Sempervivum 'Gamma'



A cultivar that colours very brightly in full sun. A hybrid between S. arachnoideum and S. tectorum raised by Georg Arends in Germany and introduced in 1929.

Horst Diehm said:

"medium-sized, deep brown rosettes, base greenish, silver hairy, flower pink, 10 cm" and went on to quote:
"listed in "Unsere Freilandtauden / Silva Tarouca" page 363, from 1934 excerpt: "the new Arend breeds, which emerged from arachnoidum - similar forms with large rosetted dark-leaved (circle of the tectorum), / "Gamma" rosettes in spring almost black-brown with white; valuable for the rock garden."

Erwin Geiger is quoted on Sempervivum List:

"In my opinion, the most beautiful Arend variety among the trio 'Alpha', 'Beta' and 'Gamma': Smaller to medium-sized, olive to emerald green rosettes that show black-red tones in spring. The leaves are white-ciliated, which gives the hybrid a nice contrast, especially in spring. The white tufts of hair at the tips of the leaves were inherited from its parent S. arachnoideum."

The AGS Encyclpedia online says:

"Medium-size hairy rosettes of olive green that change to a rich purplish-red in spring, but only holding this colour for a short time."
