According to the David Austin Site:

There are several dark red English Roses, but this is a lighter, brighter crimson, which is slow to fade, so it has long been a valuable addition to our collection. It is related to ‘Mary Rose’ and has many of that rose’s good garden qualities. The petals are loosely arranged to form beautiful, large, slightly cupped blooms that open wide and flat. Flowers are produced with remarkable continuity. There is little scent until the flower ages, when it develops a charming Old Rose fragrance.
