Mini roses are tricky sometimes. I thought yours looked more like a fungus but sometimes it's hard to tell with pictures. It's really hard to tell if they will come back or not. All you can do is cross your fingers. They may not show any sign of life till next year.
My bee balm is open now. It has some rust on it but still looks neat. It's right up against the gazebo so we won't be sitting out there for a while. Bees really do like bee balm. Go figure.
