Latin is Ranunculus ficaria (fig like) verna (Spring like).
The native Lesser Celendine is back again in Bullbeggars Lane, pictures were taken last Monday 8th March 2021. The old lane (below) next to where I live is the perfect place for them to thrive in this semi shade damp environment and thrive they do as there are lots there. From the Buttercup family (Ranunculaceae), the flower is a good source of food for the bees in Spring – a friend has a few hives close to where I live. One of the old names for the plant is Pilewort because it was believed to be a cure for piles, apparently the roots are a visual representation of this.
