Unlike Erica, Calluna sometimes sports double flowers.
They are terminal in racemes with sepal-like bracts at the base with a superior ovary, the fruit a capsule.
Stunning forested mountains and towering waterfalls, blackwater rivers and scenic inland lakes, white sand beaches and ancient island shores, treasured American historic sites and priceless cultural treasures.
Calluna is differentiated from Erica by its corolla and calyx each being in four parts instead of five.
Calluna has even smaller scale-leaves (less than 2–3 mm long).
