Harlekin
Of all the roses that have this coloration, I think this one is the best.  It is a climber but is sturdy enough to grow without support.  The blooms are a good size, and are a beautiful shape with a strong fragrance.  Rebloom is  good and most of the time the plant is  blackspot resistant.  It can get some blackspot at the end of the summer.  It was bred by Kordes in 1986, hardy from zone 4.  It is also known as Kiss of Desire.
