Heracleum

Heracleum, the hogweeds, is a genus of about 60 species of biennial and perennial herbs in the Apiaceae (carrot family). They are found throughout the temperate northern hemisphere and high mountains as far south as Ethiopia.

• Heracleum mantegazzianum - Giant hogweed
• Heracleum sphondylium - Common hogweed
  • H. sphondylium subsp. montanum (syn. Heracleum maximum, H. lanatum) - Cow parsnip

H. mantegazzianum, a native of the Caucasus Mountains, grows to 4-5m tall, and can cause severe dermatitis if the sap gets on human skin. It has become a serious invasive weed in many areas of Europe and North America, after being introduced as a garden plant.
