Karen, I did not ask that particular question but what Therese wrote to me about Magical Mystery Tour (I also bought this one): "I am not sure if the Magical Mystery Tour is from tissue culture, as I purchased my stock later - however, it divides well; not hard to divide like the one tissue culture plant I have (Shining Light). I try to stay away from tissue culture rootstock - it is too difficult to divide and long term results are unknown."
I always ask before buying what propagation method they use in a nursery. I know that in Solaris Farm, Hidden Springs Farm, Fina Gardens, Swenson Gardens and American Meadows they use root division.
