I have had this plant in my Southern California garden for several years. It is lovely in full spring bloom. It is growing in a somewhat shaded location in clay soil near the coast. Under my garden conditions this rose has been bullet-proof for me. It has never been sprayed and the foliage is always healthy. It is neither short or compact in my garden but I have pruned it into obedience. It behaves like a Hybrid Musk for me throwing out long flexible canes which I have to prune hard to fit into the available space. Just this week, I noticed small amounts of wilted and burnt looking foliage on several canes which I removed completely. It looked like the beginning of fire blight. I have never had fire blight on my roses but have seen it on pyracantha. I hope that this will be the end. I'm just not certain what is causing the damage to the canes and foliage right now.
