Botanists in Cambridge are waiting for the blooming of a rare and unusual cactus called the moonflower for the first time in the UK, according to The Guardian.
Experts say that the event is set to take place in a couple of days and will happen at sunset and be over by the time the sun rises the next day.
The event is also being live-streamed on YouTube so that the public can witness it too. Cambridge Botanists are hoping it will bloom annually, and that they are able to share it with other gardens.
