Sedum sarmentosum, commonly known as stringy stonecrop, is a succulent perennial.


Sedum sarmentosum was described by Alexander Andrejewitsch von Bunge. The name is considered as validly published.


Sedum sarmentosum is a species in the genus Sedum which contains approximately 395 to 759 species and belongs to the family of the Crassulaceae (Stonecrop Family). The type species of the genus is Sedum acre.



The perennials have a mat-forming habit and reach heights of 5 to 15 centimetres.


Sedum sarmentosum is evergreen. The moss-green, simple leaves are whorled. They are elliptic, entire and sessile. The leaves are around 5 centimetres large and have a glabrous surface.

Flowers and Fruits

Sedum sarmentosum produces cymes of ligth-yellow five-stellate flowers from April to June.

The perennials produce follicles.

Root System


Sedum sarmentosum is native to Japan, Korea, Manchuria and North China.


The perennials prefer a sunny situation on fresh to moist soil. The substrate should be gritty loam. They tolerate temperatures down to -18°C (USDA zone 7). Under glass use loamy potting compost with added gravel.

In summer the plants prefer good ventilation. Classification after Prof. Dr. Sieber

Pests and Diseases

Gnaw marks and slime trails indicate a problem with slugs. Prevent infestation by improving hygiene and by regularly working the soil. In case of an infestation use slug pellets or nematodes to control pest. Handpicking the slug also helps, do this preferably in the evening hours.

Damaged roots, withering, decolouration and dieback of leaves and shoots may be caused by stagnant moisture, fungi or bacteria. Remove affected plants. Prevent by improving hygiene and drainage.

Honeydew, galls and distorted leaves are a sign for an infestation with aphids. Use an insecticide or control biologically , e.g. with parasitic wasps or predators such as Aphidoletes aphidimyza.

Scale insects that sit on the undersides of the leaves and excrete honeydew can be controlled with insecticide or biologically with parasitic wasps.

Waxy fibres and honeydew on leaves and shoots indicate an infestation with mealybugs. Apply insecticide or control biologically with predatory ladybirds.

Small dark-coloured beetles feeding on the plants are very likely vine weevils. Their larvae feed on seedling, cuttings, roots and tubers. Handpick and destroy pests and improve hygiene. Additionaly use insecticide or biological control (nematodes).
