Range DescriptionEryngium alpinum is native to Austria, Liechtenstein, Croatia, France, Switzerland, Italy, and Slovenia (Euro+Med Plantbase 2006-2010). Easily recognizable and remarkable for its intense blue colour, the plant is emblematic of the alpine flora (Gaudel et al. 2000). The plant is cultivated and has been observed to escape from gardens.
In France, it is found in two regions: Rhône-Alpes and Provence-Alpes-Côte-d’Azur. It occurs at 42 localities which equal 38 locations. In Austria, it extends from Voralberg to Liechtenstein and from Kärnten to Slovenia. In Switzerland, the AOO is 74 km², but it is not clear whether it is introduced or native. There are a few small subpopulations scattered in the Alps in Slovenia and some are locally extinct. In Italy, there have also been local extinctions and the plant is now found in eight localities.
The AOO might be less than 2,000 km², but there is not enough supporting data for this assumption.
