Sempervivum Nevadan ( synonymous with S. minutum) has great variability in their populations, so that we can find very different copies each. The origin of this species, presumably due to crossovers and hybrids have not yet stabilized, as might be inferred by its high chromosome number. Although as always, all are hypotheses. Their size ranges between 2 and 3 cm in diameter.
At first, it was discovered S. Nevadan in Sierra Nevada and later was discovered in the nearby Sierra de Baza. Sempervivum although both belong to the same species, the two populations have very different characteristics.

populations Sierra Nevada, are found above 2,500 m. altitude in abundance. Grow in schistose rocks and outer leaves recurve as to protect the center of the plant from excessive sunlight and also stained a magenta color characteristic. The pink flower is very intense.
populations Sierra de Baza, a little more northern, are at a maximum altitude of 2213 m. grows on limestone rocks. Populations are more uniform than those of Sierra Nevada and some more size. Its leaves are somewhat tomentum and do not have the red hue with intense sunlight. The flowers are a lighter pink, and faded and sometimes almost white.

So Sempervivum is extremely variable, we find clones with abundant pilosity and instead almost no other, with all the intermediate types possible. Here are three of my clones from different localities:
hirtella Form:
In September
In November 
This is no particular form:
S. Nevadan of Laguna del Caballo (Sierra Nevada)
