Geranium L. - (cranesbills)
This genus is widely distributed and contains around 400 species of herbaceous plants or shrubs. Some are grown as ornamentals but other are considered agricultural weeds like Geranium carolinianum which affects crops like groundnuts or strawberries in North America and other regions.
The genus is closely related to the genus Pelargonium but is more often found in temperate regions.
