Native to northern Africa (i.e. northern Algeria, Egypt and Tunisia), Europe, northern and central Asia (i.e. Iran, Iraq, Turkey, Armenia, Azerbaijan, Georgia, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Mongolia, China, Japan, Korea and Taiwan) and possibly also North America (i.e. Canada, Alaska and the USA).
