The alpine Eryngo ( Eryngium alpinum ) is a plant type from the family of the Umbelliferae (Apiaceae). It is also known as the "blue thistle" or "anhakn".
features
The herbaceous perennial plant reaches stature heights of about 50 to 70 cm (up to 80 cm). The plant is very similar to thistles. The stem is branched and grooved in the flower area.
The soft basal leaves have a very long stalk. Their shape is undivided, triangular or oval with a heart-shaped base. The edge is serrated unevenly. The palm-shaped, pinnate stem leaves are arranged alternately and have thistle-like spines.
The flowers are two to three millimeters long and sit tightly packed in a round, cylindrical inflorescence . Noteworthy are the amethyst-colored, bluish bracts that form an extra- floral display device that attracts the insects. The bracts are pungent and serrated.
Flowering time is from July to September.
The number of chromosomes is 2n = 16.
Occurrence
The Alpen-Mannstreu originally occurs in France, Italy, Switzerland, Austria, Liechtenstein, Slovenia, Croatia, Bosnia-Herzegovina and Montenegro. The main distribution of this species is in the western Alps , in the Jura (mountains) and the Dinaric mountains. As location calcareous soils, are tall herb corridors and Wildheuplanggen 1200 bis 2500 m preferred height. It occurs mainly in societies of the Caricion ferrugineae and the Adenostyletalia.
In Austria the species occurs very rarely in south-west Carinthia (western Carnic Alps ) and has also been found in Vorarlberg.
The plant is rarely cultivated as an ornamental plant. It is sometimes anointed like in South Tyrol (Ultental).
Others
The thorny umbel envelope closes when it is wet and dark and repels snails, caterpillars and grazing cattle.
