Sempervivum 'Cmirals Yellow'



More accurately, Sempervivum montanum ssp. carpaticum 'Cmirals Yellow'. The most spectacuarly yellow of a small group of yellow rosetted cultivars. Unfortunately it also seems to be the most feeble, it wimps along and will drop dead if given a suitable opportunity. Too much water, too much sun or insufficient nervous angst seem to be enough to carry it away. Still, I am inordinately fond of it. There are some new gold foliaged plants in the "Chick Charms" series raised by Chris Hanson that may be stronger growers.

Erwin Geiger is quoted on Sempervivum List:

"This sensational local form of S. montanum ssp. carpathicum was found by Otokar Cmiral from the Czech Republic in the Low Tatras and propagated in culture. In spring, the rosettes are almost completely yellow in full sun and nutrient-poor soil! This coloration is unique and only yellow or yellow-green seedlings are known from S. heuffelii."









World of Succulents says:

"This succulent was Found by Otokar Cmiral (CZ) in 1979 in the valley of the Low Tatras mountains in central Slovakia in a group of the normal green form of Sempervivum montanum subsp. carpathicum.
Sempervivum montanum subsp. carpathicum 'Cmiral's Yellow', also known as Sempervivum 'Cmiral's Yellow', is a small succulent that forms beautiful rosettes of leaves that vary in color from dark green and light green to yellow-orange. The rosettes can reach up to 1.6 inches (4 cm) in diameter and produce offsets on short stolons. The leaves are thick, fleshy, hairy, and broadest near the tip. The color of the leaves changes depending on the season and growing conditions."
