Hedychium 2024–2027

Objectives and purpose of the trial

The RHS has never trialled Hedychium (a genus of flowering plants in the ginger family) and a large number of cultivars have appeared on the market in the last decade. Considered far more tender than many of the cultivars seem to be, the RHS Trials team will assess the hardiness of Hedychium at RHS Partner Gardens East Ruston Old Vicarage Garden in Norfolk and Floors Castle Walled Garden in Scotland. Those that perform best will be awarded the RHS Award of Garden Merit (AGM).
