The brook chickweed ( Stellaria alsine ), also called spring chickweed , is a species of plant in the carnation family (Caryophyllaceae).
Appearance
This herbaceous perennial plant reaches heights or length of about 10 to 40 cm. The leaves are sessile or short-stalked, elongated-lanceolate, pointed, broadest in the middle, single-nerved and slightly ciliate at the base. They are bluish green in color and juicy.
The inflorescence is usually multiple forked. The bracts are glabrous and dry-skinned on the edge. The petals are white, two columns almost to the base and about 0.75 times as long as the calyx, which is funnel-shaped at the base. The sepals are about 2.5 to 3.5 mm long. It blooms from May to July.
The seeds are about 0.6-0.8 mm in length and are weakly ribbed.
The number of chromosomes is 2n = 24 or 26.
ecology
The plant is self-sowing, on paths there is also the spread of treads. Fruit ripening is from July to September.
Location claims and distribution
The brook chickweed grows in spring corridors and spring niches, on forest paths and ditches. It prefers seeping wet, more or less nutrient-rich, lime-poor, neutral-moderately acidic, humus-rich, sandy or pure loam and clay soils. It is a partial shade plant. In Central Europe it is a character species of the Cardamino-Montion association, but also occurs in the Carici-Fraxinetum from the Alno-Ulmion association or in the Stellario-Scirpetum setacei from the Nanocyperion association. In the Allgäu Alps, it rises to an altitude of 1850 meters.
Stellaria alsine is native to Europe, North Africa, Madeira, India to East Asia and North America. It is a Eurasian-suboceanic floral element. In New Zealand, Chile and Indonesia it is a neophyte.
In Austria it occurs scattered to moderately common, in Switzerland it is only widespread in places.
The Bach chickweed occurs all over Germany. It is also found very often in places.
