I have added the 20 to the name, Jay-Jay. But I am unable to alter the surname from Van de Pas to van de Pas. I have tried, but I think the database automatically capitalises surnames.
it even seems to be "van de Pasch". As I wrote in the other thread, on which Jedmar reacted... and in which I added a link: "I found the probable correct name at this place: https://www.wijlimburg.nl/nieuws-overzicht/limburgse-kwekers-nemen-nieuwe-roos-in-productie/ Harry van de Pasch. He created more than ten roses of which Rosa Prinses Margriet, Rosa Hertogin van Limburg en Rosa Limburgs Land are some."
