You are right, Liz! We will never know if the plants that Select Plus started out with were the original field grown plants divided from the original itoh plants or they started out with tissue culture plants. If the seller does not disclose its source, we just don't know. I know my Bartzella that I purchased from Solaris Farms is an original root stock because the seller said he does not propagate from TC. The same goes for my Pastel Splendor, Hillary, and Singin in the Rain which I got from Adelman peonies. And I don't think they sell TC or propagated from TC plants.
