What is the Largest Weed in the World?


The giant hogweed (Heracleum mantegazzianum), originally from the Caucasus, reaches 3.65 m (12 ft) in height and has leaves 91 cm (36 in) long. It was introduced into Europe, Canada, and the US as a garden ornamental and – after taking hold as a pest – has since become naturalized in these parts of the world.
