I saw your post and was hoping you were talking about Henrii clematis. It is my favorite one too. Drop dead reliable and gorgeous for me in two cold climate gardens, northern Minnesota and Alaska. It is interesting that it does so well over such a diverse geographical area. I am moving (again) to a new home further north. I will be keeping my eyes open for a perfect spot for another Henrii clematis to plant next year. Right now I have my patio loaded with potted up lilies and assorted perennials to bring to my new home. There is an no longer used terraced vegetable garden at the new place which I will use as a temporary home for my plants as I get a good feel for the property. To many plans, to many plants and way to little summer days to get everything done this year.
