Pelargonium hortorum
Pelargonium hortorum, commonly known as the zonal geranium or simply geranium, is one of the most popular ornamental plants worldwide. It is distinguished by its striking flower clusters which, in this variety, present a very elegant pure white. Its leaves are fleshy, rounded, and often display a dark, horseshoe-shaped band, a characteristic that gives it its "zonal" name. It is a plant highly valued for its ability to flower continuously during warm months.
It belongs to the Geraniaceae family and originates from South Africa, although current garden specimens are complex hybrids developed to improve their resilience and coloration. In its natural habitat or in Mediterranean climates, it grows as a sub-shrub with stems that tend to become woody over time. It prefers well-ventilated locations and soils with excellent drainage to prevent rotting of its succulent stems, being able to tolerate short periods of drought once established.
Its cultivation is extremely simple, making it the ideal choice for balconies, terraces, and windowsills. In addition to its aesthetic value, geraniums are known for their resistance to many common garden pests. They are propagated with great ease through stem cuttings, a common practice among enthusiasts to multiply the plant. Although it is an outdoor plant, it can be kept in very bright indoor spaces during winter in cold climates.
