Primula, Sikkimenses and Proliferae Sections trial 2025–2027

Objectives and purpose of the trial

The focus of this Primula trial is on cultivars specifically from the Sikkimenses and Proliferae Sections. All existing AGMs were selected through RHS Expert Group review rather than through planted trials. The RHS Trials team aims to assess new and established cultivars and performance for garden use at RHS Partner Garden Holehird Gardens in Windermere, and those that perform best will be awarded the RHS Award of Garden Merit (AGM).
