description
The Western Alpine clover is a bare, hibernating green, perennial, herbaceous plant that reaches heights of 5 to 20 centimeters. The tough taproot tastes sweet. All leaves are basal and divided into a petiole and a leaf blade. The petiole has a length of about 5 centimeters. The leaf blade is pinnate in three parts. The three leaflets are linear-lanceolate with a length of about 10 centimeters and can be described as having entire margins.
The flowering period extends from June to August. The cephalic inflorescence has a diameter of about 3 to 5 centimeters and contains three to twelve stalked, relatively large flowers. The hermaphrodite flowers, which have a balsamic scent when the sun is shining, are zygomorphic and five-fold with a double flower envelope . The bald and ten-veined calyx tube is longer than the flower stalks. The flesh-pink to purple-red petals are between 18 and 25 millimeters long and protrude eight times over the calyx tube.
The number of chromosomes is 2n = 16.

It prefers altitudes of over 1700 meters, but it also goes a little deeper locally. The eastern limit of its distribution roughly corresponds to an imaginary line from Arlberg to Lake Garda . To the west of this line it is absent almost everywhere in the Northern Limestone Alps and in larger areas in the Southern Limestone Alps; overall it occurs in Central Europe scattered.
The Western Alpine clover thrives best on lime-free, acidic, moderately nitrogenous soils that are not too shallow . It occurs in Central Europe in alpine climates . The western alpine clover colonizes mats rich in bristle grass and loose dwarf shrub stands. Its natural habitats include grass and crooked sedge lawns .
