I am trying to figure out if Hakuro Nishiki is a patented plant. I have searched and read a lot of information about it and I am starting to believe that there is no patent on it but thought maybe someone here could tell me for sure. A friend had bought this plant and she read the name (well spelled it) Hakuro Nishiki to me over the phone and I wrote it down but now she can not find the tag. I took cuttings and they have already rooted but I am wanting to make sure I did not do a "NO, NO".

Does anyone know?
