Geraniums

Geraniums belong to the Geraniacea family, and are typically found in temperate and subtropical regions. Because of their long, beak-shaped fruits they are commonly better known as crane's-bill. Geraniums are being cultivated for the use as ornamentals, but also because of their aromatic oils, which are used for producing perfumes and flavorings. The flower consists of five petals that can be blue, purple, white, or pink.[1]

There are about 730 different species, but they often get confused with the Pelargonium species from South Africa, which have kind of irregular, spurred flowers.[2]
