Geranium 'Gerwat' Overview

Geranium 'Rozanne' is a vigorous, spreading, perennial cultivar that produces dense, lobed leaves and attractive blooms. The flowers measure around 5cm across; they are violet-blue in colour with white centres. They contrast attractively against the light green foliage. Very popular with gardeners because of its long flowering period (from early summer to early autumn) and its dense, neat foliage and stunning flowers, it likes some moisture but is tolerant of most well-drained soils. It prefers a sunny spot but can tolerate some shade. Suitable for many garden situations, it is most often seen in cottage-style gardens, mixed flower borders, underplanting roses or shrubs, and it is a good addition to a gravel garden. This cultivar has earned a Royal Horticultural Society (RHS) Award of Garden Merit. It is also part of the RHS “Plants for Pollinators” initiative that showcases plants which support pollinator populations by providing ample amounts of nectar and/or pollen. A great choice for encouraging pollinating insect wildlife into your garden! Commonly known by the names Cranesbill 'Rozanne' or Geranium 'Gerwat', amongst others, Geranium 'Rozanne' was shortlisted for the Chelsea Plant of the Centenary for the decade 1993-2002, and it was the winner of the public vote. It is also protected under intellectual property laws by Plant Breeders' Rights which provide the breeder of new plants exclusive control over the plant material for a set amount of time.
