Agave parviflora Torr.
Smallflower agave, smallflower century plant
This species is native to a small area of southern Arizona and northern Sonora, Mexico. It is threatened by loss of habitat.
Identification: For agaves, at least, these are just little fellers, 4-6" (10-15 cm) tall and 6-8" (15-20 cm) around. They may be solitary plants or growing in dense tufts that probably originated from a single plant. Leaves are 2-4" (5-10 cm) long and less than ½" (1.3 cm) wide, dark green, with white imprints from the bud. Short, curly white filaments like those in yuccas are present. Yellow flowers appear atop a spike 3-6' (91-182 cm) tall. About two years after flowering, the plant dies, like most other agaves.
