I think they might be the same. They may go from mini to small, the way my blue Mouse Ears has done over the years. (2' across with 3"w and 3"long leaves) . I have Dancing Mouse, but then after I read Chris' (Hallson Gardens) info on his Flamenco Mouse, I believe that his will remain smaller with the bit of quilting on the leaves. I just got it this year so I will be watching it. Many of the mice have disappointed me, with the exception of Mighty Mouse, which keeps its variegation and is a vigorous grower. Cat and Mouse just keeps reverting to all green for me. Snow Mouse disappeared. Holy and frosted are trying to hold their own here.

I've had 4 different mouse ear hostas. Blue, green, holy and frosted.

Blue has proven to be a spectacular grower. In 4 years my one starting plant is multiplied enough for me to give away several pieces and still have 3-4 small ones and one larger one.

Green mouse ears is growing slowly. Too slow to do much with, but it's hanging in there.

Holy is shrinking each year. This year it's only got 2 tiny leaves and I don't expect it to return again next year.

And frosted mouse ears didn't even make it through the first winter.
