This cultivar is listed as triploid in the paper 'Pollen diameter and guard cell length as predictors of ploidy in diverse rose cultivars, species, and breeding lines'
After approx. 8 years I am confident in saying that this is a very good performer, as are many other hybrid musks, in the hot humid deep south, Zone 8b. The blossoms remind one of very large Apple blossoms. Requires a minimum of care and spraying. Will get to 4 feet in diameter and 4 feet high about 2-3 years after planting. Blooms most of the summer, heavily Spring and Fall, lighter in mid summer. Spent Blossoms drop cleanly. A very welcome feature.
