The Pulsatilla grandis or Large Küchenschelle or wholesale Küchenschelle ( Pulsatilla grandis ) is a plant of the genus Kuhschellen ( Pulsatilla ) in the family Ranunculaceae (Ranunculaceae). It is sometimes combined with the common pasque flower and other clans as a species and then as a subspecies Pulsatilla vulgaris subsp. grandis led.

description

The pasque flower is a perennial herbaceous plant . In the blooming state it has a stature height of 10 to 15 (rarely only 5) centimeters, at fruit maturity 30 to 40 (rarely up to 50) centimeters. In contrast to the common pasque flower, their basal leaves only appear towards the end of the flowering period. The leaves are double (rarely triple) pinnate and consist of 40 to 90 broad-linear-lanceolate, four to seven (rarely two to twelve) millimeter wide sections.

In contrast to the otherwise very similar common pasque flower ( Pulsatilla vulgaris s. Str.), The flower stays upright even in cloudy and cold weather. The tepals are 35 to 45 millimeters long. Flowering time is March to April, rarely in February. The pollination is done by bees and bumblebees.

The fruits are flat, single-seeded nuts.

The number of chromosomes is 2n = 32.

distribution

The Pasque Flower has a Pannonian-Illyrian distribution.

In Germany it is only native to Bavaria and Thuringia and, since listed here as a subspecies of Pulsatilla vulgaris , it is strictly protected under the Federal Nature Conservation Act. In Austria it occurs frequently to scattered in the Pannonian region in the federal states of Burgenland, Vienna and Lower Austria, but the locations are rare. It is considered endangered and is under nature protection.

It grows on calcareous dry grassland, in grassy steppes and in black pine forests. It occurs up to the submontane altitude level . In Central Europe it thrives in the company of the Adonido-Brachypodietum and Pulsatillo-Caricetum humilis and is a national character species of the order Festucetalia valesiacae.

Systematics

The pasque flower is partly listed as a separate species, Pulsatilla grandis , partly as a subspecies of the common pasque flower iw S. ( Pulsatilla vulgaris s. Latin). As a species it leads the Austrian excursion flora from 2008, as a subspecies FloraWeb and Schmeil-Fitschen.

In Upper and Lower Austria, the two clans form transitional forms.

use

The species is rarely used as an ornamental plant for perennial beds and rock gardens and as a cut flower. In the 'Budapest Variety' variety, the entire plant has golden yellow hairs.
