Why giant hogweed is a problem in Penarth
On Penarth properties, giant hogweed sap causes severe phototoxic burns and long-term light sensitivity, which makes it a genuine safety issue on footpaths, riverbanks and school boundaries. Penarth's Victorian seafront and Cardiff Bay interface sit on disturbed reclamation ground, and the old Penarth dock and railway siding beds remain a recurring source of knotweed along the foreshore.
