"Hardy" means "resistant to cold."

It could be thrips; if so, you see very tiny elongated insects scurrying when you separate the petals. They are barely visible.

Or it could be the effect of botrytis fungus after rain in mild weather. It causes the petals to rot in spots or entirely, sometimes with pink spotting.

Could you show us a picture of one on photobucket?
I buy an insecticidal soap spray which has helped me spot spray problem areas like that and still not poison the good bugs and birds.

sam0738, this is one of the Heirloom Roses.

The roses to the left and right of the dying one are not well either.

That looks like botrytis.

A tebuconazole product can treat it.

Yes , Ignatz I would agree with what the rose experts say about it being more toward disease rather than insect. "It makes sense" Fungus because of the rain we both have been having. I have learned so much on this Forum. Right now I have Pruned and thinned out the branches and leaves that collide on my rose de rescht . It got black spot and gave to its neighbors. I have Two other roses that I purchased this year that got powdery mildew. I am here between Saratoga and Lake George. Where Are you?
