Geranium ‘St Ola’ is a delicate, pale-flowered version of one of our favourite species, Geranium x cantabrigiense. It is an improved form of Geranium ‘Biokova’, its flowers remaining white for longer before ageing to pink. Developed at Cambridge University Botanic Gardens in the 1970s, Geranium x cantabrigiense is a sterile hybrid which forms a slowly spreading, low-growing carpet of glossy foliage, turning brilliant shades of scarlet during autumn and winter. The flowers have pink veining, long anthers, and are produced in abundance from late spring to midsummer. Following this initial flowering period, ‘St Ola’ will often continue to bloom sporadically well into autumn. ‘St Ola’ is an attractive groundcover plant, perfect for forming a lush, colourful mat beneath trees and shrubs, or lining a path or border edge. In milder winters it can remain evergreen, though more commonly is semi-evergreen. Maintenance is wonderfully straightforward; simply remove any tatty leaves in spring. For best results grow in full sun to partial shade, in moderately fertile, moist, well-draining soil. H: 20cm S: 50cm. Hardy to between -15 C and -20 C.
