Rye

(species Secale cereale), cereal grass and its edible grain that is used to make rye bread and rye whiskey. The plant grows to a height of 1 to 2 m (4 to 6 feet) and has spikes composed of two or more spikelets bearing florets that develop one-seeded fruits, or grains. Rye cultivation probably originated in southwestern Asia about 6500 BC, migrating westward across the Balkan Peninsula
