Sedum angustifolium, in its protologue (in Z. B. Hu et al., Acta Phytotax Sin. 19: 311. 1981), was separated from S. sarmentosum primarily by having narrower leaves and a different chemical profile, but the described morphology falls within the range of the latter species as recognized here.

Sedum sarmentosum is used medicinally, as an ornamental, and sometimes as a vegetable.
