''Agave attenuata'' is a species of agave sometimes known as the "lion's tail," "swan's neck," or "foxtail" for its development of a curved stem, unusual among agaves. Native to the plateau of the State of Jalisco in central Mexico, as one of the unarmed agaves, it is popular as an ornamental plant in gardens in many other places. It is reportedly naturalized in Madeira and Libya.〔http://www.cactus-art.biz/schede/AGAVE/Agave_attenuata/Agave_attenuata/Agave_attenuata.htm〕 The stems typically range from 50 to 150 cm (20–60 in) in length, and eventually old leaves fall off, leaving them 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 no teeth, nor terminal spines, although the leaves taper to points that fray with age. The inflorescence is a dense raceme 2.5 to 3 meters (8 to 10 ft) high, with greenish-yellow flowers.〔Howard Scott Gentry, ''Agaves of Continental North America'' (University of Arizona Press, 1982) pp. 66-71〕 Specimens were sent to Kew by the explorer Galeotti in 1834, from an unspecified location in central Mexico. More recent study has reported it from Jalisco east to Mexico, in small colonies at elevations of , but there have been few sightings, suggesting this agave is rare in the wild.〔 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.〔(Agave attenuata ), The Lovely Plants〕 Image:Agave attenuata Pot 2250px.jpg|Plant in a pot Image:Agaveattenuata1web.jpg|A specimen leaning as the stem grows Image:Agave_attenuata_flowering.jpg|Flowering Image:Agave_attenuata_flower_stem.jpg|Flower stem closeup Image:Agave_attenuata_flowers.jpg|Flower closeup Image:Agave attenuata Closeup 3264px.jpg|Closeup ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Agave attenuata」の詳細全文を読む スポンサード リンク
