Facts

Common stork's-bill is native to Europe, northern Africa, and central and western Asia. It is occasionally introduced in North America, where it has been collected in Pennsylvania and Massachusetts. The Massachusetts collections resulted from dumping of wool waste from nineteenth-century wool carding factories, or possibly as escapes from cultivation.
