Calluna vulgaris (also known as Ling) is the sole species in the genus Calluna in the family Ericaceae. It is the true Heather of Europe, an National Flower of Norway. However it also has an affiliation to Scotland and is the most common heath in the United Kingdom. It is a small perennial shrub growing to 20-50 cm tall (rarely to 1 m), and is found widely in Europe and Asia Minor on well-drained acidic soils in open sunny situations and in moderate shade. It is tolerant of moderate grazing and can regenerate following occasional burning. It is often managed in nature reserves using a light burning method. It is a common, often dominating, component of heath and moorland habitats, and also on peat bogs and in open pine forests.
