Also called ‘Cursed Buttercup’, ‘Blister Buttercup’, and ‘Marsh Crowfoot’, amongst other names, this wetland loving annual herb has very small bright yellow flowers. It has distinctive small thimble-shaped fruit and glossy palmately lobed leaves which are hairless.
The foliage of this plant is more toxic than most Ranunculus, and during earlier times beggars used to smear the juices of the leaves on their arms and faces to create blisters to try to solicit favours or fortune in sympathy.
It flowers May to September, and is found growing out of the water in marshes, ditches, ponds and lake margins, wet tracks, and woodland rides. Common and widespread.
