Botanical name: Pelargonium hortorum
Garden Geraniums (sometimes called zonal geraniums), sold at local plant nurseries are actually Pelargoniums. They are perennials bearing numerous bold, beautiful clusters of hot pink, deep red, salmon, or white flowers, with vibrant deep green leaves which are equally as pretty.
GardenGeraniums are easy to grow, and are not very picky about soil type, but it must be well-draining. They are perfect for containers or planting directly in the ground. They can also be grown indoors with at least four hours of direct sunlight.
They require minimal watering except during hot, dry spells, and providing good air circulation will prevent powdery mildew, and other diseases. Geraniums thrive in full sun, but will also do well in partial shade. Most geraniums are native to southern Africa, and are best suited to very warm climates. However, some are hardy to Zones 7-8.
They can be propagated by taking cuttings in summer, and by division in spring or fall, and can grow to 3’ in height.
