A biennial or perennial species of dry often disturbed soils that is native to Europe and introduced into North America. In the Nordic countries it only occurs as an adventitious species and occurrences are often short-lived.

The foliage of this plant sometimes is used as a vegetable in salads. Doesn't taste too bad, actually.

Specimen collected in Oslo, Norway 12 August, 2011.
