Grossmont College put this in a couple of years ago and the invasiveness of this plant is quite evident.

I planted this a few years ago and after a couple of years, it was evident to me that it was invasive. I pulled it out and am keeping an eye out for new starts, and pulling them up. This plant can get away from you quickly. Glad to see it on the invasive list.

In your list of recommended alternatives, Muhlenbergia cappilaris' discription includes "Adverse Factors: May self sow". Can you please tell me how difficult is it to keep under control? I think it is a lovely plant and think it will look great on my foothill property. Thank you for sharing the alternative List.

Haven't seen this plant as a threat to pasture grasses here in Texas. I definitely consider your information as a warning though! Any research/information on this species in Texas?

This was recommended to me by a nursery in that it is a true grass. My mentally ill neighbor dumped a huge amount of bread leaf weed killer in my yard and I thought that I could use an ornamental grass to deal with the problem until the effects of the pesticide gradually disappeared. Are there other true grasses that are not as invasive that I could use.

How can I tell if this is growing in my yard? Just compare to an internet picture?

Hi John,  
You can e-mail a photo of the grass in your yard to your local UC Master Gardener Program (mg.ucanr.edu) and a volunteer will be able to help or you can bring a sample into your local UCCE office.

I live in Northern New Mexico. I began with 1-2 Mexican Feather Grasses 10 years ago and now have dozens all over my yard. They are beautiful here but are invasive. I pull hundreds of seedlings each year. I also comb the grass when they set their seed heads to reduce seedlings. Combing works well on this plant and also removes dead growth. My yard would not be as beautiful without these stunning grasses.

I for one believes that Mexican feather grass is beautiful.  
Deer grasses, mulenbergia capilaris and mulenbergia rigens both look shabby after two years. Shame on you, PlantRight for discriminating  
against a perfectly beautiful grass with flowing feathery stems that sway in the breeze. Keep your Mulenbergia and stop cutting off the supply of Mexican feather grass to nurseries!!!!!!

Hi Glenda,  
 
We understand your love for Mexican Feather Grass and we agree with you that it is indeed a beautiful plant. While Mexican Feather Grass is beautiful you can not simply ignore the potential impact that it has as an invasive. It is a vigorous grower that crowds out native grass species, putting California's diverse landscape at risk. PlantRight and the UC Master Gardener Program work hard to make sure the choices we make in our home landscapes are sustainable and don't negatively effect our fragile environments. If you would like to contact me directly to discuss feel free to email me at mgwomack@ucanr.edu.  
 
Best,  
Melissa

This stuff is terrible. Some Mexican feather grass was originally planted in some landscaped areas on my property and now it has invaded and taken over, displacing the original grass. I try to pull it wherever I see it growing, but once it has invaded the lawn area it seems almost impossible to get rid of it since it intertwines itself with the original grass.

I was wondering if it is invasive in pahrump nv or is it a plans I will actually be able to keep alive here? We are zone 8 I believe.

Hi Fawn,  
 
It would be best to contact your local Master Gardener Program in Nevada. They would have more info about Mexican Feather Grass and if it has invasive characteristics in your area. https://www.unce.unr.edu/programs/sites/mastergardener/

we live in an oak woodland in the hills of Templeton, Ca. We are on a well and with the drought, it is tough to keep anything alive. We have some of this; it lives, looks pretty, and has never spread.

Native grasses the key word. Californians have this prejudice about plants that have were sowed a couple of hundred years ago; refuse to call them native plants. My rule of thumb is it doesn't grow it was never intended to be a native plant. You can stop propagation by cutting back its flowers before they go to seed.. simple enough.  
Today I bought 5 of these plants for my landscape that can take full hot sun that don't attract hornets to nest. Need to go back tomorrow and get more before the 'edict' reaches this state.

I live on Long Island and planted the grass over 2 years ago.  
While it's grown and looks beautiful, it has not spread at all. In  
fact I planted 4 more last year and only 2 have taken. I appreciate  
your concern for where you live, but apparently this is not the  
problem in the northeast. Maybe you can try and limit distribution  
to the states where it is known to be invasive so the rest of us  
can enjoy this beautiful plant.

