Agave attenuata, , agaves and more agaves

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 no 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 most Agave species' leave;, they are a bright glaucous gray to light yellowish-green and stingless.
 
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:A. attenuata subsp. attenuata: Native to Central and Southwest Mexico and naturalized in Madeira and Libya.A. attenuata subsp. dentata (J.Verschaff.) B.Ullrich: Native to Northwest and Southwest Mexico.[8]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.
