Heather (Calluna)
Description
Calluna has small scale-leaves (less than 2-3 mm long) borne in opposite and decussate pairs, whereas those of Erica are generally larger and in whorls of 3-4, sometimes 5. The flowers emerge in late summer; in wild plants these are normally mauve, but white-flowered plants also occur occasionally. They are terminal in racemes with sepal-like bracts at the base with a superior ovary, the fruit a capsule. Unlike Erica, Calluna sometimes sports double flowers. Calluna is sometimes referred to as Summer (or Autumn) heather to distinguish it from winter or spring flowering species of Erica.
