I am sure a few people have been growing these forms I have released over the years. I am looking to see how much cold they are taking and in what areas they are growing. I have had them all survive -5 big dipper is always mulched for me but pink china and black pearl have both survived -5 with no mulching. I have had reports of Pink china in Ohio and Michigan. As well as big dipper surviving in Ohio. I would like to hear more about the results of these plants in cold zones. What have been your experiences?
I have seen some struggle and die while others have become weeds. It seems that situation will be key much like Musa basjoo for these to do well. Anyone have photos?
