RHS Chelsea Flower Show Plant of the Centenary

An award-winning perennial celebrated for its long blooming period and stunning lavender-blue flowers with a white eye and purple veining.

Thriving in full sun to partial shade and well-drained soil, Geranium 'Rozanne' ties garden designs together with its cohesive flow of colour and form. It softens edges, fills gaps, and adds lasting interest alongside shrubs

Flowering from early summer to mid-autumn, this fabulous cranesbill, judged by the RHS as the best plant introduced at the Chelsea Flower Show over the previous century, forms a spreading, mounding habit with deep green, lobed foliage that takes on reddish tints in autumn.

Fully hardy and easy to grow, it’s also wildlife-friendly, attracting bees and butterflies, making it a valuable addition to borders, rock gardens, containers, or as ground cover.

How to care for Geranium Rozanne ('Gerwat') (PBR):

Plant in partial to full shade with well-drained, humus-rich soil, either in the ground or a large pot using ericaceous compost. Space plants to allow for spreading and water well after planting, keeping the soil moist during dry spells.

Apply a 5-7cm (2-3in) mulch of leaf mould or compost in spring to conserve moisture and suppress weeds. Pruning is minimal—cut back old, damaged, or dead foliage in late winter or early spring to make way for new growth and reveal flowers. Fertilise lightly with a balanced or ericaceous feed in spring if growth requires bolstering.
