Geranium Rozanne’s Behavior Through The Year
Perennial Hardy Geranium, Or Cranesbill
Rozanne is a Hardy Geranium, also sometimes known as a Cranesbill. Hardy Geraniums are perennial plants that live for many years. However, they aren’t visible all year round! Perennial Hardy Geraniums appear to wilt and die as the cooler seasons and hard frosts arrive, but actually they’re simply going to sleep for the winter. When the ground warms up again in spring, they re-emerge with fresh new leaves, full of energy to flower again through another summer.
Although they are part of the same Geraniaceae family, Hardy Geraniums are not to be confused with Pelargoniums, which are also commonly known as Geraniums. Pelargoniums are half-hardy plants native to the Mediterranean that cannot survive winter in cooler climates. When the frost sets in on a Pelargonium, it really does die! Pelargonium Geraniums are commonly available in the UK and other cooler regions where they tend to be used like annuals and bedding.
No Expertise Required
Rozanne is a plant that everybody can grow. Her strong constitution and ability to adapt to a wide variety of conditions means there’s very little that can “go wrong”. You really don’t need green fingers to enjoy great looking results when growing Geranium Rozanne.
Water And Temperature
She can deal with both deluge and drought, so you don’t need to stress about over or under-watering. She can take the summer sun and the winter cold – even though she does need to hibernate! – so she’ll happily live with you wherever you are.
When you consider that she first came to life in the changeable temperate climate of an English garden yet also thrives through California’s heat and humidity and Canada’s long cool winters, you can start to picture just how versatile she is!
Rozanne will live life to the full through a wide range of intensities of sunlight and amount of daylight hours. However, natural sunlight is very important to her and she doesn’t enjoy being inside, even in a glass-covered conservatory. Rozanne is most definitely the outdoors type. Just remember that, and she’ll be fine.
Rozanne will look better for an occasional tidy up, but she’s not one of those plants that insists on it to keep flowering. She’s happy enough to be left to her to her own devices. However, if she starts to look a bit scruffy as time goes by you might want to give her a bit of a trim and pick out any unattractive bits. There’s no magic formula – cut away as much or as little you want and don’t panic if you even cut away all the flowers. It’ll all grow back.
Rozanne Is Versatile
As long as she’s outside in natural sunlight, Rozanne can grow in whatever space you choose for her.
Borders And Groundcover
Geranium Rozanne is naturally a perfect border plant, giving the garden a bold splash of blue right through the summer. Because of her dense habit, weeds have a hard job taking root in the same spot. She can spread to fill large spaces, so if you’d rather have gorgeous blue flowers than endless rounds of weeding, Rozanne is the plant for you!
Despite her sizeable nature, Rozanne takes well to being grown in patio containers and even hanging baskets and window boxes, spilling beautiful blue-flowered trailing stems over the sides. Examples of these can be seen at Foggy Bottom in The Bressingham Gardens.
Because of her robust constitution, energetic habit, low maintenance requirements and long flowering period, as well as her decorative beauty of course, Rozanne is perfect for mass plantings. She’s become popular among landscape designers, particularly in Germany. Adrian Bloom’s use of it spilling out of a Norfolk flint well in his 2000 Chelsea Flower Show garden and his famous River of Rozanne at the Bressingham Gardens, since replicated in Germany and the USA, demonstrate more artistic landscape possibilities. And of course, she’s perfect for keeping weeds at bay.
