Gardeners' Notes:

I bought this peony from a discount bin. The first year it survived, the second year it thrived, and the third year rewarded me with a lush profusion of blooms. I have a couple of different clumps now. One is in good loam, and the other is in a more clay situation that gets quite dry in the summer. We also have very wet winters. The clumps don't appear to suffer from rot when it's wet, and they hang tough through the dry season. Both clumps are in heavily-planted beds and the crowding doesn't seem to bother them. A very nice, sturdy peony for our area in the Pacific Northwest.

Side note: In 2009 we got quite a few feet of snow that killed several otherwise reliable perennials. The peonies bloomed afterward just as nicely as they have all the other years.

I first planted four of these four years ago. They are growing in various degrees of part shade. They grow well and bloom profusely. Each year I have added 2 more. In part shade, they require staking. Last year toward the end of the summer, they were attacked by powdery mildew, which gave the foliage a silvery color, which I actually enjoyed.

Just got one of these for my birthday, says it grows 30", blooms in spring, likes full sun and perennializes easy.

Ours need to be planted in April- June (zones 5-7) and will bloom in spring. I am assuming it will bloom the following spring and not the same spring it is planted..?

I am thinking it would go nicely with our tiger lily perhaps in a large pot with a mixture of other bulbs.

A nice raspberry red double peony. One cultivar that I grow and cut for dried arrangements. More of a medium size blossom.
