Is this rose rosette?

Asked July 12, 2020, 2:07 PM EDT

Hi, I live in Portland OR and recently noticed some very abnormally red growth on our rose bushes. Is this rose rosette and, if so, what is the best course of action? I also noticed that my neighbor has new rose bushes that might be multiflora - is this problematic?

Multnomah County Oregon

Thank you for the images.

No, this is not rose rosette.

It is vigorous new spring growth which will eventually turn normal green color.
