I asked a question about forever roses the other day. Part of your response was that you were not sure what I meant by forever roses. I was surprised that you had not heard of forever roses. They have been on the market for many years and are becoming more popular every year. They come in red and pink and bloom all summer. They do not have any fragrance. They do get many flowers. Unfortunately the deer like to eat them. I have to spray them all summer with Liquid Fence. Thank you for your response.
We think from your description you might mean the shrub rose called Knock Out roses?

Since this publication in 2011, there has been a serious and unfortunately as yet, untreatable disease that roses in our area can get called Rose Rosette disease to keep an eye out for. http://www.extension.umd.edu/hgic/rose-rosette-shrub
