Sempervivum

ALTUM (Turrill)

This species was first collected by Dr. P.L. Giuseppi on Mount Armchi in the Caucasus in 1935. The original description was published in 1936 in the Bull. Soc. Bot. Bulg. Vol. 7 page 124. Rather lax rosettes 2,5 to 4 cm in diameter with light green glandular pubescent leaves on upper and lower surfaces. On exposure the outer leaves develop red tips. The flowers are red-purple having yellow anthers. Offsets are produced on stolons 8 to 12 cm long. Not one of the easiest species under cultivation as it dislikes winter damp.
