This is a low-growing hybrid, originally bred at Cambridge University. Plants form a low, spreading mat of fragrant dark green leaves, bearing clusters of bright magenta-pink flowers. The very long blooming period sets this apart from others, and makes it especially useful as a low groundcover or edging plant. Also worth considering in tubs or mixed containers. Fairly drought tolerant, once established. Easily divided in spring or early fall. Evergreen.
Raised at Cambridge University Botanic Garden in 1974, name first published in 1989 by Axletree Nursery (now defunct).
Several new hybrids where also named by Dr Yeo and one of the best and most popular is G. x cantabrigiense, a hybrid between G. macrorrhizum and G. dalmaticum. It makes an excellent groundcover in both sun and shade bearing light green foliage and pink to white flowers.
Most plants that are sold simply as “Geranium x cantabrigiense” seem to be this form.
