Geranium, commonly known as cranebill, is a genus of 422 species of flowering annual, biennial, and perennial plants that are found throughout the temperate regions of the world and the mountains of the tropics, but mostly in the eastern part of the Mediterranean region. The long, deeply parted and cleft leaves are broadly circular in form, and its flowers have five petals, woolly at base, with colors ranging white, pink, purple or blue, often with distinctive veining. Geraniums will grow in any well-drained soil. Propagation can occur by cuttings, seed, or division. The genus name is derived from the Greek for crane, due to the appearance of the fruit capsule of some of the species. Species in the Geranium genus have a distinctive mechanism for seed dispersal. This consists of a beak-like column which springs open when ripe and casts the seeds some distance.
