The giant hogweed is a plant known for its height, commonly growing to 2 to 5 metres (roughly 6 to 15 feet). This plant is also characterised by its hollow stems with ridges/bristles and dark purple spots. It is native to Central Asia, and has spread to various countries of Europe, the US, and Canada.

Sap from the giant hogweed is dangerous to humans, causing phytophotodermatitiis, or severe skin blister and inflammations. If the sap gets into the eyes, temporary or permanent damage can ensue, including blindness.
