Hi Karin, I was looking through the unanswered questions and came across yours. I just planted my beauty less than a week ago. Here she is in some mid-day sun.

My hosta ID skills are terrible, but here goes. Your hosta looks blue, but that could be the light. Flower Power has super tall scapes, is vase shaped, but green. Your hosta looks more rippled than FP, too.

It's Krossa Regal

It looks very green in the sunlight. I just planted this hosta which came from a nursery, not a box store. Here’s another shot.

Funny to see old pictures...

This hosta has changed through the years and now I know that it is Krossa Regal :-)

It is interesting to watch them grow. I checked the pictures from 2016 again and found this...

This year I divided it because a friend wanted a piece and had this in spring:

I tried one in a sunny spot and it is doing good

and one at it's old place in the shade

I like Krossa Regal and other vase shaped hosta, they look good in the background.

Regal Splendor has the same long flower scapes
