Description (by 't Hart & Bleij in IHSP 2003) :
Glabrous perennial herbs; sterile branches ± procumbent, rooting.
Leaves imbricate, linear-oblong, mucronate, terete, basally spurred, 10 - 15 mm, green or glaucous.
Inflorescences : Flowering branches erect or ascending, 15 - 40 cm, inflorescences terminal corymbs with 3 - 5 branches, densely glandular-pubescent, erect and flat-topped in bud, branches scarcely recurved, bracts leaf-like, glandular-pubescent.
Flowers (5 - to) 6 - to 8-merous, subsessile, sepals basally connate, equal, triangular, long acuminate, 5 - 7 mm, densely glandular-pubescent, petals free, oblong, cream-coloured or greenish-white, 8 - 10 mm, erect during anthesis, filaments white, glabrous, anthers yellow.
Cytology : 2n = 34, 68, 102
Ray Stephenson writes (Sedum, Cultivated Stonecrops, 1994, p. 121) : "Petals are very distinct as they remain upright. Pedicels, bracts, and huge sepals have glandular hairs. Budding inflorescences are erect, fruiting inflorescences are concave, and plants usually have a fairly creeping habit. Out of flower this species is indistinguishable from P. rupestre or P. montanum."
Plants from the W range are generally much smaller and shorter while in the Balkans plants are far more robust.
