A name previously used in commerce was 'Aurora'. Cedergren & Co in Råå and Hallandsåsens plant shop in Laholm sold this rose under that name. During in-depth studies on the name 'Aurora', it turned out that the name 'Aurora'/'Aurore' was used for at least ten different sorts in rose literature and in Swedish price lists. Due to the scant published information on the Aurora, none of them could be assigned to the rose found during the inventory.
