Primula veris, commonly called cowslip, is a clump-forming, herbaceous (sometimes semi-evergreen) perennial of the primrose family that is noted for its early to mid-spring bloom of showy, nodding, lemon yellow flowers. It is native to temperate areas of Europe and Asia.
Grow Primula veris in moist soil in partial shade. It’s best grown in groups, especially if naturalised in grass, such as around the edge of a pond. Let plants self-seed after flowering, and mulch annually with well-rotted manure or compost.
