Geranium Rozanne spreads into a low, leafy mound with large violet-blue flowers marked by purple veins and white centers. The blooms continue from early summer into fall, while marbled green foliage fills gaps at the front of borders or spills over containers.
Grow it in full sun or partial shade in moderately fertile, well-drained soil. Keep the soil evenly moist during active growth, though established plants tolerate some dryness. Remove flowered stems and old leaves to encourage fresh foliage and more flowers.
