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 10-30 cm tall, each flower 9-15 mm broad.

It may be confused with the closely related Primula veris (cowslip) which has a similar general appearance although the oxlip has larger, pale yellow flowers more like a primrose, and a corolla tube without folds.
