The plant, called the Puya chilensis, is covered with razor-sharp spines and has a 10-foot tall flower spike. It's been growing in the Royal Horticultural Society at Wisley for 15 years now.
In the Andes it uses its sharp spines to snare and trap sheep and other animals, which slowly starve to death.
The animals then decay at the base of the plant, acting as a fertiliser.
As you might expect, the plant grown in the UK was not fertilized with the rotting flesh of a sheep, or any other animals.
"It's growing in the arid section of our glasshouse with its deadly spines well out of reach of both children and sheep alike."
