Winter Hardiness of Sedum

Sedum L.

The winter hardiness of Sedum is determined by their species-specific adaptation to climatic zones and their resistance to winter damping-off under conditions of moisture stagnation. Important evaluation criteria include the retention of ornamental value in spring and the ability of shoots to regen…

In the reference 7 varieties crop Ice Plant, where this is mentioned in the description.

Species adapted to temperate climates, such as Sedum acre, S. album, S. reflexum, S. spectabile, and S. spurium, are characterized by high winter hardiness and are capable of withstanding frosts down to -40 °C without protection. In contrast, species of Mediterranean or Mexican origin, including Sedum lydium, S. hispanicum, S. sieboldii, and S. pachyphyllum, require protection, as they are less resistant to harsh snowless winters and excessive moisture.

A critical factor for the survival of Sedum during the cold period is not only the absolute temperature but also soil moisture. Stagnation of moisture in winter provokes root rot and plant loss, so the presence of drainage is a necessary condition for winter hardiness. Agronomic practices also influence the ability to survive winter: excessive fertilization reduces frost resistance, while regular rejuvenation of plantings through division or cuttings maintains their overall vitality.
