ADR rose

An ADR rose is a winner in the German ADR rose trial (Allgemeine Deutsche Rosenneuheitenprüfung). No chemical pesticides have been allowed since 1997 and breeders often describe the trial as among the most challenging in the world. The trial is set up by a working group that includes the Bund deutscher Baumschulen (German nurseries association), rose breeders, and eleven independent trial stations in Germany. The trial results are analyzed by the Bundessortenamt (Federal Office of Plant Varieties).
