This event takes place every year and coincides with the when roses first bloom. The contest features a prestigious international jury and showcases the finest new creations by rose cultivators from all over the world.
All the varieties in the contest have been created by rose growers who have crossed existing varieties. The flowers are all brand new creations and have never been sold commercially. To obtain a new rose variety, cultivators need to spend around ten years working on it before being able to present it for competition and marketing it.
