The wall gypsum herb ( Gypsophila muralis ), also called field gypsum herb, is a member of the carnation family (Caryophyllaceae). It blooms from July to October.
description
The annual herbaceous plant reaches a height of about 5 to 20 cm. The stem is usually upright and forked and has no non-flowering shoots. It is short-haired at the base, otherwise bald. The leaves are more or less linear in shape. The petals are usually notched or edged and colored light purple. They have darker veins and are about twice as long as the sepals. These are connected to one another by dry-skinned strips. The seeds are kidney-shaped.
The flowering period is June to October.
The number of chromosomes is 2n = 34.
Possibility of confusion
The field gypsum herb differs from the similar saxifrage rock carnation ( Petrorhagia saxifraga ) in that it lacks the scaly bracts at the base of the calyx. Carl von Linné already pointed out this difference in 1753 in the first description of the species in his work Species plantarum, Volume 1, page 408.
Occurrence
Location claims and socialization
The wall gypsum grows in gullies, on fallow land, on banks, ditches or wet paths. It prefers moist or at times wet, more or less nutrient-rich, mostly lime-free, mostly sandy loam and clay soils. It is a waterlogger and somewhat heat-loving. In Central Europe it is a species of the order Cyperetalia fusci and occurs particularly in societies of the Juncenion bufonii sub-group.
General distribution
Gypsophila muralis occurs from southern Scandinavia to southern Europe. East to Asia Minor, the Caucasus and Siberia. It is a Eurasian floral element. In Austria the wall gypsum is found scattered or rarely in the colline area, in Switzerland it can only be found in places.
Distribution in Germany
The wall gypsum is very rare in the northern part of Germany and is absent over long distances. In the central and southern part it occurs scattered to relatively common.
Species protection
Endangerment in Germany: Category 3: endangered!
The species should not be collected because of its endangerment and rarity!
