I'm totally surprised that this shows up in a Louisiana newspaper. I always associated spiny rose galls with much colder rose gardens mostly because it's the only place I've seen the galls on roses were in climates colder than mine.
It was only four years ago that spiny galls showed up on my R. eglanteria. I still wonder where the next closest infected roses are.
Has anyone else south of the Mason Dixon line had spiny or non-spiny rose galls?
