Ten bright yellow Marsh-marigold flowers

Also known as ‘kingcups’, Marsh-marigold could be one of our most ancient plants. It is thought that it was growing here before the last Ice Age!

Marsh-marigold is a member of the buttercup family, a large, almost luxuriant version of its smaller cousin with bright yellow flowers and dark, shiny leaves. The latter are kidney shaped and quite waxy to touch – although doing so too often is best avoided: like all buttercups the marsh-marigold is poisonous and can irritate the skin.

Where to spot it

Marsh-marigold is widespread throughout Britain. It can be found in wet meadows, marshes and wet woodlands and grows well in shade.

How’s it doing?

Marsh-marigold is a common native species, whose distribution remains relatively stable in Britain. It is, however, locally threatened by drainage and agricultural improvement of its wet grassland habitat. Loss of habitat through drainage and abandonment is therefore one of the key threats to Marsh-marigold.

Did you know?

Marsh-marigold is also known as Mayflower – the name of the ship that carried the Pilgrim fathers to America. In Lancashire it is known as ‘the publican’ – maybe a reflection of its sturdy nature!
