Geranium ‘Rozanne’

Family: Geraniaceae

Geranium ‘Rozanne’ (‘Gerwat’) (PBR) was selected as the winner of the RHS Plant of the Centenary, at the RHS Chelsea Flower Show back in May 2013.  What makes this plant so special?  ‘Rozanne’ has a lot to offer.  This hardy geranium produces large (5cm) intense, violet-blue coloured flowers that have white centres and this plant has a longer flowering period than many other geraniums.  This is a fantastic plant to grow for bees, hoverflies, and other pollinating insects, as they are really attracted to Rozanne’s flowers.

Geranium ‘Rozanne’ is a hybrid of Geranium himalayense and Geranium wallichianum ‘Buxton’s Variety’.  This plant appeared as a seedling in Rozanne Waterer’s garden and so it was named after her.  I’ve found that Geranium ‘Rozanne’ will grow happily in sunshine or partial shade, but these plants will truly flourish in a really bright and sunny situation and flower and appear at their best in these circumstances.  ‘Rozanne’ is not a fussy plant and given sunny conditions and any reasonable soil this plant really couldn’t be easier to grow.  Plant in any moist, but well-drained soil.  Avoid very wet soils and waterlogged sites.

Give Geranium ‘Rozanne’ a good haircut in mid summer (or whenever the plant is looking tired and blooming has tailed off) and your plant will produce a lovely new dome of fresh leaves and will soon send up lots of new blooms.  ‘Rozanne’ is an incredibly long-flowering plant.  I often see ‘Rozanne’ listed in catalogues and online where it’s usually described as flowering from June until October; however, I grew this hardy perennial for around ten years in my old garden in Surrey, where my ‘Rozanne’ plants bloomed from the end of March or beginning of April until October, every year.

Geranium ‘Rozanne’ grows up to around 60cm (2ft) tall and spreads to cover an area approximately 80cm (2.6ft) wide.
