Heracleum sosnowskyi Manden., 1944 | |
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 of Eurasia and extends into the southern Caucasus region called Transcaucasia. The native ranges of Heracleum sosnowskyi and Heracleum mantegazzianum , a close relative, overlap in the Caucasus region. [1] Sosnowsky's hogweed is now a common weed in the Baltic States, Belarus, Russia, Ukraine, and Poland.
Early botanists considered H. sosnowskyi to be a subspecies of H. mantegazzianum. Sosnowski's hogweed was described as a separate species by Ida P. Mandenova in 1944. [1] The species is named in honor of the Russian botanist Dmitrii Ivanovich Sosnowsky (1885–1952), who found the species in Georgia in 1936. [2]
Heracleum sosnowskyi is 3–5 m (9.8–16 ft) in height, [3] with a straight, firm stem that can reach a diameter of 12 cm (4.7 in). [3] The leaves are 50–60 cm (20–24 in) long. The root is very firm, up to 30 cm (12 in) diameter. The inflorescence is a big umbel found at the end of every stem. It blooms during July through September and produces thousands of seeds. They are easily distributed by the wind, but especially by the water.
Sosnowsky's hogweed is a monocarpic perennial, [4] that is, after a mature plant flowers and produces seed, the entire plant including the root will die.
In the European Union, Sosnowsky's hogweed is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). [5] This implies that this species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the EU. [6]
All parts of H. sosnowskyi contain phototoxic furanocoumarins. [7] It is dangerous for humans because even small drops of the plant's juice cause skin photosensitivity and burns. [8] The plant is less dangerous for animals that have thick hair to protect them from the sun.
The plant was common only in the Caucasus area until it started to be used as a silage plant in other parts of the Soviet Union. As a result, it quickly spread in many areas of Russia, Belarus, and Ukraine. It is now a highly invasive plant in the Baltic States, Russia, Poland, and Belarus. [9] Many river valleys and roadsides host large stands of this weed. It is difficult to eradicate because the seeds remain viable for many years and the roots are difficult to remove. Herbicides are widely used in a fight against it, but the plant can later resprout from the roots. [10]
The plant is also used as a shield-hedge along the roads, preventing farm animals from escaping and wild animals from getting in. [3]
The decision to use the plant for silage was made in 1947 under Stalin's rule, so when the species later proved to be highly invasive and difficult to remove, people started to call it "Stalin's revenge". [11]
In February 2024, several lawmakers in the State Duma of Russia introduced a so-called "anti-hogweed bill" that would require property owners to remove the plant from their properties and impose a 50,000 ruble ($540) fine for individuals and 700,000 rubles ($7,550) for legal entities who fail to do so. [12]
Persicaria perfoliata is a species of flowering plant in the buckwheat family. Common names include mile-a-minute, devil's tail, giant climbing tearthumb, and Asiatic tearthumb. It is a trailing herbaceous annual vine with barbed stems and triangular leaves. It is native to most of temperate and tropical eastern Asia, occurring from eastern Russia and Japan in the north, and the range extending to the Philippines and India in the south.
Heracleum is a genus of biennial and perennial herbs in the carrot family Apiaceae. They are found throughout the temperate northern hemisphere and in high mountains as far south as Ethiopia. Common names for the genus or its species include hogweed and cow parsnip.
Heracleum maximum, commonly known as cow parsnip, is the only member of the genus Heracleum native to North America. It is also known as American cow-parsnip, Satan celery, Indian celery, Indian rhubarb, poison turnip or pushki.
Heracleum mantegazzianum, commonly known as giant hogweed, is a monocarpic perennial herbaceous plant in the carrot family Apiaceae.

Prosopis juliflora is a shrub or small tree in the family Fabaceae, a kind of mesquite. It is native to Mexico, South America and the Caribbean. It has become established as an invasive weed in Africa, Asia, Australia and elsewhere. It is a contributing factor to continuing transmission of malaria, especially during dry periods when sugar sources from native plants are largely unavailable to mosquitoes.
Anthriscus sylvestris, known as cow parsley, wild chervil, wild beaked parsley, Queen Anne's lace or keck, is a herbaceous biennial or short-lived perennial plant in the family Apiaceae (Umbelliferae), genus Anthriscus. It is also sometimes called mother-die, a name that is also applied to the common hawthorn. It is native to Europe, western Asia and northwestern Africa. It is related to other diverse members of Apiaceae, such as parsley, carrot, hemlock and hogweed. It is often confused with Daucus carota, another member of the Apiaceae also known as "Queen Anne's lace" or "wild carrot".
Heracleum sphondylium, commonly known as hogweed or common hogweed, is a herbaceous perennial plant in the carrot family Apiaceae, which includes fennel, cow parsley, ground elder and giant hogweed. It is native to most of Europe, western Asia and northern Africa, but is introduced in North America and elsewhere. Other common names include cow parsnip or eltrot. The flowers provide a great deal of nectar for pollinators.
Phytophotodermatitis, also known as berloque dermatitis, margarita photodermatitis, lime disease or lime phytodermatitis is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent followed by exposure to ultraviolet A (UV-A) light. Symptoms include erythema, edema, blisters, and delayed hyperpigmentation. Heat and moisture tend to exacerbate the reaction.
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.
