Stellaria graminea
Grass chickweed ( Stellaria graminea )
The grass - chickweed ( Stellaria graminea ), also called grass chickweed, is a plant of the family Caryophyllaceae ( Caryophyllaceae ). It is similar to the Great chickweed, but has narrower leaves and its almost to the ground split petals are longer than the sepals.
Appearance
The perennial herbaceous plant reaches a height of about 10 to 50 times to 80 inches and forms a loose lawn. The square, branched stems looks pretty limp. The narrow leaves are linear - lanceolate, slightly ciliate at the base but otherwise bare and grass-green color. They are about four inches long and grow in pairs opposite, sessile, ascending only but soon falling on the stem.
The inflorescence is spread and input annoying. The branches are often formed knickbogig. The small flower has a diameter of rarely more than 12 mm and has three pen. The five sepals are three annoying ciliate and about 3 to 5 mm long. The white petals are almost down to basically two columns and as long as or slightly longer than the sepals. The flowering season is from May to July.
The green, oblong capsule fruit is slightly longer than the calyx. It opens up five jagged and there dismisses the reddish brown grooved one to 1.2 millimeters large seeds.
Distribution and ecology
The grass - chickweed grows in sparse mountain meadows and rough grazing, along roads and in fields. In nutrient-poor wet meadows and bogs you find them. It prefers moderately fresh, moderately nutrient-rich, calcium-poor, neutral, moderately acidic, humus-rich, predominantly sandy loam soil. It is an indicator acidification and a pioneer plant.
Stellaria graminea occurs in the temperate zones of Europe and Western and Central Asia up to altitudes of about 1,200 meters above sea level. before. To North America, it was introduced by humans. Frequently throughout Germany, especially in the calcium-poor areas. In Austria and Switzerland, the species is widespread and commonly found.
This species is found almost exclusively in larger, but rarely was forming groups. Your fertilization occurs through self - or insect pollination, the seeds are dispersed by the wind on. The deciduous, perennial Schaftpfanze drives after the winter break on rootstock from new.
The chromosome number is n = 13
