As a group, the Agavaceae are clearly related to the Hostaceae. The Agavaceae are economically important for a number of reasons. Many species of Agave are cultivated as ornamental succulents especially in warm, temperate gardens in developed nations. In less developed areas, the same plants are often cultivated for fencing. Soup can be obtained from the rhizomes, paper can be made from the leaves, and the flowers can be cooked.
Several species are a source of fiber.
Perhaps the best known product is tequila or mescal, a strong drink. Even the sap can be fermented. The large, basal rosettes of glaucous, green leaves can persist for twenty or more years before a long, stout, flowering stalk is formed. After fruiting the entire plant dies.
