Pirangi cashew tree
This famous tree near Natal, Brazil, is a 177-year-old cashew tree covering nearly 2 acres of ground. It was planted in 1888 by a fisherman who was unaware that the tree had a genetic mutation that would allow it to eventually take over so much space. When the branches of the Pirangi tree touch the ground, it puts down roots and keeps growing, unlike a typical cashew tree. Today the tree is a tourist attraction and park located a few hundred yards from the beach.
