Here is another more detailed photo with the pretty variegation/striping.

It looks like some form of Miscanthus sinensis...maybe var. condensatus 'Cabaret.' If it's 'Cabaret' it should be blooming now or soon.

It's common for Miscanthus to donut. It's a warm season grass, so you'll want to divide it in the early spring. Take your divisions from the healthy perimeter and discard the center.

Thanks for the quick response! I'm anxious to get started. Too bad I'll have to wait!

In the meantime, we can try for a positive ID.

Post a closeup of one or two of the most variegated blades, and give us a measurement of the width of a blade at its widest point.

Then post both medium and closeup shots of a flower, when it blooms. Wait until the bloom has been open for at least a week.

That should enable a good ID.

I shall do that tonight.

Here's a photo. The blades are 1" (almost exactly) and there are no flower buds evident anywhere. If anything, the stalks have tiny new blades.

Yep. It sure looks like 'Cabaret,' and measures up just right. This is what it should look like when it blooms:

Those new stalks look to me like the flower stalks.

It's a gorgeous grass, and well worth taking divisions next year.

Excellent...all the info I've read and photos I've seen pretty much match the Cabaret perfectly. The flowers look like that, if I remember correctly. And I agree, it's a beautiful grass and in DIRE need of division (the donuts are probably 2' in diameter). Can't wait to make the new divisions into a border! Again, thanks all for the help!
