Plant this Geranium now & enjoy blooms all summer!

Some plants don’t flower for long and although they can excite us with their fleeting beauty, the brevity of their blooming often leaves us wanting more.  If you’re looking for a plant with a generous, floriferous nature, and ability to bloom throughout the summer months, let me recommend Geranium ‘Rozanne’ (‘Gerwat’) (PBR).

Geranium ‘Rozanne’ has a lot to offer gardeners. Once ‘Rozanne’ is established, these plants are very tolerant of droughts. This hardy perennial has a long flowering period, and plants don’t require any special care or attention. Rozanne flowers are a magnet for bees, hoverflies, and other pollinating insects.

‘Rozanne’ is a hard-working perennial.  Plant ‘Rozanne’ in your garden now and enjoy her blooms all summer, safe in the knowledge that next year (and in future years) ‘Rozanne’ will return to delight you!  I find that most gardeners possess a particular fondness for blue flowers.  ‘Rozanne’s blooms display the same colour tone but a more vibrant shade of Parma Violet-blue; the flowers’ beauty is further enhanced by their attractive white centres.  This cultivar has larger than average flowers, compared to most hardy geraniums.  Bees, hoverflies, and other pollinating insects are attracted to Rozanne’s blooms; it’s a fantastic plant to grow for insects!

Geranium ‘Rozaanne’ is a fabulous plant to grow for bees; the blooms attract solitary bees, honey bees, and bumble bees.
Geranium ‘Rozanne’ is a hardy perennial that will flower all summer long and die back over winter, before growing up again in springtime, ready to flower again next spring and summer. ‘Rozanne’ is a perennial that will add a floaty, relaxed feel to your garden.

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 was named after her.  I’ve grown Geranium ‘Rozanne’ for around 10 years.  I find ‘Rozanne’ will grow happily in sunshine or partial shade, but these plants will truly flourish in a really bright and sunny situation.  ‘Rozanne’ is not a fussy plant and given appropriate conditions, it’s incredibly easy to grow.  Plant ‘Rozanne’ in any moist, but well-drained soil.  Avoid planting ‘Rozanne’ in wet soils or waterlogged sites, as plants are unlikely to succeed in these conditions.  If your soil is soggy, look for plants suited to your conditions or consider building a raised bed to improve drainage.

Here’s Geranium ‘Rozanne’ growing in my old garden. I’ve grown this cultivar in full-on sunshine, partial shade, and deeper shade. This herbaceous perennial will flourish in full sunshine, in any moist but well-drained soil.

The Parma Violet-blue of ‘Rozanne’s flowers combine beautifully with apricot-pink, peach, yellow, gold, buff, orange, indigo, or white flowers, but almost any colour will look good alongside ‘Rozanne’.  This hardy geranium is a superb choice of plant to grow as a companion for roses.

Geranium ‘Rozanne’ flowers feature attractive central highlights and lots of pollen for solitary bees, bees, and other pollinating insects.

When Rozanne’s flowers start to fade, take a pair of scissors, and cut the stems down to ground level.  Your plant will soon produce a new dome of foliage, followed by fresh new blooms.  ‘Rozanne’ is an incredibly long-flowering plant.  ‘Rozanne’ is listed in catalogues as flowering from June until October; however, my ‘Rozanne’ plants bloom from the beginning of April until October.

In my garden, Geranium ‘Rozanne’ blooms from April to October. When the blooms start to tail off and your plant starts looking tired, take a pair of decent scissors in one hand and hold the stems in the other and cut back to ground level. If we’re enduring a drought, give your plant a water immediately after pruning.
