Geranium ‘Rozanne’ – Award-Winning Hardy Geranium with Exceptional Flowering
Geranium ‘Rozanne’ is one of the most popular and reliable hardy geraniums, celebrated for its exceptionally long flowering period and vibrant colour. Producing large, open violet-blue flowers with a pale centre, it blooms continuously from late spring right through to the first frosts.
The flowers are held above a mound of deeply cut green foliage, creating a relaxed, informal look that works beautifully in a wide range of planting styles. As the season progresses, the foliage may take on subtle autumn tones, adding further interest.
Its naturally spreading habit makes it ideal for ground cover, softening the edges of borders, and weaving through other plants. It also performs well in containers, where its trailing growth can spill attractively over the edges.
Thriving in sun or partial shade, ‘Rozanne’ is adaptable to most well-drained soils and is notably resilient, coping well with varying conditions once established.
Low maintenance and easy to grow, it benefits from a light trim in mid-season to encourage fresh growth and even more flowers.
Free-flowering, versatile, and full of colour, Geranium ‘Rozanne’ is an outstanding choice for long-lasting impact in the garden.
