Looks like a kind of carex -- where do you live (that could narrow it down a bit)? Are the blades sharp (could they give you a "paper cut")? Is it evergreen? I think, with the right information, we can get you your answer in fewer than 20 questions. :)

It is a decorative/ornamental grass. Need dimensions and climate zone information for its locale to narrow it down. A google image search for dwarf decorative grasses could help you to find one that is exactly like the image or close enough to make you happy. Are you asking because you want to add it to your landscape? You will need to determine your climate zone & find plants that are hardy for that zone.

so, what are you looking for? Where do you live, what are you trying to achieve? We can help

Miscanthus sp. most likely sinesis var. Morning Light. Hardy in zones 5-9.

It's just an ornamental grass. There are dozens of them. Exact type doesn't matter. Go to a local nursery or big box home center and buy one. Simple.

I work with several varieties of Carex daily. Yes, it does resemble Carex socialis from what I can see in the photo. This is what I do know about the Carex gang.....they will not tolerate full sun. They are woodland plants. They are often used interchangeably with other shade requiring groundcovers such as liriope or ophiopogon as a preferred, native option, but not in place of most other sun loving ornamental grasses. After giving the picture a thorough period of study I concluded that nothing about the above photo said moist, shaded woodland environment to me. Additionally, though most Carex can reach up 24" tall, they do not regularly get larger than 8-10" in diameter. I just did not see what was depicted as a successful application for any of the Carex varieties with which I am familiar. Miscanthus does not typically bloom until August or early September, so my conclusion, with the info available was as stated. I am eager to discover the correct plant as I am often wrong. For me, this is how learning happens, so cheers to you for helping me exercise my brain.

Gardengal48: I said type doesn't matter because if she goes to a home center or nursery--as I suggested--she will face 2 facts:

1. There will be a limited selection.

2. They will be selling only what grows in her area.

It makes no difference what the grass is in the OP's photo. She'll have a few choices and that's all. The only variable that will affect her choice is light/shade, just like any other plant.

"There will be a limited selection."

Not necessarily true. Nurseries and garden centers in my area carry a wide variety of ornamental grasses - several dozen. And I am pretty sure we are not all that unique!! And there is this magical thing called "mail order".........which is how 95% of the gardeners in this world obtain plants which may not be readily obtainable in their area.

"They will be selling only what grows in her area."

And depending on where that might be, not much of a limitation at all!!

The point is that gardeners/homeowners request plant identification for a reason. Just telling them it is an ornamental grass and the type doesn't matter is not particularly helpful..........So yes, it does make a difference what kind of grass it is!

FWIW, there are 2000 different species of Carex and many of them love full sun and thrive in such a location!! So that is not necessarily a limiting factor. And the grass/sedge in the photo is not in full sun anyway. Also, unless a very dwarf cultivar, which 'Morning Light' is not, any miscanthus at this time of the season will be 3-4' tall. Or taller!!

To accurately identify any type of ornamental grass, one needs to see the individual blades clearly as well as the inflorescences/seedheads. This is really a question for the Ornamental Grasses or Name That Plant forums.

This looks like Lomandra longifolia. Possibly "Breeze" or "Lime Tuff".
