It is amazing as many cultivar that have already come to be that there are such beautiful ones still being brought forward. I think that is one thing that I find so fascinating about DL. The gene pool seems endless. Those are such beautiful blooms and several Hybridizers are working towards rust resistant varieties and all the new forms.
That being said I can envision some of the above being taken to other forms with the patterns in them.
For those that have not seen Doris's property you are in for a spectacular treat this year as it is remarkable. Can't wait to see it again myself as it is everchanging. She has the most beautiful Lady Banks ( I believe that is the name>) rose you have ever seen.
