Hello,
I bought Lavender Lassie rose bush 4-5 years ago from a reputable nursery. It was doing ok for a few years (was true to the name and such). Last year it didn't bloom almost at all but grew like crazy. This year it decided to bloom and it is covered in buds but really weird buds. They just started to open and they look nothing like Lavender Lassie I remember: a mass of small penny size single flower in clusters. What happened to it? Should I get rid of it?
