What a great thread
I will rate only my tree peonies, because I have no fancy herbaceous peonies, just common varieties that you could find in any garden.
Best Overall Performer and Most Consistent Bloomer: Hoki
In my garden since 2004, and it has never skipped a blooming season. It has to compete with other roots in this harsh climate. I also rarely feed it, but it blooms every year
Most Mysterious: Snow Lotus
This one is close to the wild species, and I cannot help but wonder how and why nature created such a beautiful flower. It has hypnotic effect on me
Best Photo: The Guardian of the Monastery
Absolutely the most photogenic one. This one in the picture got sick two years ago and might not survive
but I planted two new ones last fall
I simply cannot imagine my life without the Guardian
