Well Pam! Of course I'm not relying on the lady in the office. But she is nice, isn't she?
I don't think mine is super shiny, either. I've had mine about five years. When I sent it to the DGer 3 years ago, she said she divided it into four, so I assume she had one of the four pieces in similar conditions. Mine came directly from Shady Oaks, when I was buying from them directly and not through your co-ops. But between the one I sent her that she divided into four, and the one a 'friend' sent her she divided into four, she had eight divisions to compare it to.
What we do in irises to determine if they are the same is purchase one of the cultivar we think it is and grow it next to the one in question. I would think we could do the same with hostas? But with hostas I guess you would have to have the same age division. But divide the existing one, and put it right next to the one you think it is? Maybe identifying hostas is harder than irises, but it seems it would work.
