The Creeping gypsum herb ( Gypsophila repens ), horticultural dwarf's breath , is a plant from the family of the Pink family (Caryophyllaceae).

description

It is a perennial herbaceous plant whose prostrate to ascending stems including the inflorescences reach heights of growth of 10 to 25 cm.

The narrow, lanceolate leaves are about 2 cm long and well under 1 cm wide and, like the stems, glabrous and blue-green.

The flowers are white, sometimes reddish, and about a centimeter in diameter. The chalice is bell-shaped and split up to the middle with five tips. The petals are rounded at the front to slightly edged. The stamens are slightly shorter than the petals.

Flowering time is from May to September.

The number of chromosomes is 2n = 34 or 36.

Creeping gypsophila ( Gypsophila repens )

Occurrence

The range of the species includes Spain, France, Italy, Switzerland, Germany, Austria, Slovenia, Poland and Slovakia. Creeping gypsum is quite common in the Limestone Alps . Otherwise it rarely occurs in other higher mountains in Europe ( High Tatras , Apennines , Harz ). In its 1912 edition, the Illustrierte Flora von Deutschland, launched by Christian August Friedrich Garcke, reports on a larger deposit near Walkenried in the Harz Mountains.

The creeping gypsum herb grows wild on calcareous or gypsum-rich soils, on limestone rubble or in dry grass in limestone areas. Usually it lives in the alpine region; However, seeds are regularly washed down into the valleys or the Alpine foothills and germinate there successfully. Otherwise it can be found at altitudes between 1300 and 3000 m above sea level. Cultivated species also thrive on any soil that does not retain water and are therefore often kept in stone beds. It is a character species of the class Thlaspietea rotundifolii and occurs particularly in societies of the associations Petasition paradoxi and Epilobion fleischeri.

ecology

This type of plant is a so-called rubble: from the strong taproot arise numerous, often woody branches, which, after the leaves have fallen off, take root and become lying rhizomes ("rhizomes"). The upright, delicate stems with the fragrant flowers rise from them. Although the individual flowers are small, the large abundance attracts insects. He is a hibernator , seeds ripen and germinate at 2300 m above sea level.
