The Gold Standard Trials are the result of a joint initiative between professional rose breeders represented by BARB (British Association of Rose Breeders).
Unlike some other rose trials, breeders pay a fee for each rose variety submitted to the trials, managed by RNRS at their St. Albans headquarters. Based on cumulative information from invited independent judges throughout the two year period of the trial, the Gold Standard is awarded to worthy varieties. Health, floriferousness, scent and commercial appeal are all considered key factors.
