Haller's primrose ( Primula halleri ) is a species of plant that belongs to the genus of primroses ( Primula ). The specific epithet honors the Swiss polymath Albrecht von Haller .
description
The herbaceous perennial plant reaches heights of 10 to 30 centimeters. It has basal leaves . The leaves, which are curled backwards when young, are oblong, ovate and wrinkled, their upper side is green and wrinkled, the underside whitish-floury.
The sturdy stem , powdered floury at the top , has a multi-flowered, golden inflorescence . The flowers are on stems 4 to 15 millimeters long. The bracts are equally long and sub-sublime. The five-lobed crown with a yellow throat is pinkish-purple and 15 to 20 millimeters wide. The corolla tube is three times as long as the chalice.
The flowering period extends from June to July.
The similar flour primrose ( Primula farinosa ) has calyxes and corolla tubes of approximately the same length and crowns with a width of 8 to 15 millimeters as distinguishing features.
The number of chromosomes is 2n = 36.
Occurrence
The distribution area covers large parts of Europe from France via Central Europe and Southeast Europe to Eastern Europe . It populates the Alps , the Carpathians and the Balkan Peninsula . In the Alps, this type of plant occurs scattered, especially in the southern and eastern parts. This species prefers alkaline soils and can be found subalpine to alpine up to altitudes of 2900 meters on grass, in crevices and on rubble.
In Austria , moderately moist grasslands or damp rock crevices are populated in the federal states of Carinthia , Salzburg , Tyrol and possibly also Vorarlberg .
Locations and distribution in Central Europe
Haller's primrose needs lime and humus rich, fresh and loose soil. She prefers warm, sunny places.
It colonizes somewhat gappy alpine lawns and solidified rubble, but it also goes into crevices in the rock. It usually grows at altitudes between around 1800 and 2500 m, it also goes locally lower or even higher up to 3000 m.
In Central Europe it is generally rare; it occurs in the Graian Alps, in the Valais, in the Simplon, in the Maggia Valley, in the Upper Engadin and in the Southern Limestone Alps to the Balkans.
Systematics
The Haller Primrose was in 1775 by Johann Friedrich Gmelin in Onomatologia botanica completa described . A synonym for Primula halleri is Primula longiflora All.
