I did and I got an answer back after I had posted here. They say the plants have been hardy for them in their zone 5 garden except they aren't sure about Dr.C.Stump. I have a feeling the price tag for these seeds will end up going way past what my wallet will allow anyway. One can dream and I think I'm spending too much time in LA LA land anyway. We usually do have good snow cover in my garden but the last two winters have been sadly lacking! I think that I should stick to proven hardy plants and seeds. Thanks BB.
