Could it be 'Queen of the Seas'?

That's a good suggestion, thanks! I wonder about the color, though. I see many pictured with bluish leaves and mine is just green.

The blue phase for QotS is quite short, in my zone, anyway.

So maybe I missed it then.

I looked in the library and there several QOS that are very green. Then take a look and like Ken said compare the flowers. Good luck!

I thought Fluted Fountain before I saw you type that. I got Sea Drift this year and it looks like that. Does it have a nice tall structure to it?

Never mind, I just checked the flowers and they are lavender too.

maybe reptillian

Could be Reptillian as hosta_maker says which has white flowers. When it blooms that should help quite a bit. I did not notice if you said a color for the flower.

I just noticed the floweres in the pic, hard to see, I think ReptillIan is a good possibility. Has white flowers.
