Under the Environmental Protection Act 1990, giant hogweed is also classified as controlled waste. The photo shows a plant growing on an allotment. Bags have been put over the seedheads to prevent the seeds spreading while the plant is dying from the effects of the herbicide it has been sprayed with.
