Begonia Fleuroselect 2025

Objectives and purpose of the trial

The purpose of this trial is to assess Begonia cultivars grown in open ground as well as pots. The trial at RHS Hyde Hall, Essex, will compare new introductions against established cultivars to see how they perform. Those that perform best and meet the judging criteria will be awarded the RHS Award of Garden Merit (AGM). The RHS has teamed up with Fleuroselect, an international organisation for ornamental plants, to bring the Begonia Fleuroselect trial.
