Thank you for your assessment of the various peony vendors with pics of the roots. I agree that tree peony garden offers the biggest tree peony roots for a very reasonable price. If I have more planting space next year, I would definitely like to order some tree peonies from them. There was a member on Gardenweb who purchased tree peonies from Tree Peony Garden last year and the trees had several blooms this past spring. That is impressive given the fact that many places that sell tree peonies say not to expect flowers the first year. I think that they have raised the bar on tree peony roots quality.
