I first saw this rose in a wooded situation at Wisley and it was doing fine. This specimen is out in the open in the new Bowes Lyons Rose Garden, again at Wisley though it is a different beast altogether. While it can happily manage a shady spot, it clearly loves an open sky. A very early-flowering rose – out with Canary Bird and Lady Banks’ rose (Rosa Banksiae) – with flowers arranged along the length of the arching branches, set off by small ferny leaves, it is a great sight.
