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. One planted near sea level at the University of California's Botanical Garden, Berkeley, USA in 1958 grew to 7.6 m (24 ft 11 in) and bloomed as early as August 1986 after only 28 years.
