Erica cinerea (bell heather, or heather-bell) is the most common specie of ericaceae, native to western and central Europe. We find it here together with Calluna vulgaris (known as common heather, ling, or simply heather).
Contrary to its name (cinerea meaning "ash coloured" in latin) its bell-shaped flowers are purple (rarely white) and produced in mid- to late summer.
Erica cinerea mostly occurs on moors and heathland with relatively dry, acidic, nutrient poor soils.
Like blueberry and cranberry, bell heather contains arbutin, a traditional treatment for urinary tract infections.
