The great sedum plant ( Hylotelephium telephium (L.) H. Ohba , Syn .: Sedum telephium L. ) is a species of the genus Hylotelephium in the family of thick-leaf plants (Crassulaceae). The great sedum plant is a collective species , i.e. the amalgamation of several previously individually described, closely related small species. The species occurs in almost all of Europe and grows mainly on dry locations such as walls, rocks, dry forests or fields.

description

The great sedum plant is a succulent perennial that reaches heights of 25 to 50 cm, has an upright, bare stem and thick, beet-shaped rhizomes . The leaves are oblong-ovate and unevenly serrated.

The greenish to yellow or purple flowers appear in July to September. In autumn, the above-ground parts of the plant die off, while the thickened roots and hibernating buds survive and allow them to sprout quickly in spring.

The species has chromosome numbers 2n = 24, 36 or 48.

The hover fly Cheilosia semifasciata is a leaf miner of the great sedum plant.
