The genus ""Calluna"" was formerly included in ""Erica"" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. ""Erica"" is sometimes referred to as ""winter (or spring) heather"" to distinguish it from ""Calluna"" ""summer (or autumn) heather"". The Latin word ""erica"" means ""heath"" or ""broom"".