Invasive it may be here in SoCal but it will grow where nothing else will. So choose weeds, bare dirt or Feather Grass. I dont find it invasive in urban gardens if you crewcut the ends before the seeds can fly out. It is beautiful IMHO. No water needed either.

Sure wish someone had told my designer about this before our garden installation last year. Spreads insanely fast in C zone 9B. Grrr.

I'd like to add a note for those outside CA asking about this grass. While Nassella tenuissima is an invasive species in California, this grass is native to west Texas and southern New Mexico. More specifically, this grass is native to the trans-Pecos mountain region of the Chihuahuan Desert.

What is the problem with it mixing in my lawn ? With my female dogs all I have is blotches of different kinds of grass

Hi Steve, There are other beautiful lawn alternative options that would work for your space and dogs. You can search here for inspiration: http://arboretum.ucdavis.edu/plant_search.aspx. Best, Melissa

I was pulling this Mexican feathergrass out and one of the strands penetrated my glove and lodged into the side of my ring finger. I pulled a piece out but not sure I got all of it. Finger is very swollen and cannot straighten it. Any recommendations besides a trip to see some physician?? I’m not too fond of them at the moment.

I just planted a lot of this in my yard to compliment a fountain. I had no idea this was a harmful plant. From the comments it appears this is a problem for those in warmer climates. I live in virginia’s.... do you think I will be ok or should I take them out?

I would check with your local program in Virginia - since your climate is so different than California's. Virginia Cooperative Extension would be able to guide you on if it is invasive in your area: https://ext.vt.edu/lawn-garden/master-gardener.html.

I just planted 4 feather grass in our driveway circle in W TX. Our lawnis badically dirt and rocks so Ihope the grass spreads that way. It might help eliminate dust.

Hi Sharon, I would recommend looking into a mulch for that area to help keep the dust down: http://bit.ly/2xrIvT8. Best, Melissa

This stuff is a pain in the neck in Orange County Ca. The seeds create a thick mat that sticks to everything. If you have mulch or ground cover bark you won't see it after this stuff piles up. I agree it is very pretty. I read one comment about combing. I do this with a wire brush every week for a about 5 weeks from the middle of May through June for about 8 plants. It produces a 5 gallon bucket of seeds and threads. I still get new growth everywhere including all of the joints and cracks in my pavement. This stuff is all coming out this fall.

my neighbor has planted these everywhere, I live in Southern California, it has ruined my lawn and is now growing on my other next door neighbors side, so I'm surrounded. I don't know what to do

2 years ago I salvaged about 8 small plants from a nearby golf course and planted them in an area where lawn grass was removed and turned in to a drought tolerant area. After 1 year and hundreds of new plants sprouting, I dug them up and moved them to a bare area in my front yard. Big mistake as there are now hundreds of new plants there, growing vigorously in an area where 3 ground covers have failed. I have a feeling that neighbors are going to hate me so I will be doing the Roundup thing. And, the area they were taken from last year has dozens of new ones coming up. BTW, I’m in northern San Diego county.

This plant grows all over central Alberta and it is very dangerous for dogs. The seeds are pointed and they get stuck in between the dogs paws and if they're not noticed they can work their way under the ten der skin and cause massive infection. Give your dogs paws a quick once over between the pads if they've been out running in this stuff.

Hi I live inEdmonton Alberta so should I return to store ?

Hi Dana, I am only familiar with it being an aggressive grower and invasive in California. I would check with the Master Gardener program in Alberta: https://www.mgaab.org/.

My neighbor planted this years ago. I finally "took over" helping her with her small property and immediately removed it. The following years, I removed over 200 "plugs" that appeared o the property...and it was only 15'x30'. Yikes. HATE the stuff.

We were warned by our landscaper that the seeds from this grass are very dangerous to dogs so we pulled out our. A neighbor has quite a few and my small dog was sniffing around and got these tiny seeds up his nose. Not sure what to do.

Hi Pam - So sorry to hear that happened! You should contact your veterinarian if you have any concerns about your dogs health. I hope that he is ok. - Melissa
