A super-rare Amazonian cactus is set to flower for what is thought to be the first time ever in the UK - for 12 hours only.
The tropical Moonflower, or Selenicereus wittii, is usually exclusive to the floodplain rainforests of the Amazon Basin in South America.
However, Cambridge University Botanical Gardens (CUBG) has been home to one of these rare and exotic cactus plants since 2015.
