Origin From a botanical point of view, the alpine man's thistle (Eryngium alpinum) belongs to the Apiaceae, i.e. to the family of umbellifers. The alpine thistle occurs naturally exclusively in mountainous areas, in the Alps as well as in the Jura. It is native to Central Europe. Growth The alpine man-trefoil reaches a height of 50 to 80 centimeters. Like all members of the genus Mannstreu, this prickly perennial is classified as a thistle - it is also known as "Alpine thistle". Leaves The foliage consists of ovate to cordate basal leaves with unevenly toothed margins and often blue-white veined, lobed stem leaves. In the fall, alpine manure sheds its leaves. Flowers The flowering period falls in midsummer with July and August. Ovoid to cylindrical and also blue flower umbels develop on a stout and often slightly bluish flower stalk. They are surrounded by blue, slightly spiny, pinnately lobed bracts as well as a collar.
