Cross-leaved Heath

''Erica tetralix'' is a species of heather found in Atlantic areas of Europe, from southern Portugal to central Norway, as well as a number of boggy regions further from the coast in Central Europe. In bogs, wet heaths and damp coniferous woodland, ''Erica tetralix'' can become a dominant part of the flora. It has also been introduced to parts of North America and other parts of Europe such as Austria and Switzerland.
