Sempervivum

ARMENUM

A rare species first described and named in 1856. Not known under cultivation until introduced by E. K. Balls in 1934 from Gumush Hane in northern Turkey; reference in Quart.Bull. Alp. Gard. Soc. Vol. 10 page 233 (1942). Note that in this reference the plant collected from Vavuk Dagh, to quote: ‘provisionally identified with S. armenum’, is now S. glabrifolium; Ref., R.B.G.E. Vol. 29 No. 1 (Jan. 1969).

S. armenum has rosettes 4 to 6 cm in diameter, in appearance similar to some forms of S. tectorum (Linn). Rosette leaves green, glabrous, ciliate, with dark purple apex. Stolons are few, and the young rosettes, glandular at first, soon becoming glabrous. Flowers greenish-yellow with purple base, filaments purple with yellow anthers. A slow-growing species that is apt to damp off with the winter wet.
