Sedum

Sedum (Sedum ), also called stonecrop, form a genus of flowering plants in the family Crassulaceae ( Crassulaceae ). The botanical name of the genus Sedum is derived from a Latin common name for several species of the Crassulaceae. With about 420 species, it is the largest genus in the family Crassulaceae.

Features

Sedum species are annual or perennial herbaceous plants, rarely subshrubs that are more or less succulent. Especially the fleshy leaves store water. The leaf margins are usually smooth. Stipules absent.

The inflorescences are constructed differently. The most hermaphrodite, rarely unisexual flowers are usually fünfzählig, rarely three to neunzählig. The sepals are usually grown free or rarely at the base. The five most predominantly yellow, rarely white or pinkish petals are usually free or almost free. There are usually two circles of stamens present. The carpels are free or fused at their base.

Are formed follicles. The seeds are small.

Physiology

Most species of sedum plants are CAM.

Systematics and distribution

The genus Sedum is mainly distributed in the subtropical and temperate zones of the northern hemisphere. However, some species are native to Central and East Africa and South America. The greatest diversity of species is found in North America ( about 170 species), followed by Asia ( about 130 to 140 species ). The remaining approximately one hundred species spread across Europe, the Middle East, Africa and the Atlantic islands.

The first description was in 1753 by Linnaeus in Species Plantarum. After Henk 't Hart (1944-2000) and Bert Bleij subdivides the genus Sedum in two subgenera with the following types:
