Geranium Rozanne (Geranium 'Gerwat' Rozanne)

Geranium Rozanne (Geranium 'Gerwat' Rozanne) is a vigorous, long-flowering hardy cranesbill producing large violet-blue blooms with pale centres over a low, spreading mound of deeply cut green foliage. Ideal for front-of-border ground cover and weaving through mixed plantings or under shrubs and roses, it thrives in moderately fertile, well-drained soil in full sun or light shade. Fully hardy in Ireland, it typically reaches 30–60 cm in height with a spread of around 60–90 cm, and flowers from June to September, providing reliable colour and nectar for visiting pollinators.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.
