About

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 (not to be confused with Heracleum maximum of North America). The flowers provide a great deal of nectar for pollinators.

Where it grows

Heracleum sphondylium is native to most of Europe, western Asia and northern Africa. For example, it occurs in southern and southwestern Poland but much less so in other parts of the country. The species has been introduced into North America. In particular, it has been introduced to eastern Canada, but reports of H. sphondylium in Canada are rare. Some authorities claim that Heracleum sphondylium subsp. sibiricum (a synonym of Heracleum sibiricum) has been introduced in the United States, but in New England, botanists have been unable to identify the taxon to subspecies rank.

Uses

Borscht derives from an ancient soup originally cooked from pickled stems, leaves and umbels of common hogweed. The young shoots are considered excellent eating by many foragers.
