Calluna vulgaris known as heather is a low-growing perennial shrub blooming in purple shades in late summer. It is the dominant plant in most heathland and moorland and has become iconic of Scotland, often associated with the rocky highlands where it has grown profusely for centuries, sometimes in places where few other plants can survive. Heather is regarded in Scotland as being lucky and sprigs of it are often sold as charms or worked into bridal bouquets. Heather is also dyed and compressed with resin for jewellery. Poems and stories like Bonnie Auld Scotland associate heather and Scotland.
