Pelargonium, also known as geraniums, is a genus comprising around 200 species of perennials, succulents, and shrubs, native mainly to South Africa. Not to be confused with the common garden geraniums (Pelargonium spp.), they are grown primarily for their attractive foliage and flowers. The leaves are usually pinnate or deeply incised, and some species have foliage that is highly fragrant when crushed.
The scent profiles of Pelargonium are diverse and can vary significantly between species. They often emit strong, aromatic fragrances which can include rose, mint, lemon, apple, and even nutmeg or other spices, depending on the specific variety and the oils present in the leaves and stems. Pelargonium graveolens, for instance, is renowned for its robust rose scent and is commonly used in essential oils and perfumes.
The delightful variety of fragrances produced by different Pelargonium species makes them highly valued in aromatic and horticultural applications. The flowers themselves are also notable, typically characterized by five-petaled blooms that appear in a range of colors including white, pink, purple, and red. These plants are popular in gardens and terraces for their visual appeal and the pleasant aromas they provide, enhancing the sensory experience of the space.
