itself at home whether we invited it or not.
Where You’ll Find It
Tick quackgrass has spread across a surprisingly wide range of North American locations. You can find established populations in:
- Canadian provinces: Alberta and Nova Scotia
- Northeastern states: Maine, Massachusetts, New Hampshire, New York, Pennsylvania, Rhode Island
- Western states: Oregon, Washington
- As far south as Texas
Wetland Connections
One notable characteristic of tick quackgrass is its relationship with wet areas. Across all regions where it’s found, this grass has a Facultative Wetland status. In plain English, this means it usually hangs out in wetlands but isn’t picky enough to avoid drier spots when the opportunity arises. This flexibility might help explain how it’s managed to establish itself across such diverse geographic areas.
Should You Plant It?
Here’s where we need to have an honest conversation. While tick quackgrass isn’t currently listed as invasive or noxious (at least in available databases), its non-native status gives us pause. As native plant advocates, we believe there are compelling reasons to look toward our homegrown alternatives instead.
The truth is, there’s limited information available about this species’ garden performance, care requirements, or ecological benefits. When you’re investing time and energy into your landscape, why not choose plants with proven track records that also support local ecosystems?
Better Native Alternatives
Instead of tick quackgrass, consider these fantastic native grass options that will give you beauty and ecological benefits:
- For wetland areas: Try native sedges like fox sedge or bladder sedge
- For prairie-style plantings: Little bluestem and buffalo grass are stunners
- For coastal areas: Beach grass species native to your region
- For general landscaping: Native fescues and bunch grasses
The Bottom Line
While tick quackgrass might not be the villain of the plant world, it’s not exactly the hero of your native garden story either. With so many gorgeous native grasses available that support local wildlife, improve soil health, and provide stunning seasonal interest, there’s really no compelling reason to choose this European import.
If you’re passionate about creating landscapes that support local ecosystems while looking absolutely gorgeous, stick with the natives. Your local birds, butterflies, and beneficial insects will thank you, and you’ll have the satisfaction of knowing your garden is truly working in harmony with its environment.
Remember, every plant choice is a vote for the kind of landscape – and world – we want to create. Why not cast your vote for the home team?
