Potentilla neumanniana

Spring cinquefoil ( Potentilla neumanniana )

The Spring cinquefoil ( Potentilla neumanniana, synonym: Potentilla tabernaemontani ), is a mostly used in Central Europe and frequently occurring Rose family ( Rosaceae ). It blooms from March to May, sometimes in the late summer and fall a second time.

Appearance

This species is persistent and often forms large, carpet-like growth forms. The basal leaves are finger- shaped and consist of five to seven wedge-shaped to inverted egg-shaped leaflets. These are 1-3 cm long and have two to five teeth each side. The free part of the stipules of the basal leaves is very narrow-linear to lanceolate ( unlike the Reddish cinquefoil ). The flowering shoots grow laterally from the axils of last year's, the heyday partially past basal leaves. You are decumbent, ascending to the tip, 5-15 cm long and have several stem leaves. The inflorescence is 3-10 flowered, and often branches from the axils of the lower stem leaves. The flowers are yellow and have a diameter of 10-18 mm. Only those plants are neumanniana as Potentilla called that do not have hair star ( see, eg, sand cinquefoil ). The hair only consists of simple, 2-3 mm long hairs ( " Striegel hair " ), most of which are directed forward, rarely, almost stand-off. In the upper part of the flowering shoots and on the petioles, there are shorter, curved hairs, sometimes short glandular hairs.

Dissemination

Site conditions

Potentilla neumanniana grows on dry sites such as rock heads, open gravel and sandy soils, even on vineyard walls, roads and embankments and roadsides.

Popularization

The species is up to Belarus and Bulgaria in the east, especially in temperate Europe from northern Spain in the west. North to Scotland, Central Norway, Estonia, Karelia, in the south of Corsica, Italy to Apulia, on the Balkan Peninsula to Macedonia.

Distribution in Germany

The Spring Cinquefoil is very common in Germany. In northern Germany it is very rare.

Others

Pollination of flowers carried by insects.

The Spring Cinquefoil is particularly diverse and variable. Until now, no satisfactory classification of the species is managed. In part, up to 10 varieties are distinguished and these in turn divided into several forms. However, almost everywhere occur transitions between the different forms.
