🌿 Yareta — The 3,000-Year-Old Plant
At first glance, these incredible green formations high in the Andes Mountains look like rocks completely covered in moss. But they’re actually something much more fascinating.
This is Yareta (Azorella compacta), also known as Llareta—a flowering plant that grows in the harsh highlands of Peru, Bolivia, northern Chile, and western Argentina at elevations of roughly 3,200–4,500 meters (10,500–14,800 feet).
To survive the freezing temperatures and relentless winds, Yareta grows into incredibly dense, compact colonies that hug the ground. These formations can become so solid that they’re capable of supporting the weight of a person. Its tightly packed growth helps trap heat and protect it from powerful mountain winds, while its waxy leaves help reduce moisture loss.
But the most incredible thing about Yareta is how slowly it grows—only about 1.5 centimeters per year.
Because of this extremely slow growth, some of the massive Yareta colonies covering the rocks of the Andes are estimated to be more than 3,000 years old.
Imagine looking at a living plant that began growing more than a thousand years before the Roman Empire. 🤯🌿
