Scented Geraniums are made up of several species of Pelargoniums . Leaves of scented geraniums possess lemon, rose, peppermint, nutmeg, apple and other fragrances and are excellent houseplants. Flowers on scented geraniums are not as showy as the other geranium types and are normally white, pink, or lavender. Since the citronella oils are released only when the plant tissue is rubbed or crushed, plants growing in containers on the patio or deck will not repel mosquitoes. Geranium Culture Geraniums for outdoor use should be planted outside after the danger of frost is past in your area.
Geraniums prefer fertile, well-drained soils that are slightly acidic.
The plants should receive at least six hours of sunlight daily. Plants in shady areas will bloom less and are more susceptible to disease. Regular watering is required for most geraniums. During dry periods, a deep soaking once a week is usually sufficient for bedding geraniums, while container plantings often require more frequent watering. If possible, avoid overhead watering because wet foliage encourages disease development.
