Agava is a genus of Asparagaceae in about 200 species of arid and semi-arid regions of the United States, especially in Mexico and the Caribbean. There are several economically important species in the genus, especially the blue weeds used for tequila which are needed to make muscular fluids. Agava is a homogeneous species in the warm and dry regions of the United States, although some agave species are endemic to the tropical regions of South America. The Aztecs valued Agora as a gift to the gods and used the liquid from its origin to taste food and drink. Weed plants are the genus that can be considered as perennial, as they require a few to several years to mature and flower. However, most agave species are more accurately described as exclusive rosettes or multanuals, since each distinct rosette flower dies only once and then a small number of agave species are polycarpous.
The shallows are characterized by roses of curved or leathery leaves, ranging in size from a few centimeters to 2.5 meters (8 feet), depending on the species. Most bears have spines along the edges and leaves, for which they occasionally get confused with the cacti. When the flower stalk dies, the parent tree dies, but usually not before the new “slipping” is spread at its root. Many species can reproduce botanically and are able to produce clonal rosettes at the base of the root stem or through nearby groundwater rhizomes; Some species produce bulbs (bulb-like structures that can form new plants) on the flower. The plants are usually exclusive in that each rose dies after flowering and fruit and most do not live more than 30 years. Agaba crescent with pink-yellow flowers; It descends to a higher elevation in the Arizona Fairland in south-central Arizona. It is the most densely concentrated area north and east of both Phoenix and Tucson, northeast of the Sonoran Desert. As an adaptation to their dry habitat, the agaves use a salicylate pathway called crassulacean acid metabolism (CAM), in which carbon dioxide is fixed overnight to limit the amount of water lost from the leaf stomata.
Closely related genera are plants from Yucca, Hesperiauca and Hesperello as well as various agave species popular ornamental plants in hot, dry climates, because they require very little supplemental water for survival. Some species of fibers can still be removed by attaching the terminal vertebrae to the leaf, creating a kind of needle and thread. In many species, rose petals are removed to express thicker stems, or “hearts”, which can be roasted and eaten directly or in edible patties on the ground. Most agave species grow very slowly. Some agave species are known as “Century Plants”.
