An oldie but a goodie, Geranium 'Rozanne' is a cottage garden favourite for her attractive, deeply lobed, foliage, topped with masses of violet-blue flowers with a distinctive white centre and striking dark blue veining. 'Rozanne' is not only a vigorous and robust selection, but one of the longest flowering hardy geraniums, flowering from late spring right through to late autumn in mild areas. 'Rozanne' is a magnet for butterflies, bees and other pollinating insects and a wonderful filler and weed suppressor in garden borders. Plant in well drained, moderately fertile, soil, in sun to part shade. Trim as required over summer to maintain appearances and hard back in late autumn to early winter to promote fresh new spring growth. Evergreen.
