Rye (Secale cereale) is one of the main ingredients of bread and is mainly grown to make rye bread. In Ireland and the United States, rye is also used in the production of whiskey. Rye is mainly grown on sandy or cleared peat land and belongs to the grass family. It is an annual (summer rye) or biennial plant (winter rye). Winter rye needs a cool environment in order to bloom in May. Summer rye blooms later in the year. Rye still grows in the wild in central and eastern Turkey.
