Agave cactus can live for many years, with some species living for over 50 years. The average lifespan of an agave cactus is around 20 years. Some agave cacti have been known to live for over 100 years, however this is rare. Agave cacti are native to the desert regions of Mexico and the southwestern United States. They are adapted to surviving in hot, dry conditions and can often be found growing in arid, rocky areas. Agave cacti have thick, fleshy leaves that store water, allowing them to survive for long periods without water. The flowers of the agave cactus are typically yellow or green and bloom during the summer months. After the flowers die back, the plant produces a large, fleshy fruit that is edible. Agave cacti are not typically grown as houseplants, as they require very specific growing conditions. However, they can be successfully grown in containers outdoors in areas with warm weather and plenty of sunlight.
