説明（英語）: Genus of one species of evergreen shrub found on acid moorland and lowland heaths from N. and W. Europe to Siberia, Turkey, Morocco, and the Azores. It bears dense racemes of bell-shaped flowers, in shades of red, purple, pink, or white. The calyces are normally 4-lobed, and longer than the corollas, but usually the same colour - features that help to distinguish heathers (Calluna) from heaths (Erica). Racemes on young plants may be short, 1-5cm (1/2-2in) long; medium, 5-10cm (2-4in); or long, over 10cm (4in). As plants age, the racemes become shorter. The leaves, borne in opposite and overlapping pairs, lying flat along the stems, are linear, slightly fleshy, and usually dark green, becoming purple-tinged in winter. There are more than 500 cultivars, all of which are good ground-cover plants. Heathers are very attractive to bees.

耐寒性（英語）: Fully hardy.
