Yareta, The 3,000 Years Old Plant

These rocks on the highlands of the Andes looks like they are covered with moss. Actually, they are a type of flowing plant known as Yareta and it lives in colonies which can be thousands of years old.
Yareta is a flowering plant that grows in the cold Puna grasslands of the Andes in Peru, Bolivia, northern Chile, and western Argentina. To survive the extreme conditions, Yareta grows in packs so dense that its stems can take the weight of a human. The plant keeps close to the ground in order to retain as much heat in as possible.
