Aruncus trial 2024–2026

Objectives and purpose of the trial

The RHS has not trialled Aruncus (a genus of clump-forming plants in the Rosaceae family) before, so this is an opportunity to see how the different species and cultivars perform side by side at Royal Botanic Garden Edinburgh (RBGE). Those that perform best will be awarded the RHS Award of Garden Merit (AGM).
