According to the web site of Les Roses Anciennes Andre Eve (https://www.roses-anciennes-eve.com/grimpants/538-ROSIER-RED-PARFUMR-everepra-RN.html), the official epithet of this cultivar is 'Everepra' (RED PARFUM is a registered trademark, never to be confused with a cultivar epithet or displayed in single quotes, according to the International Code of Nomenclature for Cultivated Plants.) I do wonder a little about the spelling of the name (shouldn't it have been 'Everepar'?), but that is what they are going with. A catalog description of the cultivar is also offered, which might be helpful for the rather empty References section!
