Aubrieta, Arabis and Aurinia trial 2024–2026

Objectives and purpose of the trial

The purpose of this trial is to compare, record and display the merits of new and established Aubrieta, Arabis and Aurinia (Brassicaceae family) cultivars. These popular garden alpines are easy to cultivate, and many are widely available at garden centres and nurseries. Since these three genera were last trialled in 2007, new cultivars are now available. This trial will assess the availability of these plants and test standard old cultivars against more modern introductions at RHS Hyde Hall, Essex. Those that perform best will be awarded the RHS Award of Garden Merit (AGM).
