One of our members (Michael = gardenexpert) has a nursery and sells tree peonies.
I've been working on a Catalog on CD for their product range.
Michael sells Camellias. I broke off from the Catalog on CD project when you sent me the photos of the Camellias at Leuven Botanical Garden, to develop the Web Page Generation feature in IG Pro.
Back to the Catalog soon, and members can have a copy of the finished article.
The Imberhorne web site was revamped this year to include their new range of these beauties.

On their web site, heres a page which may be of interest, Cultivation of Tree Peonies
http://treepeoniesonline.co.uk/index.php?main_page=page&id=8&chapter=8Ive never seen one before, so its interesting to read your description, and in particular, to see a photo of a whole plant.
Has it grown much since planting? Any more blooms?
