About

Geranium x oxonianum f. thurstonianum 'Sue Cox' is a clump- and mat-forming herbaceous perennial in the Geraniaceae, producing low, trailing growth with dissected, patterned foliage. It favours full sun and neutral, moist but well-drained soils and is rated H7 (fully hardy) in the UK. Flowering runs June to September, with small blooms carried on short stems above the carpet of leaves. The plant suits planted edges, rockery pockets and mixed borders where a low, spreading habit is wanted.

In the garden

Geranium x oxonianum f. thurstonianum 'Sue Cox' is a herbaceous perennial in the Geraniaceae with a clump-forming, mat-forming and trailing habit. It presents dissected, patterned leaves that are light green with silvery tones, and it forms a close carpet of growth rather than an upright mound. The cultivar belongs to the Geranium group of cranesbills commonly used as ground cover and edging plants. Plant it in full sun on a south-, west- or east-facing site where it will receive good light without constant exposure; a sheltered position suits its trailing habit. It tolerates sandy, loamy or clay soils provided they are neutral in pH and remain moist but well drained. In the UK it is fully hardy (H7), so winter protection is not usually required on typical garden sites. Use 'Sue Cox' at the front of borders, in cottage or rock gardens, under open shrubs or in containers where a low, spreading carpet is wanted. Flowering occurs from June to September, with successive displays of blooms sitting neatly above the silvery, dissected foliage that defines the plant's ground cover effect.
