In the lessons

In outdoor safety lessons, giant hogweed is a dangerous plant: it can grow taller than an adult, with a thick green stem with purple blotches and huge leaves. Do not touch it; if sap gets on your skin, cover it from the sun, wash it with soap and water, and tell an adult. It grows by rivers, roadsides and parks in the UK, Ireland and North America. Phrases: «giant hogweed», «common hogweed», «hogweed burns».
