I received a clump of it from a friend last fall. It didn't develop a plume last fall nor does it look like it will this year.

Perhaps this link will help you determine a genus. I forgot I had this bookmarked. There are quite a few cultivars now also.

That is my best answer where grasses are concerned...if the first one isn't correct, use the shotgun approach. Whistling

If you can say how tall it is (more precisely than "fairly tall" Smiling ), and how wide the leaf blades are, and also provide a close-up to show the leaf variegation, it might be possible to narrow it down to the more likely candidates, though flowers would cinch it... given that it doesn't look like any stems/culms are visible? If there are any, though, a photo would be useful.

Working on it...Plant is 50 in high and about as wide; individual leaves are slim, widest avg. 3/8th in wide.

Will try for better illustrations tomorrow.

My guess would be Miscanthus 'Morning Light'. What zone are you in and when does it leaf out? I'm in 5B (SE Mich) and mine leafs out pretty late... my miscanthus leaf out a lot later than my Calamagrostis 'Overdam'... I can't give exact times, but it's probably late April for Overdam vs. early June for Morning Light and the other miscanthus I have.

You can be fairly certain that it is a Miscanthus sinensis cultivar. Some are shy bloomers in the north. It would be pretty difficult to narrow it down to an exact cultivar, even when in bloom. Only some of them are distinct enough for "easy" identification. There are differences, of course, but they are hard to describe and observe unless you have the different cultivars growing next to each other.
