Heather / Ling
Calluna vulgaris is the sole species in the genus Calluna in the family
Ericaceae. It is the true Heather of Europe, and National Flower of Norway.
However it also has an affiliation to Scotland. 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.
It is separated from the closely related genus Erica by its four-parted corolla and calyx. The flowers emerge in late summer, and in the wild species these are usually in purple or mauve shades.
