About

Galeopsis angustifolia, red hemp-nettle, is an annual plant that is native to western Europe and increasingly occurs as a casual in eastern Europe. Its wild habitat is in montane scree in the Alps and Pyrenees, or on coastal shingle, but it is widely established on waste ground, arable fields and gravelly substrates. It was much more common on farmland in the past, where it was sometimes confused with Galeopsis ladanum.

Where it grows

Red hemp-nettle is a western European plant, expanding its range in recent years into eastern European countries such as Hungary and Ukraine, where it is considered a kenophyte (recent introduction) in man-made habitats such as railway lines. It is classified as native in rocky mountain areas in Poland but a recent introduction elsewhere. The core of its native range is from the Alps to the Pyrenees, where it is native on montane screes.
