In fact, the coffee plant is so common that it has its own name – coffee bush – and is often referred to as the ‘cuppa plant’ because it looks like a cup of coffee. The coffee bean is the largest plant in the world, growing to a height of up to 20 metres (65 feet) and reaching a weight of more than 1,000 kilograms (2,500 pounds).
It is also the second-largest living organism on the planet, after the elephant, with a body mass of about 2.5 tonnes (6.2 tons).
