Description (according to Praeger, An Account of the Sempervivum Group, 1932) :

"A robust decumbent downy perennial.

Stem stout, branched more or less horizontally, giving rise to a loose tuft.

Rosettes about 16 - 20 cm across, flattish, rather dense.

Leaves imbricate, oblanceolate or oblanceolate-spathulate, acute, apiculate, 8 - 10 x 2 - 3 cm, attenuate at base, ciliate with distant strong tapering cilia alternating with numerous very fine ones only half as long, green or greyish-green, covered on both sides with fine pubescence, under side with many dark green longitudinal linear glands.

Flowering shoots lateral, arising from the lower leaf-axils, ascending, 30 - 45 cm long, pubescent, leafy with small oblong or linear leaves much resembling those of caespitosum [simsii], diminishing upwards.

Inflorescence a rather compact corymbose cyme 8 - 25 cm across, of semi-erect alternate branches dichotomous in upper part.

Flowers : Buds ovate or broadly conical, flowers flat, 8-9-parted, 8 mm across, bright yellow, on pubescent pedicels 2 - 4 mm long, calyx bowl-shaped, pubescent, 4 mm long, cut half-way down into landeolate acute segments, petals lanceolate, acute, 7 mm long, glabrous, bright yellow.

Flowering time : Spring.

N.E.Brown described this plant from garden material in 1901. He considered that it was a good species. .... It has never been found wild .... and I have no doubt it is a garden hybrid..... Origin unknown."
