Chui pen cao

Sedum sarmentosum, stringy or creeping stonecrop, is a low, mat-forming perennial succulent herb of the family Crassulaceae, native to eastern China, Korea, and Japan and widely naturalized in temperate gardens and disturbed sites elsewhere, including parts of North America. It produces slender, prostrate, fleshy stems that creep along the ground and root readily at the nodes, sending up short ascending flowering shoots only 5 to 15 cm tall. The leaves are sessile and arranged in whorls of three, narrowly oblanceolate to spatulate, succulent, bright green, and 1 to 2.5 cm long. Loose terminal cymes of small, bright yellow, five-petalled star-shaped flowers appear in early summer; fruit follicles contain numerous minute seeds. The entire fresh or dried aerial herb is used.
