I don’t think they would stabilize to any great degree on their own. Look at native Carex species.

do they spread by root?

Carex? They spread by clumps, either via stolons, roots or rhizomes.

i 1st became aware of loriopi while living in nawlins.' people used it as a sidewalk border. most lawns were st augistine grass & if left unchecked the st augustine would carpet right over sidewalks. at that time i knew it as monkey grass. i have loriopi along my driveway & after 7 years it has started to creep. i researched carex & it looks like a good choice. the

Carex pensylvanica looks like a good choice for me. thanks for the suggestions. a couple garden supplies have it on sale now so the timing is right. the area that is eroding is under a hackberry tree so the carex would be happy in the shade there. it's in 3.5" pots so i'll need at least $200.00 worth as it spreads slowly. i'll eventually get some for my front yard to put in the shade of my magnolia tree. i'm getting older & finding it harder to keep up with the weeds. i'm having a major battle with creeping charlie in some areas. i have a neighbor who barely keeps his grass mowed & his yard is the source of the creeping charlie. i've been putting a metal barrier at the base of my fence as i can afford it.

it has become my number garden enemy next to nut sedge. it brings to mind when someone on these forums asked what to do about nut sedge on these forums several years ago one member suggested moving

Just want to chime in and say I love liriope. I had it in perennial border and it was a very nice, neat low mound of grass-like foliage. I had the clumper L. muscari, not the creeper L. spicata. Carex are also nice, too, although my only experience has been with "Ice Dance". Both L. muscari and Carex "Ice Dance" spread at a nice clip for me, but not overly aggressively.

Liriope is used as an office park planting around here, along with cherry laurels, etc.

I suggested the Carex genus as it is a host plant for native butterfly and moth species. Read about it in ”Horticulture” and have it on my list for some tough areas.

Rober, i would investigate getting the plants as plugs, that may be even more affordable.

I understand your frustration; I am sandwiched between two neighbors who do jack squat with their yards so I’m fighting garlic mustard and periwinkle among other noxious plants. I’d be happy if they planted bee lawns and mowed twice a year, but given their current ”stewardship,” they need to move into condos and leave yards to people who give a crap.

he same guy with the weeds has an above ground pool. when he drains it he washes out the eroded area. i finally got him to run a hose to the other side of his property. my land isn't that steep but in a hard rain i could kayak down the property. another contributor are mole tunnels. water runs in on the high end & exits as a ditch. i've trapped around 40 moles over the last 5 years.

where would i find plugs of carex?

Prairie moon nursery offers them, don't know which Carex. You may want to speak to local nurseries as well, they may order them for you from their suppliers if you need enough.

i thought i's posted this must have hit a wrong button. i found a supplier that offers 3" pots for $1.40 with $150.00 minimum purchase. next closest price was 6.95. plug suppliers were all out of stock.

good story about the pool. for several years the pool was an unattended stagnant mess. ducks would take a break in their travels in the pool. i bought 3 dozen minnows & put them in the pool to eat the mosquito larva. 2 years ago they decided to clean it up, the woman told me that the ducks must have eaten minnows & pooped out minnow eggs because they found minnows in the pool.

That sounds like a good price.

And the stupidity of people never fails to amaze me.
