    Why floating pennywort is a problem in Ystalyfera

    On Ystalyfera properties, floating pennywort grows up to twenty centimetres a day, choking ponds, ditches and slow water and blocking drainage and angling access. Ystalyfera is in the upper Swansea Valley, where steep ground, the Swansea Canal and old works land hold invasive weeds.
