Heracleum sphondylium, commonly known as hogweed, common hogweed or cow parsnip, is a herbaceous perennial or biennial plant, in the umbelliferous family Apiaceae that includes fennel, cow parsley, ground elder and giant hogweed. It is native to Europe and Asia. The common name eltrot may also be applied, but is not specific to this species. Umbelliferous plants are so named because of the umbrella-like arrangement of flowers they produce. The North American species Heracleum maximum (also called cow parsnip) is sometimes included as a subspecies of H. sphondylium.
The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative.
