Heracleum Mantegazzianum
''Heracleum mantegazzianum'', commonly known as giant hogweed, is a monocarpic perennial herbaceous plant in the carrot family Apiaceae. ''H. mantegazzianum'' is also known as cartwheel-flower, giant cow parsley, giant cow parsnip, or hogsbane. In New Zealand, it is also sometimes called wild parsnip (not to be confused with ''Pastinaca sativa'') or wild rhubarb. Giant hogweed is native to the western Caucasus region of Eurasia. It was introduced to Britain as an ornamental plant in the 19th century, and has also spread to other areas in Western Europe, the United States, and Canada. Its close relatives, Heracleum sosnowskyi, Sosnowsky's hogweed and Persian hogweed, have similarly spread to other parts of Europe. The sap of giant hogweed is Phototoxicity, phototoxic and causes phytophotodermatitis in humans, resulting in blisters and scars. These serious reactions are due to the furanocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant. Consequ ...

Heracleum Persicum
''Heracleum persicum'', commonly known as Persian hogweed or by its native name ''golpar'' (), is a species of hogweed, a perennial herbaceous plant in the carrot family Apiaceae.

It is now very common in northern Norway, where one of its names is Tromsø palm (after the city of Tromsø). The plant has also been spotted in Sweden. In Finland, it has been declared an invasive species. Persian hogweed is a polycarpic perennial, that is, a mature plant flowers and bears fruit season after season. Invasiveness status In Europe, Persian hogweed is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the European Union.

Heracleum Sosnowskyi
''Heracleum sosnowskyi'', or Sosnowsky's hogweed, is a monocarpic perennial herbaceous flowering plant in the carrot family Apiaceae. Its native range includes the central and eastern Caucasus regions and Transcaucasia. The native ranges of ''Heracleum sosnowskyi'' and '' H. mantegazzianum'', a close relative, overlap in the Caucasus region. Sosnowsky's hogweed is now a common weed in the Baltic States, Belarus, Poland, Russia, and Ukraine. Description ''Heracleum sosnowskyi'' is in height, with a straight, firm stem that can reach a diameter of . The leaves are long. The root is very firm, up to diameter. The inflorescence is a big umbel found at the end of every stem. It blooms from July to September and produces thousands of seeds, which are easily distributed by wind, but especially by water. As Sosnowsky's hogweed is a monocarpic perennial species, the entire plant (including the root) dies after flowering and producing seed. Similar species Similarly tall invasi ...
