Heracleum is a genus of flowering plants in the family Apiaceae, commonly known as giant hogweed. These plants are characterized by their large, umbrella-like clusters of white flowers and can grow up to 14 feet tall. They are native to Europe and Asia but have spread to other regions, including parts of North America. Giant hogweed is known for its invasive nature and can pose health risks due to its sap, which can cause severe skin burns when exposed to sunlight. Management of Heracleum species often involves physical removal and public awareness to prevent their spread in non-native areas.
