On a stretch of coastline in northeastern Brazil, in a small beach town called Pirangi do Norte, there is something that looks from the ground like a dense, sprawling forest. Visitors walk through it on suspended walkways, surrounded by what appears to be dozens of tree trunks and a canopy so wide it covers an area the size of more than a football field. But it is not a forest. It is one single cashew tree.
The tree is known as the Cajueiro de Pirangi, which means the Cashew Tree of Pirangi, and it has been recognised as the largest cashew tree on Earth since 1994. It covers roughly 8,500 square meters, which is about 91,500 square feet, and its branches spread out to a circumference of around 500 meters. To put that in perspective, it is the size of roughly seventy normal cashew trees, all fused into one organism.
The secret behind this impossible size is a genetic mutation. Most cashew trees grow upward, with branches reaching for the sky. But this tree has a condition called plagiotropism, which causes its branches to grow sideways instead. As the branches grow longer and heavier, they bend toward the ground until they touch the sandy soil. When that happens, they put down new roots, creating what botanists call adventitious roots. These new roots act like secondary trunks, supporting the ever-expanding canopy while remaining physically connected to the original tree.
Out of the tree's five main branches, four have followed this pattern, rooting themselves repeatedly and spreading outward decade after decade. The fifth branch behaves normally and stopped growing once it reached the ground. Locals have given it a nickname. They call it Salario Minimo, which means minimum wage, because it is the only part of the tree that actually works a normal job.
The tree is also remarkably productive. Despite its unusual shape, it still bears fruit every year. During the harvest season, which typically runs from November to January, it produces between 60,000 and 80,000 cashew fruits, amounting to up to 2.5 tonnes in a good year. That is not a typo. One tree, tens of thousands of cashews.
The origins of the tree are debated. Local legend says it was planted in December 1888 by a fisherman named Luis Inacio de Oliveira, who reportedly died in its shade at the age of ninety-three. Another version attributes the planting to a former mayor of Natal who owned the land. Some researchers have even suggested the tree could be older than a thousand years based on its growth characteristics, though records list it as over a hundred years old.
What is not in dispute is the impact the tree has on the region. It draws hundreds of thousands of visitors every year. In 2024 alone, more than 350,000 tourists came to see it. Local authorities have built elevated walkways to protect the tree's extensive root system from being trampled. There is a viewing platform where you can look out over the canopy and truly understand its scale. And in 2025, the tree was officially recognised as natural, historical, and touristic heritage of the state of Rio Grande do Norte.
The tree is still growing, which has created some challenges. Its branches have pushed against the boundaries of its park and now extend over a public road. In 2012, a supporting structure had to be installed to hold up branches that had grown too far. A recent court decision even ordered pruning for the first time in the tree's documented history, something that had never been done before.
There is something wonderful about a single living thing that refuses to follow the rules. It does not grow up. It grows out. It does not stand alone. It roots itself again and again. And in doing so, it becomes something that looks like a forest but is actually one quiet, patient, deeply stubborn tree.
