Origin and Breeding
Controlled pollination: 'KORjupvio' was the resultant seedling from a cross between an unnamed seed parent with another unnamed seedling (MACgenev x unnamed seedling) in May 2008 at the breeding facility of W. Kordes Sohne in Sparrieshoop, Germany. The seedling was selected in May 2009 and was budded onto Rosa canina planted in the open field. Follow up selections took place in 2010 and 2011and was commercially introduced into Europe in September 2018. All breeding and selection processes were conducted by or under the supervision of Wilhelm-Alexander Kordes. Breeder: Wilhelm-Alexander Kordes, W. Kordes' Sohne Rosenschulen GmbH & Co KG, Offenseth-Sparrieshoop, Germany.

This one is interesting. That likely pollen parent has been used before, as well as the codename Vio, which is usually for 'Violina'. Maybe the unspecified "seedling" :P

Edit: I think it is possibly Violet Parfume x (Caramel Fairy Tale x New Zealand). I know Kordes also uses Violina and Claude Brasseur for their larger violet type roses in recent years, but I think its Violet Parfume in this case. We'll never know, of course ;]
