Ethnobotany of Heracleum persicum Desf. ex Fisch. an invasive species in Norway or how plant names uses and other traditions evolve

摘要

BackgroundHeracleum persicum was introduced to Norway as an ornamental in the 1830′s. Towards the end of the 19th century, it started spreading outside gardens, later to become a frequent sight in the major towns and settlements of North Norway – and a veritable pest plant. During the last 100 years or so, a substantial ethnobotanical tradition related to the species has evolved, demonstrating that folk knowledge is not only forgotten and lost, but also charting new terrain.
