This is quite a common yellow composite and unusually it is easy to identify. It is quite small only reaching 15 cm tall at the most and has lemon yellow flowers. The distinctive feature is the long hairs on upper surface of the leaves which are supposed to make them look like a mouse's ear. As with P. aurantiaca (Fox-and-cubs) it reproduces by seed or vegetatively by stolons.

P. officinarum is found throughout the British Isles and Ireland.
