For a very long time, it clearly wasn't. Both roses planted in this slot between the boulders languished and nearly died. Opal Brunner is supposed to be a Climbing Floribunda, with something of a Hybrid Musk look to it. In my garden it wasn't climbing, it wasn't florabunda-ing, it was pretty much on its way to dying. But it didn't quite make it there, which suggests that it is a Rose Which Can Survive Severe Neglect. My garden tends to select for these. Opal Brunner was a plant which never died, but it didn't exactly love life.
