Giant hogweed is an extremely invasive plant, with infestations causing significant reductions in local biodiversity. Skin contact with the sap of giant hogweed can produce a nasty burn. A compound in the sap (furanocoumarins) reacts with light and skin to cause severe burns, blistering, and eventually dark scarring.
