Seeds

The saxifrage rock carnation is a wintering green, perennial herbaceous plant and reaches heights of 10 to 30 centimeters. It grows in dense grass with prostrate to ascending, richly branched stems . The leaves are arranged opposite one another on the stem. The leaf blade is narrow-linear with a length of up to 1 centimeter.

The flowering period extends from June to September. The flowers are arranged in paniculate inflorescences . There are four outer calyx scales per flower . A leaflet cover is missing. The hermaphroditic flowers are radial symmetry and five-fold with a double flower envelope . The five sepals are 4 to 6 millimeters long and fused together like a bell. The five petals are 5 to 10 millimeters long, pink or whitish, with darker stripes and shallow edges. There are ten stamens . There are two styluses .

The capsule fruit is four-toothed and 5 to 6 millimeters long.

The number of chromosomes is 2n = 60.

ecology

The saxifrage rock carnation is a chamaephyte .

The relatively small flowers produce plenty of nectar . They are mainly visited by flies and small bees, and occasionally butterflies.

Occurrence

The distribution area of ​​the saxifrage rock carnation extends from southern Europe to central Europe , eastern Europe and the Middle East. Their main distribution is in the Mediterranean area and in the Middle East . In North America it is a neophyte .

It settles in the Franconian and Swiss Jura , occasionally in the Northern Limestone Alps and in the central and southern Alpine valleys in places with a particularly mild climate, dry meadows and patchy lawns on rock debris . In the Jura is very rare to find them in the Alps rare. In Lower Austria and Burgenland it appears absent-minded.

The saxifrage rock carnation needs lime-rich or calcareous , very loose soils , which can be sandy or stony, may be poor in fine earth and must be dry and warm. It prefers altitudes between 50 and 1500 meters. It thrives in societies of the Sedo-Scleranthetalia order, but also occurs in gappy societies of the Festuco-Brometea class.

Taxonomy

It was first published in 1753 by Carl von Linné under the name ( Basionym ) Dianthus saxifragus . The new combination to Petrorhagia saxifraga (L.) Link was published by Heinrich Friedrich Link . Another synonym for Petrorhagia saxifraga (L.) Link is Tunica saxifraga (L.) Scopoli . The specific epithet saxifraga means "rock breaking".
