You brought up a very interesting point, Frank. I think that you are right in your observation about the tissue culture plants and the divisions of a peony plant. I bought a bareroot of Cora Louise at Lowe's in 2013 and planted it that spring. I am sure this bareroot plant is from tissue culture as I did not see any division marks. It looked like a whole root from a small plant. Also the company that sells it to Lowes is involved with growing plants from tissue culture. The plant grew really well that summer with 4 stems. I thought for sure that I would get flowers in 2014. Spring 2014 came and this time there were 10 stems! As they grew, there were no flower buds formed. Otherwise the bush was extremely healthy. Anyway, I hope that I will get at least a flower this year. I will watch this plant to see what happens.
