Stipa tenuissima

Although it reseeds freely as others have mentioned, I find the seedlings easy to pull out. Even the larger ones can be removed or transplanted without much effort. If you are trying to maintain a very neat landscape, this plant is probably going to drive you crazy. If you like a more naturalized look as I do, you may really like it. It fills in the areas around my other plants, but doesn't choke them out. It reminds me of the California coast, which is the look I am going for in our front yard. As others have said, don't plant where your dog might get into it.

plant grows well here ,'west mesa in albuquerque. no problem with reseeding have divided to get four new plants. Looks good in winter.

I live in the Dallas, TX area & planted one in 2007. I now have several that I've re-potted from baby plants. My main plant did die after an awful frost last year, but left its babies and I was thrilled. YES, they do re-seed very easily but are so easy to pull out when very little if not wanted. I don't consider them invasive for this reason. I love watching the gentle peaceful swaying in the wind of this plant. I've given several away. I have only 3 in the ground and several in pots right now.

I put one of these in a small backyard garden because I liked it visually and the way it moves in the wind. I thought it a harmless carefree addition. You'd think it ideal for Xeriscape or rock gardens. However it reseeds like crazy, and this from just one plant. Put 4 -5 or more in and you will have alot of extra work on your hands come early spring. I'll be sure to research before I try any other ornamental grasses. Proceed with caution with this choice.

My dog chased her tennis ball into an area of our yard where this plant is proliferating. She had several of the hairs stuck in her eyes and they caused her eye to swell shut. It has also somehow affected her jaw and given her a form of "lock jaw" and the veterinarian thinks she may have contracted tetanus from it. I am pulling it out and would not recommend it in a yard with active dogs.

beautiful sensuous grass which adapts to a variety of conditions, sun, part shade, dry poor soil. Reseeds and spreads but not difficult to control.

My landscape designer suggested this grass, and I think it is really lovely to watch blowing in the wind. However, it was planted next to my swimming pool, and the seed threads pass through my filter baskets and clog my impeller. I have to clear it out daily, even though I go out every morning and strip as much seed off of the plants as I can. I'll probably have to dig up the plants, and hope they don't sprout on the other side of the back yard wall, in the desert.

I will agree with most of the aforementioned statements , durable , beautiful and so on . But I also see that it is labeled as INVASIVE . I capitalize that with good reason . Here in the southwest desert and this is not a native plant . I planted 6 of them and now have had 100's of them all over my property (4 acres ) in an area that recieves less than 10 inches of rainfall a year and this stuff is sprouting up with no irragation . More so in areas that does . Once released it will scatter more than likely and add more fuel to already disastrous wildfires .

This grass looks like a clump of hair, dancing in the breeze. Soft green in spring, then turns a soft beige in the hot summer, and I leave it uncut in winter to provide interest. It does re-seed fairly heavily, but unwanted volunteers are easily pulled. I grow it pretty dry in my xeriscape area, in clay loam low in organic material. Survived a dry cold winter quite well. The description says 24-36" height -- I've never seen it get taller than 6-8", even at the Denver Botanic Gardens. Maybe because we grow it dry in the Rockies?

I really loved the look of this grass in our landscape. It grows quite well in the desert southwest with some irrigation. But beware if you have puppies that like to grab at anything that moves. One of our puppies grabbed at some seeds/feathers that had fallen to the ground and nearly choked while trying to swallow them. We were unable to find any in it's mouth to remove, so I don't believe it had very much.
Also, this plant is a favorite of jackrabbits, so it's best grown behind a fenced area or chicken wire.

I grow this grass in a pot, and bring it in for the winter. I also start it in the ground, dig it up, and bring it into the house to overwinter. That way, I get the lovely bloom although my season is too short for it to bloom outdoors. Last year's pot plant is blooming no - in early April, in my sunroom.

this was one of the first plants I put in my new garden because it is so beautiful in the wind and I am in a windy area. It did very well even through our cold winter but I fear I have baby's all around it! will try and transplant them to my other garden. did well in composted heavy clay and was watered by drip only once a week even in hot weather.

Other common names for this grass that is native to California, New Mexico, Texas, Mexico, and Argentina: ponytail grass, horsetail grass, horse tail grass, hair grass, angel hair grass, angelhair grass, finestem needlegrass

I have grown Mexican feather grass in a large container and did not have a reseeding problem; however, this may be atypical. It appears it will self-sow more prolifically in moist areas and is not as bothersome in dry locations. It mysteriously died sabout 5 years ago. This spring, a new plant emerged in the container in which the old plant had been growing. I am extremely happy that I have been blessed with this gift because I had missed the plant very much after it died.

My comment is postive based on growability in the Central Valley of California. The only thing I don't care for, my wife loves it, is it sows itself all over the place. Otherwise a very durable plant.

San Antonio, Tx.
One is growing in a huge container and from the top it looks almost like a huge green wig. I bought it at Walmart as a small plant and it has grown quite rapidly. Its blades blow in the wind so gracefully that it provides a soothing effect. It has withstood 22 degree nights in the winter and 108 degrees for 2 days this summer.

The hardiness of this grass seems to depend on the age. Clumps that have not flowered are much hardier, making this a biennial for me. Usually the clumps that have flowered do not survive the winter.

The flower stalks and seeds are very sticky so that seeding around is very common.

Seeds sprout in mid to late spring outdoors.
