This is a classic. Dorothy Perkins would have to be one of the best known of all scrambling, rambling roses. This one has been allowed to grow as it will over a tall frame. I've never cut it back, just allowed it its head - something which will have to be remedied soon as it is getting just a tad out of control. It's near a pump which waters our garden, so control is necessary because we don't really enjoy being scratched to pieces when repairs are need.
However, that mistake was ours and not the roses. Just at the moment it is a glorious picture of varying shades of pink.
Truly a lovely rose, but only if you have oodles of space.
