Marsh Marigolds are one of our most ancient flowers, believed to have been growing here since before the last Ice age and to have survived that ice age and flourished in the melting waters. The last Ice age ran from about 110,000 years ago until 12,000 years ago, it was a long winter and this is an old flower.
It is found all over the UK and is native to much of the Northern Hemisphere including North America and Canada. It does well in cold climates.
In the UK it flowers in February and can last until April.
This next picture shows the typical habitat, showing young plants growing alongside and through a woodland stream. This picture was taken on the 27th of February 2014.
Marsh Marigold is a member of the Buttercup family and I have heard it said that it is easily confused with other buttercups and even Lesser Celandine. They are all related and yellow but the Marsh Marigold flower is twice the size of any of the others, about two inches across it has quite dense and luxuriant foliage and it grows in water. There is really nothing that you can confuse it with.
Species: Caltha palustris
