I've sunk it in the ground, among other perennials in three gallon pots. I guess I'll find out if its notorious roots will escape the drainage holes in the pots. I suppose I'll have to remove it from time to time to divide it. I think it might look good in a pot up near my dark purple front door this year, too.

This species is naturalized through most of North America, and often forms large monoculture stands in wetland habitat. Cultivating it is prohibited in Massachusetts, where it's considered an invasive threat to natural habitat. It's been declared a noxious weed in Washington, and invasive in Connecticut.
I've had a variegated ribbon grass growing in a mostly sunny area for a bit over a year. Its home is next to my hose, so it probably get...Read Mores more water than most in the heat of the summer.
It doubled in size in a year, and I spaded a good portion out and moved it to a shady area about 10 inches wide between my air conditioning unit and a brick house. It transplanted nicely and I expect that I will have to maintain both patches regularly to keep it in check.
I do not live near wetlands, and in my small, Pittsburgh, PA garden, I give it enough attention that I don't see it becoming a nuisance. Ribbon grass has its purposes in my garden. If I were to move and the new owners of my house were not good at garden upkeep, I can see how this grass would take over-- something to consider for sure.
My positive rating reflects its visual appeal, manageability, and adaptability for my situation. I am willing to spade it when needed, shear it if it becomes gangly, and contain it should I need to. The only things to border my small property are neighboring houses, and I don't see it taking over those! If it is invasive in your area, by no means should it be planted. There are many wonderful varieties of grass, so do your research and choose one that suits the needs of your garden and your community.

A healthy clump developed, very ornamental, but it was too tall (5 ' ) and wide for its spot. I divided it and moved it to a dry slope with poor soil and competition from tree roots.

As a side note, the tall blooming stalks make great cat toys!

For that reason, when we move, I'm leaving it. I'll find a similar grass that is less invasive.

Others who have listed information on the plant have said it is terribly invasive and its even outlawed in some states! I believe it could be invasive in ideal conditions and in other zones, however, I will give you comments of my experience with it in Zone 5. In Zone 5 it seems to behave.
I've never really had any trouble with it. In fact, I sometimes wish it would be more invasive and fill-in faster. That being said - I do have it planted in my PROBLEM spots, so that must help keep it contained. When all other plants fail for me in a spot, I try the ribbon grass there - I use it as my problem solver plant.
It's never traveled for me more than the clump getting larger or a few springs here or there. Its easy to contain each spring if a few springs wander close by - just dig out what you don't want . It doesn't form those woody tough roots which are impossible to dig up - as some grasses do (at least in zone 5, it doesn't ). It produces seeds, but I've never had it pop up in any area of my yard where it wasn't planted
My experience in Zone 5 in different types of soil and sun:
Clay - Impossible, thick & wet - semi-shade: it grows well and is not invasive.
Moist Loamy soil - shade to semi-shade and under trees in shade garden row: it grows well and is not invasive.
Dry, Hot Sun: grows slowly, but well.
Dry Shade or Semi-Shade - under trees - does not grow well - it will grow, but it is very, very sparse, and a little sickly looking - however, it comes back each year - it just doesn't thicken up, so its not as pretty.
I've never planted it in a moist sunny area as those spots in my yard are short in supply and I use them for other perennials, so I can't address those conditions - but perhaps there - in zone 5 - it could become invasive.
Ribbon Grass gets taller through the summer & stays green & white. In the winter it turns straw colored and wilts down. You can either cut in back in the late fall or leave it be. It is best to transplant it in the spring before it gets too hot. It is considered a cool season grass, which I assume means it grows fastest in the spring. It dies back in the winter and will poke up in the spring through all the dried grass from the season before.
Last year I planted a few springs of it in pots with my annuals and it looked great! I expected it would die over the winter in the pots, but it came back, I was so surprised it would survive above the freeze line.
The Minnesota DNR has Reed canary grass (Phalaris arundinacea) listed on it's invasive species list.
"Ecological Threat: ...Read Morer />
* Reed canary is a major threat to natural wetlands. It out competes most native species.
* It presents a major challenge in wetland mitigation efforts.
* It forms large, single-species stands, with which other species cannot compete.
* If cut during the growing season a second growth spurt occurs in the fall.
* Invasion is associated with disturbances, such as ditch building, stream channeling sedimentation and intentional planting.
* This Eurasian species has been planted throughout the U.S. since the 1800s for forage and erosion control. It is still being planted."

Island bed meant that the garden bed is surrounded by lawn or hard landscape features - but it's alway best to reduce the number of cracks or spray weed killer once in a while if it tries to sneak through the cracks of the hard landscape features.(hard landscape features meant brick paths, paved stone paths, concrete, etc). Otherwise, it is not a good plant for most landscape features - it grows too aggressively for most species of plants, choking them out. Also it is hard to weed out other grass species out of the patches.
I still have tiny patches of ribbon grass popping up since I have tried to get rid of the whole thing. That tell you how hard it is to contain this species if you are trying to include it in a mixed bed, formal beds, etc.

The variegated forms are less invasive but produce viable seed. They can be quite beautiful in early season growth. Planting these is not justified by the potential destruction of wetland habitat. With global warming Phalaris has the potential to overwhelm habitat elsewhere in the US.

We call it ribbongrass, which is what my great-grandmother called it when she gave us starts of it from her garden. I know she had grown it for a very long time, because she talked about growing it on the banks of the Siuslaw river, where she raised her children, close to seventy years ago. She was very proud of her striped grass, and a varieagated holly, and was sad that after they moved, the relative who bought the house destroyed all the varieagated plants because he thought they were diseased.
