The Siberian cranesbill ( Geranium sibiricum ) is a plant from the genus of geranium ( Geranium ) in the family of geraniaceae (Geraniaceae). It is very rarely grown in gardens.
description
The Siberian cranesbill is an annual to perennial herbaceous plant . The upper parts of the plant are hairy. The basal leaves are in a rosette. The 20 to 25 mm long and 35 to 75 mm wide leaves are deeply palmate and divided into five to seven lobes and the lobes are quite coarse and sharply toothed.
Compared to the other species of the genus, it forms relatively few flowers. A maximum of two flowers are formed in each leaf axil, but there can be four at the tip of the stem. The hermaphroditic, radially symmetrical , five-fold flower has a diameter of 1.0 to 1.4 centimeters. With a length of 4 to 5 mm, the egg-shaped sepals are about as long and occasionally even somewhat longer than the white to pink petals with purple stripes , which are also egg-shaped. The stamens are yellowish and the anthers are bluish. The scars are yellowish. The gap fruits are 1.4 to 1.9 cm long.
The number of chromosomes is 2n = 28.
Distribution and locations
The western limit of its occurrence lies in the catchment area of the Oder and in eastern Austria, although it rarely occurs at its area borders . Since the beginning of the 20th century, however, it has been observed that the range of the Siberian cranesbill is slowly shifting towards the west. A cause for this area expansion is not yet known.
The Siberian cranesbill predominantly populates light shrubbery near bodies of water and nearby wasteland. In Central Europe it is probably a kind of the Aegopodion or Alliarion associations. Like most cranesbills, the Siberian cranesbill needs a nutrient-rich clay soil. He also tolerates it when this clay soil is chalky and fresh.
