Geranium Rozanne ='Gerwat'

Common name: Hardy Geranium Rozanne

Description: This award-winning hardy geranium is renowned for its exceptionally long flowering period, producing masses of violet-blue flowers with white centres from late spring through to the first frosts. The deeply divided, semi-evergreen foliage forms a spreading mound that provides excellent ground cover. Each five-petalled flower measures approximately 5cm across and features delicate purple veining. 'Rozanne' is remarkably vigorous and reliable, continuing to produce fresh blooms throughout summer and autumn when many other perennials have finished flowering. The foliage often takes on attractive burgundy tints in autumn.
