Agave attenuata is a species of flowering plant in the family Asparagaceae, commonly known as the foxtail or lion's tail. The name swan's neck agave refers to its development of a curved inflorescence, unusual among agaves. [3] Native to the plateaux of central west Mexico, as one of the unarmed agaves, it is popular as an ornamental plant in gardens in many other places with subtropical and warm climates. [4]

Description

Agave attenuata Pot 2250px.jpg

Although the plant can appear acaulescent, stems often reach 50 to 150 cm (20–60 in) in length, and old leaves fall off, leaving the stems visible. The leaves are ovate-acuminate, 50–70 cm (20–28 in) long and 12–16 cm (5–6 in) wide, pale in color, ranging from a light gray to a light yellowish green. There are neither teeth, nor terminal spines, although the leaves taper to soft points that fray with age. The numerous, broad, succulent, tapering leaves are slightly less rigid than the leaves of most Agave species; they are a bright glaucous gray to light yellowish-green and stingless. [5]

The inflorescence is a dense raceme 2.5 to 3 meters (8 to 10 ft) high (usually curved), with greenish-yellow flowers, growing after many years. [6] As with other Agave species, the plant dies following seed development, but numerous suckers consequently sprout, both from the base of the plant and from the flower raceme.

It has two subspecies:

Etymology

The Latin specific epithet attenuata means "with a narrow point". [9]

Range

Specimens were sent to Kew Gardens by the explorer Galeotti in 1834, from an unspecified location in central Mexico. A more recent study has reported it from Jalisco, east to Mexico State, in small colonies at elevations of 1,900 to 2,500 meters (6,200 to 8,200 ft), but there have been few sightings, suggesting this agave is rare in the wild. [6] IUCN reports the species from the states of Colima, Durango, Guerrero, Jalisco, Michoacán, Nayarit and Mexico State, at altitudes between 400 and 2,500 meters (1,300 and 8,200 ft) on volcanic rock cliffs within pine forests and transitional zones of tropical dry and temperate forests types in mountains. [1] It is reportedly naturalized in Libya [10] [11] and Madeira [11] and is widely spread through the Mediterranean and the rest of Macaronesia.

In cultivation, Agave attenuata is said to prefer relatively moist loamy soil, although it can cope with poor soil and dry conditions. It should be protected from direct sunlight in summer and from long periods of frost. [12] It is hardy down to USDA Zone 9b. [13] [14]

<i>Agave shawii</i> Species of succulent plant from North America

Agave shawii is a species of monocarpic succulent plant in the genus Agave, commonly known as Shaw's agave. It is a rosette-forming plant characterized by glossy, green leaves with toothed margins. After several years of slow growth, the plant puts all of its resources to produce a towering stalk of flowers, and then dies. The death of the flowering rosette is compensated by the growth of numerous clonal pups. This species is segregated into two subspecies, one native to the coast of southwestern California and northwestern Baja California, known commonly as the coast agave, and another native to the Baja California desert, known as the Goldman agave.

<i>Agave</i> Genus of flowering plants closely related to yucca

Agave is a genus of monocots native to the hot and arid regions of the Americas and the Caribbean, although some Agave species are also native to tropical areas of North America, such as Mexico.

Agave now includes species formerly placed in a number of other genera, such as Manfreda, ×Mangave, Polianthes and Prochnyanthes.

<i>Agave atrovirens</i> Species of flowering plant

Agave atrovirens, called maguey verde grande is a type of century plant native to Oaxaca, Puebla and Veracruz states in Mexico. It is the largest of all the Agaves, occasionally reaching a weight of two long tons. Each succulent leaf can be up to 14 feet 9 inches in length and weigh one hundred pounds (45 kg) apiece. In the variety A. a. cochlearis these leaves can also be up to 16 inches (41 cm) wide. As in other Agaves the leaves form a rosette, from the center of which, after many years, a panicle of flowers emerges on a long scape or peduncle which at first looks like a vast stalk of asparagus, but later grows to more than forty feet in height, develops side branches near the top and numerous flowers which open red and gradually turn yellow. Agave salmiana, the species with the tallest inflorescences, is frequently lumped with A. atrovirens as the varieties A. a. salmiana or A. a. sigmatophylla. If this is valid, then A. atrovirens also has the tallest inflorescences of any Agave, and of any known plant. Each rosette flowers and fruits once, then dies. According to Fayaz this is one of the species which makes offsets or "pups". A. atrovirens is one of the pulque agaves used in the production of mezcal.

<i>Dudleya hendrixii</i> Species of succulent
