    Why floating pennywort is a problem in Hounslow

    On Hounslow properties, floating pennywort grows up to twenty centimetres a day, choking ponds, ditches and slow water and blocking drainage and angling access. Hounslow sits in Greater London, where river corridors, railway embankments and post-industrial ground give invasive weeds like Japanese knotweed plenty of disturbed soil to colonise. Older housing with long gardens and vacant plots around the town see regular outbreaks, and infestations commonly spread along watercourses and disused rail lines into neighbouring streets.
