Nicotiana tabacum is an annually grown herbaceous plant and the most commercially important species in the genus Nicotiana. Plants grow 1-2 meters tall with thick, minimally branched stems and large ovate to elliptical leaves that can exceed 50 cm in length. Originally from the Americas, tobacco is cultivated worldwide primarily for its cured leaf. The plant is also a foundational model organism in plant biology — the Hoagland nutrient solution was originally developed using tobacco. Tobacco is a heavy feeder with a uniquely high potassium demand (K:N accumulation ratio of 2:1) and is extremely sensitive to chloride.
