According to the Guinness Book of World Records, the slowest-flowering plant is the rare species of giant bromeliad Puya raimondii, discovered at a height of 3,960 m (12,992 ft) in the Bolivian mountains in 1870. The flower cluster emerges after about 80-150 years of the plant's life (it produces an immense vertical stalk or panicle bearing numerous flowers). Once it has blossomed, the plant dies.
