I would suggest you ask about Eden in the roses forum. There are a couple of NC gardeners that grow Eden. It's a very popular rose.

Pierre de Ronsard was renamed "Eden Rose '88" in USA , and is now commonly known under this name . There is also a rose called Eden Rose , which is a hybrid tea and completley different from PdR . Winter hardiness is not a problem in your climate and it also does well in hot weather . Henrik

Like Ashke, mine has done extremely well, but it was a weel grown, well cared for plant to start with. It has borne heaps of gorgeous flowers, with a bit of balling occasionally, that I can easily forgive. My only problem with it is that I have just realised that it will not clime like Gloire de Dijon, Crepuscule, and Sombrieul, which share the arbour. I may have to move it in winter. I hope it continues to do as well after moving. It grows in an area where the soil is heavy clay and moist most of the year without watering. (Over the septic drainiage bed) I have planted another one to grow up the almond tree. It is already growing and blooming - planted 2 weeks ago. Both get plenty of sun.

I'll concentrate on Q 2: At my previous residence in Sydney I had an archway and planted 2 New Dawn roses to cover it and to weave through the vines 2 Jackmanii hybrid clematis, both Danial Deronda. I bought a book on growing clematis before I ventured and followed the planting and feeding guide: I planted them deep in the holes, about 18 inchs from the rose hole, and beneath each hole I placed a goodly dollop of blood and bone along with a about 10 percent sulphate of potash separated from the plants by a layer of soil. I Kept them watered, nursed them along and after about 3 month both plants got hit with the 'Wilt', clematis wilt! The plants collapsed overnight - you need to check the clematis each morning for collapse and as soon as you see it cut the plant off at ground level as close as you can to just above the lowest growing node. I had one clematis for each rose. I managed to save one and from then on the wilt never affected it again, seems it was immune, even a suckering offshoot which I gave to a friend was immune. Eventually mine grew nicely as long as I fed it regularly, kept its roots cool (I placed a few bricks over the root zone) and ensured it was well watered and it produced these magnificent big bluey-purple flowers. Unfortunately my book on the subject seems to have vanished. The New Dawns put on a beautiful show every spring and had a delicious perfume. I planted the roses one each side of the arch and after one season they had covered it over. Pruning, though, proved a bit difficult and now I'm concentrating on roses for a similar purpose that I don't have to prune - I'm putting in crepusule and I already have in Iceberg climbing to grow up a lattice and the red, Dublin Bay. These three roses will flower from spring into autumn, are not overly thorny, have a nice background green for their foliage are to some degree disease resistant, and mostly have a lovely fragrance, except for maybe iceberg. And pruning should be minimum.
