The first two stages of the trial of hardy geraniums included plants suitable for general border use. However, stage 3 of the trial features plants with more specialised cultivation requirements, including those suitable for rock gardens. There were far fewer hybrids among the Stage 3 plants than in the previous stages and most were selections of Geranium macrorrhizum, G. maculatum, G. nodosum, G. phaeum and G. sylvaticum. Many of the plants in the Rock Trial were selections of G. subcaulescens or hybrids of that species included in G. lindavicum and Cinereum Group. The bulletin contains details of 12 hardy geraniums awarded an AGM and eight that were reconfirmed.
