Tequila Agave, Century Plant. 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, mostly fructose, in the core of the plant is the main characteristic that makes it suitable for the preparation of alcoholic beverages. Great addition to cactus - rock gardens - ethno-botanical collections. Drought-tolerant; suitable for xeriscaping. Grows fairly fast in summer if provided with extra water.
