We had one of those new fangled Prairie style gardens. We dug it out on the grounds that if you provide a suitable growing condition for Ornamental grasses then couch and creeping fescue and other unwanteds will also like it and boy did they.
Zephirin Drouhin might be thornless, but here it is leafless from mid August onwards because of blackspot which causes the leaves to fall off.
We have Shropshire Lad, and it is definitely as thorny as all the other roses. And it has blackspot, mildew, greenfly and mushy flowers after the over night rain.
