I have seen Qi Hua Lu Shuang going under several names including Hello Sunshine, Bowl of Beauty and Stunner.
Qi Hua Lu Shuang is one of the many casualties of the rush on Chinese and Japanese peonies of the late XIX century/early XX century I often speak about. Differently from other Chinese herbaceous peonies whose origins (and often original stock) were lost during the turmoil China went through, it remained relatively popular in China and you can still get the original Chinese stock, like I did.
The big problem with Qi Hua Lu Shuang is flower color is never exactly the same on two consecutive years, which often leads people to think the various names are actually slightly different mutants while they are actually just one of the plant's defining characters. Since mine should be mature or nearly so (3 years division plus 8 years in the ground) I am really curious to see if colors will stabilize with age.
