Also called Perennial Cornflower and Mountain Knapweed, C. montana is native to central and southern Europe, and was introduced into gardens before 1596. William Robinson, the famous proponent of wild gardening in Victorian England, wrote about C. montana in The English Flower Garden (1883): "There is a white and a red variety, all thriving in borders, margins of shrubberies, or the wild garden in any soil".
