Primula veris

Primula veris  is a flowering plant in the genus Primula. The species is native throughout most of temperate Europe and Asia, and although absent from more northerly areas including much of northwest Scotland, it reappears in northernmost Sutherland and Orkney.
It is a low growing herbaceous perennial plant with a rosette of leaves 5-15 cm long and 2-6 cm broad. The deep yellow flowers are produced in the spring between April and May; they are in clusters of 10-30 together on a single stem 5-20 cm tall, each flower 9-15 mm broad. Red-flowered plants do occur, very rarely.
