The Siracusa lemon (in Italian, Limone di Siracusa IGP) is the fruit of the cultivar "femminello" and its clones, corresponding to the botanical species Citrus x limon L. Burm. The femminello cultivar from Siracusa is the most common variety of lemon in Italy, and produces three main flowerings: the primofiore (from October 1st), the bianchetto (Also less commonly known as the maiolino.) (from April 15th) and the verdello (or summer lemon, from July 1st). 

The Siracusa lemon is characterised by a high juice content and abundance of oil glands in the skin, as well as the high quality of its essential oils. The Siracusan variety of lemon is called a femminello because of the fertility of the plant, which flowers all year round: the primofiore (literally, "first flower") matures from October 1st, has an elliptical shape, skin and flesh which varies from light green to lemon-yellow, and lemon-yellow juice; the bianchetto ripens from April 15th, is ovoid-elliptical, with light yellow skin, yellow flesh and lemon-yellow juice; the verdello matures from July 1st, is an spheroid elliptical shape, light green skin, and lemon-yellow flesh and juice.
