description

Five-fingered stem leaf (top and bottom)
Stipules (top and bottom)
The leaves are densely tomentose gray to white underneath, the leaf edge is rolled up.
inflorescence
Five-fold flower with yellow petals

The silver cinquefoil is a perennial herbaceous plant that usually reaches heights of 20 to 30 (10 to 50) centimeters. A rhizome is formed. The ascending stem is hairy white tomentose. The many leaves that are basal and distributed on the stem are fingered and serrated in five to seven places. The underside of the leaves is dense and the upper side is only thinly haired with white felts. The leaflets of the stem leaves are rolled down at the edge, deeply irregularly divided and usually tapering to a point.

The floriferous inflorescence is a more or less even bouquet. The hermaphrodite, radial symmetry flowers are five-fold and have a diameter of 9 to 12 mm. The free, yellow petals are 3 to 5 mm long and have weak margins.

The number of chromosomes is 2n = 14, 42 or 56.

ecology

As a hemicryptophyte it survives in cold winter areas, in southern regions it can also be partly evergreen. This type of plant avoids lime and is a grassland plant .

The silver cinquefoil is pollinated by insects , especially beetles , two-winged birds (i.e. flies and mosquitoes ) and hymenoptera such as bees and bumblebees . The flowering period extends from June to October.

Its long-lived seeds are spread by shaking or by digestion (e.g. by insects). Since the seeds can also arise without fertilization , i.e. through apomixis , there are numerous different clans that are also connected by intermediate forms.

Occurrence

The silver cinquefoil is not only found in Europe, but also in parts of Western Asia and North America. It occurs frequently throughout Germany.

The silvery cinquefoil thrives on roadsides, railway systems, gravel pits and rock corridors. Dry, moderately fresh, sandy to gravelly ruderal spots are preferred. It thrives in societies of the Sedo-Scleranthetea class, more rarely in those of the Festuco-Brometea class.
