A super-rare Amazonian cactus has flowered for what experts believe is the first time ever in the UK – but it has already started to wither.
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.
Yesterday, for the first time, it flowered after a bud grew from the bizarre-looking plant.
But it happens just once, and only for around 12 hours, and it has already started to close up again.
It was thought the plant would blossom at night, but a garden spokesperson said it appeared it was a ‘sun lover’.

Thousands of people from around the world have been eagerly awaiting its bloom via a YouTube livestream.
A spokesperson for the gardens said: ‘It appears that our moonflower is a bit of a sunlover and it has started opening during the day, just to keep us all on our toes!
‘Oh it’s been worth the wait – what a beauty!’
The strange-looking bud measures an impressive 27cm and is covered with tufts of ‘hair’ whilst closed.

It appears as if it is growing straight out of the trunk of another tree in the CUBG Tropical Glasshouse, but in reality, the Moonflower is an epiphyte – meaning it relies on another plant as an anchor point.
At CUBG, the cactus’ strange, flattened, leaf-like stem has wound its way around a Water Chestnut tree.
Alex Summers, Glasshouse Supervisor at CUBG, who is responsible for growing and nurturing the Moonflower, said: ‘I noticed the flattened stems, or pads, which swirl around the trunk of our Water Chestnut had sent out a flowerbud in late November.
‘This was a lucky spot as it’s almost 12 feet up in the air and could have so easily been missed.’

This sweet smell attracts the night-flying hawkmoth – which is believed to be the only insect able to pollinate the Moonflower, due to their extremely long tongues.
Two hours after flowering begins, the plant changes its scent to something far less pleasant, and the flowering is usually over by sunrise.
Alex is planning to hand-pollinate it, with the hope of producing seed.
