Geranium Rozanne® is the longest blooming and most prolific blue-flowered Geranium in our garden. Flowers start in early summer and continue through midsummer’s heat into autumn on fast-growing plants, which are spreading but not sprawling and make an attractive ground cover. The lavender-blue blossoms, up to 2” in diameter, contrast beautifully against finely cut leaves that are deep green and slightly marbled in summer and a handsome russet in autumn. The Perennial Plant Association’s Perennial Plant of the Year (2008) and winner of the Royal Horticultural Society’s Plant of the Centenary at the Chelsea Flower Show (2013). ‘Gerwat’ PP 12,175.
This is the true Geranium, not to be confused with the annual Pelargonium one sees everywhere in summer. Perennial Geraniums are lovely plants that grow in full sun or partial shade (required in the South and in the warmer areas of western Zones 9 and 10) and need soils with good drainage.
