In the garden

Geranium 'Rozanne' is a cultivated member of the Geranium genus (family Geraniaceae) with a spreading, mat-forming habit and dissected, light green leaves showing silvery patterning. Its habit ranges from clump-forming to prostrate and trailing, so it fills space at ground level while maintaining open cover rather than forming a high mound. The flowering season runs June to September, giving months of colour through the main UK summer. Plant in full sun to partial shade; the cultivar tolerates all garden aspects (north, south, east and west) and will perform in both exposed and sheltered sites. Soil can be chalk, clay, loam or sand and any pH from acid to alkaline to neutral, provided it is moist but well-drained rather than waterlogged. Hardiness is H4, which translates as average hardy for UK gardens and means it will survive typical winters in most areas without special protection. Use Geranium 'Rozanne' as a ground cover in borders, to soften the edges of rock gardens, between stepping stones or beneath taller shrubs in woodland-style plantings. Its trailing stems are particularly effective for spilling over low walls or masking paving joints, where the extended June–September flowering keeps gaps filled across the summer months.
