This is a plant which used to be common but is now much less so. It is found typically in wet areas near old ponds but doesn't usually find its way to new wet habitats very quickly.

There is plenty of this plant in England particularly in the south but very little in Scotland, small amounts in Ireland and Wales. It is now classified as Vulnerable which means that during the last decade or so numbers have been decreasing.
