Cross-leaved heath, also known as Erica tetralix, is a species of flowering plant that belongs to the Ericaceae family. This beautiful heath is characterized by its distinctive four cross-shaped leaves and its pink-purple bell-shaped flowers that bloom from June to September. Some commonly used synonyms for cross-leaved heath include St. Dabeoc's heath, bog heath, or moor heath. In the United States, it is sometimes called cranberry heath, but this can be confusing, as it is different from the cranberry plants that produce cranberries. Cross-leaved heath is native to Europe and Western Asia and can be found mainly in bogs and moors, making it a key plant to protect in conservation efforts.
