Giant hogweed is native to the Caucasus region and Central Asia. It was introduced to Britain as an ornamental plant in the 19th century, and it has also spread to many other parts of Europe, the United States, and Canada.
The sap of giant hogweed causes phytophotodermatitis in humans, resulting in blisters and scars. These serious reactions are due to the furocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant
Don’t use a weed whacker as it can splash the toxic sap onto your skin.
