Moss.  

Rose-pink or vermilion, white veining, white edges.  Strong fragrance.  Very large, very double bloom form.  Occasional repeat later in the season.  

USDA zone 6b through 9b (default).  

There seems to be more than one variety of 'Mme. Moreau' in commerce. One striped, one white-edged, and perhaps a slightly mossed violet-lavender version.
'Mme Moreau' at Sangerhausen seems to be mislabeled (see References)
