Just this week I found several galls on one rose and spent some time
researching online. I believe this is a bacterial gall, not a wasp. The plant
is infected from the bacteria which comes from the ground. General consensus
seems to be get rid of the plant right away, disinfect all pruning tools,
replace the soil and don't replant for at least five years. Wow!

Here are some links I found:

I haven't removed the rose yet. It stands alone, several feet from any other
roses, and if removed I wouldn't replant in that location anyway. So far I
haven't noticed anything unusual about the performance execpt for some dieback
of the smaller growth. And that isn't very unusual for this large climber.
There are at least 6-8 galls I've found so far, including the crown. Cutting
away part isn't an option. So for now, I'll let it stand and watch it.

Wasn't it Cass who recently said she had POed the rose gods. I don't think
she's the only one!
