Agave tequilana

Agave tequilana, commonly called blue agave (') 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. The tequila agave is native to the states of Jalisco, Colima, Nayarit and Aguascalientes in Mexico. The plant favors altitudes of more than 1500 m and grows in rich and sandy soils. Blue agave plants grow into large succulents, with spiky fleshy leaves, that can reach over 2 m in height. Blue agaves sprout a stalk (quiote) when about five years old that can grow an additional 5 m; they are topped with yellow flowers.Gentry, Howard Scott. Agaves of Continental North America.

The stalk is cut off from commercial plants so the plant will put more energy into the heart. The flowers are pollinated by the greater long-nosed bat, (also by insects and hummingbirds) and produce several thousand seeds per plant, many of them sterile. The plant then dies. The plants are then reproduced by planting the previously removed shoots; this has led to a considerable loss of genetic diversity in cultivated blue agave. It is rarely kept as a houseplant, but a 50-year-old blue agave in Boston grew a 30 ft stalk requiring a hole in the greenhouse roof and flowered in the summer of 2006.
