Brassica cretica

Brassica cretica is a species of flowering plant in the family Brassicaceae, native to the Eastern Mediterranean, particularly to Greece and the Aegean Islands. It was first described by Jean-Baptiste Lamarck in 1785. A 2021 study suggested that it was the origin of cultivated Brassica oleracea, with later admixture from other Brassica species.
