Floating pennywort is a water-plant, growing in and/or out of still or slowly moving fresh water. Leaves are divided, but together make a half-circle (similar to a human kidney in appearance).
Growing rapidly, pennywort rapidly chokes waterways, forming mats that may need to be removed with earth-moving equipment (e.g. JCBs). At present, pennywort is currently restricted in distribution, principally in the southeast of England, but also northwest England and Wales: crucially, it is spreading quickly.
