Is Rockii first flowering tree peony?
I bought a Rockii tree peony in a small pot last year. After that I transplanted it into a 50cm diameter container. This year it shows four flower buds, but they stop growing, since they reach the size of peas and beans. I wonder they'll get bigger and bloom? Compare to my 'High Noon' that has the Walnut size buds. It seems to be blooming before Rockii.
