The Comba di Vertosan is a interesting place of Aosta Valley. The Sempervivum montanum that are growing in this place, between 1600 and 2180 mt, are very, very large. From 3.5 cm up to 11 cm. Further 2180 mt, the montanum are 2 cm large. The question is: are they subsp montanum or subsp. burnatii? I think subsp. montanum.
Greg, in Vertosan, there is, at 1800 mt height, a nice restaurant.
