Agave americana in bloom in Portugal. The flower stalk may reach up to 8 m (26 ft) in height

Agave americana, common names centuryplant,[4] maguey, or American aloe,[5] is a species of flowering plant in the family Agavaceae, originally native to Mexico, and the United States in Arizona and Texas. Today it cultivated worldwide as an ornamental plant. It has become naturalized in many regions including the West Indies, parts of South America, the southern Mediterranean Basin, parts of Africa, India, China, Thailand, New Zealand, Australia. [6]

Despite the common name "American aloe", it is not closely related to plants in the genus Aloe.

Description

Although it is called the century plant, it typically lives only 10 to 30 years. It has a spread of about 6–10 ft (1.8–3.0 m) with gray-green leaves of 3–5 ft (0.9–1.5 m) long, each with a prickly margin and a heavy spike at the tip that can pierce to the bone. Near the end of its life, the plant sends up a tall, branched stalk, laden with yellow blossoms, that may reach a total height of up to 25–30 ft (8–9 m) tall.

Its common name derives from its semelparous nature of flowering only once at the end of its long life. The plant dies after flowering, but produces suckers or adventitious shoots from the base, which continue its growth.[7]

Taxonomy and naming

Agave americana was one of the many species described by Carl Linnaeus in the 1753 edition of Species Plantarum, with the binomial name that is still used today.[1]

Cultivation

Agave americana is cultivated as an ornamental plant for the large dramatic form of mature plants - for modernist, drought tolerant, and desert style cactus gardens - among many planted settings.[8] The plants can be evocative of 18th-19th-century Spanish colonial and Mexican provincial eras in the Southwestern United States, California, and xeric Mexico.

Subspecies and Cultivars

Two subspecies and two varieties of Agave americana are recognized by the World Checklist of Selected Plant Families:[9]

  • Agave americana subsp. americana
  • Agave americana subsp. protamericana Gentry
  • Agave americana var. expansa (Jacobi) Gentry
  • Agave americana var. oaxacensis Gentry

Cultivars include:[10][11]

  • 'Marginata' agm[12] with yellow stripes along the margins of each leaf
  • 'Mediopicta' agm[13] with a broad cream central stripe
  • 'Mediopicta Alba' agm[14] with a central white band
  • 'Mediopicta Aurea' with a central yellow band
  • 'Striata' with multiple yellow to white stripes along the leaves
  • 'Variegata' agm[15] with white edges on the leaves.

(those marked agm, as well as the parent species,[16] have gained the Royal Horticultural Society's Award of Garden Merit).

Uses

Tools used to obtain agave's ixtle fibers, at the Museo de Arte Popular, Mexico City D.F.

Culinary

If the flower stem is cut without flowering, a sweet liquid called aguamiel ("honey water") gathers in the heart of the plant. This may be fermented to produce the drink called pulque. The leaves also yield fibers, known as pita, which are suitable for making rope, matting, coarse cloth and are used for embroidery of leather in a technique known as piteado. Both pulque and maguey fiber were important to the economy of pre-Columbian Mexico.

In the tequila-producing regions of Mexico, agaves are called mezcales. The high-alcohol product of agave distillation is called mezcal; Agave americana is one of several agaves used for distillation. A mezcal called tequila, is produced from Agave tequilana, commonly called "blue agave". There are many different types of mezcal some of which may be flavored with the very pungent mezcal worm.[17] Mezcal and tequila, although also produced from agave plants, are different from pulque in their technique for extracting the sugars from the heart of the plant, and in that they are distilled spirits. In mezcal and tequila production, the sugars are extracted from the piñas (or hearts) by heating them in ovens, rather than by collecting aguamiel from the plant's cut stalk. Thus if one were to distill pulque, it would not be a form of mezcal, but rather a different drink.

Agave nectar, also called agave syrup, is marketed as a natural form of sugar with a low glycemic index that is due to its high fructose content.[18]

Heraldry

The plant figures in the coat of arms of Don Diego de Mendoza, a Native American governor of the village of Ajacuba, Hidalgo state.[19]
