"Heracleum sosnowskyi Sosnowsky's hogweed (""Heracleum sosnowskyi"") 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. 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 Mandenova in 1944. The species is named"

The common name giant hogweed usually refers to ""H. mantegazzianum"" alone but in some locales that common name refers to all three species as a group. The morphological similarity of species within the ""Heracleum"" genus and the difficulty of botanical identification has led to numerous synonyms and naming issues. For example, the classification of the species now widely known as ""H. maximum"" has been inconsistent. In the literature, the scientific names ""H. lanatum"", ""H."
