Updated with some more info I received from Aleksej.
Freezing cold outside and snow on the ground. In our unheated plastic hoophouses, the first peonies are peeking through the soil. Only the ones treated with Ga3 as yet, the other ones will surely follow suit. Half of the rows received this treatment. Two left rows are Old Faithful, four right ones The Fawn.

liked this1 CommentThe American Peony Society just sent me their latest Bulletin. Lately they have done a lot of effort to make membership more attractive than ever before. Their website did receive a full revamp and for the future all past Bulletins wil become available online for members. That’s quite a treasure when you’re really into peonies.

Hello, if anyone knows where in Europe I can buy Rose Crystal peonies, I would be grateful for the information

Had to look that one up as it was unknown to me. Seems to be a lactiflora x macrophylla (probably tomentosa) hybrid by Saunders. I can’t really think of an easy source for that one in Europe. There are some specialty peony nurseries in Europe that list several Saunders hybrids. Ruud Warmerdam at http://www.paeoniapassion.com or Daniel Giessler and Anita…Read More

Didn’t expect it anymore, but apparently the third volume from Hong De-Yuan’s books on peonies is in print. The species classification is about to have an update.

Hum, I wonder what they are trying to contend here, when they appear to show two different P.Brownii, and two different P.Californica ? It seems like they do this with several other of the species as well. Are they just saying that they looked at several different samples, or are they saying that they found distinct subspecies ?

@bobjohnson I think they simply took two plants from different locations. Even within species there are small differences, both between different locations and probably, though smaller, also between plants in the same population. If you would stand before a population of such a species and could take home whatever you’d like, I guess we’d all go…Read More

We have Brownii growing locally in the forests here, but despite it living at a higher altitude than my house, it blooms very early – much before the herbaceous hybrids at my home bloom. If one wanted to try hybridizing it, you’d pretty much need to have it growing on your own property I think, so you could keep track of the exact time that the…Read More

Outside, newly planted ones. If storage of the roots is too cold and early Winter too hot, this may occur. We’ll see how they handle this cold spell.
