We often hear debates as to whether this scented geranium actually repels mosquitos, but this variety is worth planting if only for its fresh beautiful foliage and pink-hued flowers. Scented geraniums generally grows to 24 inches tall and almost a wide, forming a compact mound of heavily serrated, almost ruffled foliage. Drought tolerant once established, they thrive in the heat and perform best in well-draining soil. They add lovely textural interest to container planters, hanging baskets and sunny borders all summer long.
