It is a [[genus]] with 422 [[species]]. ''Geranium'' [[Flower|flowers]] have five [[Petal|petals]]. The flowers can be coloured white, pink, purple or blue. Geraniums will grow in any [[soil]] that is not too wet. Geraniums can be [[Annual plant|annual]], [[biennial]], or [[perennial]] [[Plant|plants]]. These plants are often called '''cranesbills'''. They are found in [[Temperateness|temperate]] areas of the world and the mountains of the [[tropics]], but mostly in the eastern part of the [[Mediterranean region]]. Some [[caterpillar]]s eat geraniums. Several species of ''Geranium'' are [[gynodioecy|gynodioecious]].<ref>Hessing, M.B. 1989.

The species ''[[Geranium viscosissimum]]'' (sticky geranium) seems on the way to becoming [[carnivorous]]. Sometimes members of the genus ''[[Pelargonium]]'' are also called geraniums. ''Pelargonium'' species are also grown as garden plants. Sometimes members of the
