You may avoid it but can you say the same for children encountering it elsewhere when it spreads beyond your property? I'm just glad you're not one of my neighbours. The Wildlife and Countryside Act 1981 (as amended) lists it on Schedule 9, Section 14 meaning it is an offence to cause giant hogweed to grow in the wild in England and Wales (similar legislation applies in Scotland and Northern Ireland). In 2013 the UK government decreed that anyone failing to control Giant Hogweed (and other invasive weeds) could receive an anti-social behaviour order. It will be seen as committing a criminal offence. For an individual on-the-spot penalties of £100 can be issued, if prosecuted fines of up to £2,500 and companies up to £20,000.
