This fine hybrid musk is a tall grower to about 7', though the canes will arch over. It is best trained on a support because the canes can flop over if it rains when it's in full bloom. It blooms with good continuity. The medium sized crimson blooms occur in big clusters and produce lots of hips in fall. Some say it has a strong scent and is disease free. To me it has little scent and gets some blackspot, but it's still a welcome addition to my garden with it's lovely clear color. It was named after an Indian Empress. Bred by Pemberton in 1923. Hardy from zone 5.
