Agave tequilana, commonly called blue agave (agave azul) or tequila agave, is an agave plant that is an important economic product of Jalisco, Mexico, due to its role as the base ingredient of tequila, a popular distilled beverage. The high production of sugars named agavins, mostly fructose, in the core of the plant is the main characteristic that makes it suitable for the preparation of alcoholic beverages. It is rarely kept as a houseplant, but a 50-year-old blue agave in Boston grew a 30-foot (9 m) stalk requiring a hole in the greenhouse roof and flowered in the summer of 2006.
