Tulipa gesneriana, the Didier's tulip or garden tulip, is a species of plants in the lily family, cultivated as an ornamental in many countries because of its large, showy flowers. Its region of origin is not entirely certain, but the species is widely believed to have originated in Turkey, as is the case with many species of tulips that came into Europe from the Ottoman Empire. It has become naturalised in parts of central and southern Europe and scattered locations in North America. Most of the cultivated forms of tulip are derived from Tulipa gesneriana.
