Pelargonium is a plant of South African origin, from the botanical family of Geraniaceae, very widespread in our country and includes about 250 species. The zonal geranium (scientific name: Pelargonium zonale) is so called because of the dark area present in the center of the petals, similar to a spot with shades. The flower can grow on the windowsills and balconies, as long as the place is ventilated and sunny, in fact its presence in the South is more frequent. The plant is bushy and can even exceed one meter in height. It begins to bloom in March-April and continues until the end of October. The leaves are opposite, velvety and lobed. The flowers have 5 petals, 2 of which are erect and 3 curved downwards. The colors vary and range from white to intermediate shades of pink, red and salmon.
