[Wikipedia] Europe, Asia, Africa Native, Weed Status: It is native to Europe, western Asia and northern Africa and naturalised in southern Australia, New Zealand, and southern South America. Unlike other Fumaria species which are known as weeds of crops and agricultural areas, Fumaria capreolata can become naturalised in areas of natural vegetation and smother low-growing plants, becoming an environmental weed.
