Thank you for mentioning this nursery, Steve. I had never heard of it before. I've spent a few hours reading their website pages and I have to say they have changed my views on roses.
One argument they make is about buying non-remontant roses. They point out that we don't think twice about planting a lilac that only blooms once a year, so why expect a rose to do more? Today i saw a lilac bush in full bloom. it was an old variety, a huge old shrub, and it was fully blooming. I think our cool wet weather last week fooled some plants into thinking it is spring. Of course i was gone and missed the cool rain.
Anyway, I'm going through their extensive lists and looking more at the Damasks, Centifolias, Bourbons and maybe a few chinas. I love the older forms, which is why I love the Austin roses so much. "Reproduction" roses, in their words. Reproduction with improvements.
Most of the Chinas are listed as zone 7 and warmer. Has anyone had good experience with them in zone 6?
