 Link to Wikipedia, Medicago lupulina - "...A native of the old world, black medick is found throughout Europe, north Africa, and much of Asia, including India, China, and Korea. It thrives in dry limestone grounds and coastal sand dunes, where it suffers less competition from the other plants, and as such is found on many islands, such as Taiwan, the Canary Islands, and Madeira. The plant is naturalized throughout the United States, including Hawaii. Black medick is resistant to cold, and can be found on mountains up to 1,800 meters..."
