Safety Overview
1.Calluna Vulgaris — At a Glance
Calluna vulgaris, commonly known as Heather or Ling, is a monotypic genus in the Ericaceae family, widely recognized for its ecological dominance in moorlands and heathlands across Europe and parts of Asia, and naturalized in North America. This resilient evergreen dwarf shrub typically grows to a height of 20 to 50 centimeters, though it can reach up to 1 meter in sheltered locations. Its morphology is characterized by tiny, scale-like leaves, arranged in opposite decussate pairs, closely pressed against the stem, which helps reduce water loss in its often exposed habitats.
The plant produces abundant small, bell-shaped, typically purple-pink flowers, though white and crimson varieties also exist. These flowers are arranged in dense terminal racemes, blooming profusely from late summer through autumn, providing a crucial nectar source for bees and other pollinators. Calluna vulgaris thrives in acidic, nutrient-poor, well-drained soils, often forming extensive carpets that define the landscape of its native regions.
Its robust nature and attractive flowering make it a popular ornamental plant, while its historical and contemporary medicinal uses are deeply rooted in European herbal traditions, valuing various parts of the plant for their therapeutic properties.
