Description: Sedum spurium is a vigorous, fast-spreading, mat-forming herbaceous succulent perennial native to the Caucasus Mountains. It produces numerous creeping, rooting stems up to 15 cm long and forms dense mats from 30-70 cm or more in diameter and 7.5 cm tall. Plants bear rounded evergreen leaves topped by rounded clusters of starry red, pink or white flowers in late summer. Like all those of the same genus, the the flowers of S. spurium have 5 petals and 5 stamens. It is a variable species in respect to size and dentation of the leaves and flower colour. It is widely cultivated and a number of cultivars are available. In flower this sedum is one of the most rewarding dwarf plants in cultivation.
Sterile stems: Procumbent or creeping, rooting, glabrous or somewhat papillose, 5-15 cm long often purple-tinted.
Leaves: Opposite or rarely alternate, grouped in rosettes, simple, sessile or shortly petiolate, spatulate to obovate or orbicular, base wedge-shaped, usually crenate (slightly toothed in the upper half, or whole), 15-35 mm long, 10-12 mm wide dark green to blue-grey with a gloss, often purple-tinted.
Inflorescence: Held on procumbent or ascending flowering branches up to 10-30 cm long and papillose. The inflorescence is a rather dense corymb with 3-5 branched cymes (terminal inflorescences) and 15-30 flowers. The bracts are oblanceolate to oblong, papillose.
Flowers: Small star-shaped, 5-merous (rarely 6-merous), subsessile or with short pedicels. Sepals deltoid-lanceolate, obtuse to acute, papillose towards tip, to 10 mm long. Petals erect in the lower part and usually spreading above, subovate, short- or sometimes long-mucronate, with slightly recurved tips, carinate, 7 - 12 mm long, pure white, pink or even crimson. Filaments 5-9 mm long. Anth red. Nectarie 0.5 x 1 mm.
Fruits: Fused at base, (sub-) erect, glabrous, 5-9 mm long.
Chromosome number: 2n = 28, 42.
