It seems like many Agave species have the common name of century plant, somewhat implying that the plants live for a hundred years. While it is indeed long-lived, a few decades is more the norm for this monocarpic species; it can take thirty years or more to flower, but upon eventual production of fruit, the entire plant begins to senesce.
More photographs of Agave americana are available from the Master Gardeners of the University of Arizona Pima County Coop Extension. The Plants for a Future database has details on the edible, medicinal and textile uses of this species.
