This is a very nice Hosta, at first I thought the name was 'Seesower'
So I'm thinking, wow never heard of that one! Now I see its 'El Nino'. I got a small 'El Nino' last year as a free gift from a nursery that I put in a large order. I have another hosta which is a similar color and that is 'Tom Schmidt' they are both fast growers. Hopefully mine will be as big as your's real soon!
