Geranium is a genus of 422 species of flowering annual, biennial, and perennial plants that are commonly known as the cranesbills. They 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, palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white, pink, purple or blue, often with distinctive veining. Geraniums will grow in any soil as long as it is not waterlogged. Propagation is by semiripe cuttings in summer, by seed, or by division in autumn or spring.
Geraniums are eaten by the larvae of some Lepidoptera species including brown - tail, ghost moth, and mouse moth. At least several species of Geranium are gynodioecious. The species Geranium viscosissimum (sticky geranium) is considered to be protocarnivorous.
