Petroselinum is a genus of two parsley species of flowering plants in the family Apiaceae, native to western and southern Europe and northern Africa.

In the first year, they form a rosette of pinnate to tripinnate leaves and a tap root used as a food store over the winter.

In the second year they grow a flowering stem up to 1 m tall with sparser leaves and umbels of white or pinkish to yellowish-green flowers.

[2][3] The generic name comes from rendering the Greek word πετροσέλινον petroselinon "rock-celery" into Latin,[4][5] from πέτρα petra "rock, stone"[6] and σέλινον selinon "celery".

[7][1][3] Mycenaean Greek se-ri-no, in Linear B, is the earliest attested form of the word selinon.
