Heracleum mantegazzianum, commonly known as giant hogweed, cartwheel-flower, giant cow parsnip, [4][5] hogsbane or giant cow parsley, is a plant in the family Apiaceae. In New Zealand, it is also sometimes called wild parsnip, or wild rhubarb. It typically grows to heights of 2 to 5.5 m (6 ft 7 in to 18 ft 1 in). Superficially, it resembles common hogweed (Heracleum sphondylium), Heracleum sosnowskyi, or garden angelica (Angelica archangelica). It is phototoxic and considered to be a noxious weed in many jurisdictions. 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 long-lasting scars. These serious reactions are due to the furocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant.
