Lovely hostas everyone! Karen, I bet you just have a mutated hosta. I have had several change on me. Here is a picture of one example of a changed hosta and two others that were all once identical plants.
The one in the far back is the changed hosta.
I've learned that trying to name NOID hostas is like trying to name NOID day lilies...just too many new varieties every year. I love them whether they have names or not, especially if the price is right.
Here are a few other hostas in my woodland area.
