Hi LucindaStreets Welcome!

That is Rose Gall. I see this was on the rose forum, too. Hopefully
someone who had experience with this will help you.

I think it is diplolepis mayri causing the gall. It is an insect. But I am not familiar with it. I have no idea what to do. I hope someone here knows what to do. I am sorry I can not be more helpful.

May you be blessed with answers and success.

Caused by spiny leaf gall wasp, Diplolepis polita or one of the other Diplolepis species that affects roses:

@LucindaStreets

I found this article written by a master rosarian in the Rocky Mountain Denver Rose Society. Hopefully close to your area. Maybe this would help you with your diplolepis.

Sharon Rose's article is about cane galls, I think the spiny ones in the ID picture may be leaf galls caused by a different species of Diplolepis. There are a surprising number of different species causing mossy or spiny galls on various different parts of roses. According to one research article there are thirteen different Diplolepis species affecting different rose species and plant parts in the Canadian Prairie provinces alone.

Well I think we can agree that it is:

1) Rose Gall
2) Diplolepis
3) and the rose is not going to die today or have to be ripped out such as with rose rosette disease

Thumbs up So it is a good day! I only provided the article (did not write it) to show that it was not life threatening to the rose, whether the leaves or cane are affected...And those little insects can be fascinating based on the ending of the article.

Edited to say (whether the leaves or cane are affected)

May everyone be blessed with a good day!
