Celebrate garden royalty with Geranium ‘Rozanne’, crowned RHS Plant of the Century at Chelsea Flower Show! This exceptional hardy perennial produces a profusion of vivid violet-blue blooms with soft white centres from early summer right through to the first frosts. Its lush, spreading foliage forms a beautiful ground cover, making it ideal for borders, underplanting, or spilling over containers. Loved by pollinators and gardeners alike, Rozanne is low-maintenance, long-flowering, and incredibly resilient—a true garden treasure that offers months of colour and beauty.

How to care for Geranium 'Rozanne':

Incorporate plenty of organic matter when planting and water well in dry weather, especially newly established plants. Apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant to help seal in moisture, feed the soil, and reduce the need for weeding.

Deadhead spent flowers regularly to encourage continuous blooming. If the plant becomes too leggy or untidy later in the season, trim lightly to encourage fresh growth and more flowers.

During the first growing season, regular watering is crucial to establish deep roots. Once established, 'Rozanne' shows commendable drought tolerance. A feed of balanced, slow-release fertiliser in spring will support its prolific blooming.

One of the many virtues of this hardy geranium is its resistance to pests and diseases, making it a low-maintenance choice for gardeners. To encourage a second flush of blooms, trim the plant back by one-third in midsummer (aka ‘The Chelsea Chop’).

At the end of the growing season, cut it back to ground level in late autumn or early spring. Every 3-4 years, consider dividing the plant in spring to maintain its vigour.
