Sicily is the largest island in the Mediterranean Sea, and is home to dozens of endemic species and subspecies of plants, including the endemic genera Petagnaea and Siculosciadium. Although it is politically part of Italy, the World Geographical Scheme for Recording Plant Distributions treats Sicily as distinct botanical country together with neighboring islands and island groups including Malta (a sovereign country comprising two main islands, Malta and Gozo), the Aegadian Islands, Aeolian Islands, Lampedusa, Pantelleria, Pelagie Islands, and Ustica.
Plants are listed alphabetically by plant family. Extinct and presumed extinct species are indicated with †.
