Chromaphyto said:Here are some pictures of Sempervivum calcareum that I photographed on the Rocher du Caire (altitude 777 m/2500 feet) above Remuzat, Drôme, France, July 14, 2014.
Rocher du Caire is known to be a popular area for watching Griffon vultures, they were successfully reintroduced a few years ago. This is a very accessible unique perspective by a small road. Just 15 minutes walk to get there
Tourists therefore look to the sky to see the vultures and I look at my feet to photograph what no one is looking at: beautiful groups of Sempervivum calcareum !
Panorama at the Rocher du Caire summit
We continue on a ridge to the mountain Le Devès (altitude 1048 m). The walk is very easy and rises gradually.
After 10 minutes, you begin to encounter groups of Sempervivum calcareum more dense along the ridge.
After a moment, there are thousands of Sempervivum, 10,000 .... 20,000 ... 30,000, I don't know !
Some groups of plants are green, others red. It depends on the food and water they have at their disposal.
