The Royal Horticultural Society actually named Rozanne as the best Hardy Geranium! Its large 2 1/2" violet-blue blooms with white centers lower profusely from late spring through late fall, and it tolerates heat and humidity remarkably well, performing beautifully even in Georgia summers (though it does like afternoon shade in the South). Plant in ordinary garden soil that is well-drained, and water when dry for months of blooms and years of pleasure! Zones 5-8. Ships in 3" pot. Geranium 'Rozanne' PP12175.
