Research work into the taxonomy of hardy geraniums undertaken Dr Peter Yeo during his long tenure as Garden Taxonomist has provided a wealth of new hybrids and selections with Cambridge connections. One of the best and most popular is Geranium x cantabrigiensis.
This hybrid between G. macrorrhizum and G. dalmaticum has arisen spontaneously on a number of occasions, but was produced here under experimental conditions in 1974 and then selected and named by Yeo.
This vigorous plant with light green aromatic foliage and pinkish purple flowers makes an excellent ground cover, rock garden or front of border plant. Growing to a height of up to 30cms it flowers from June to July and copes well in sunny or shady garden situations. It can be seen gracing many areas of the Garden, including around Brookside, in the long border along Lynch Walk, and in the Geranium Beds just east of the Limestone Rock Garden.
