The traditional practice of collecting wild edible plants is still active especially in small communities and has a great interest today at the scientific and cultural level. The revaluation of wild plants is of considerable importance not only for nutrition, but also to meet the "desire for nature", which appears increasingly marked, especially in large cities. This research on Sardinian food plants takes into account the existing literature from the first mentions by Greek and Latin authors and the ancient medieval Condaghes, a kind of ecclesiastical register of businesses, in the early centuries of the second millennium. In times closer to us, thanks to Fara, Manca dell'Arca, Moris we have important information about the use of cultivated and wild plants in the past. Especially at the end of the last century and in recent years, a large amount of very detailed data on the use of plants in the whole of Sardinia, offers the opportunity to attempt a synthesis of this field. 223 species are considered according to the parts used (bulbs, rhizomes, tubers, tuberous roots, basal leaves, stems, inflorescences, flowers, fruits, seeds, biological forms). In addition, a local name for each species is seleced. Of the 41 plant families included, the most important are: Asteraceae, Rosaceae, Brassicaceae, Phaseolaceae, Liliaceae (including Alliaceae, Asparagaceae, Asphodelaceae, Ruscaeae), Apiaceae and Lamiaceae. The grasses (annuals and perennials) constitute 57% of the total. The richness of local names and their variants has a great cultural significance that ranges from plant geography to systematics, ethnography to history and human migration, plant names to the evolution of languages, the domestication of plants to the regional cuisine and to the traditional medicine of a region. That is why food plants of Sardinia are a distinctive cultural heritage of this region, but strictly linked to the common history of the Mediterranean countries.
