Agave polianthiflora is a member of the group Parviflorae. It grows in Mexico in limited areas near the Sonora - Chihuahua border and one of the smallest species of the genus. The rainfall in the region is enormous and is 1,000 mm per year. Typical are the variably arranged, weißfaserigen leaf margins. Unique is the long -tubed, red-colored bloom. It is hard to distinguish from the Parviflorae members Agave parviflora and subspecies flexiflora, but which have the smallest, yellow-colored flowers of the species of the genus.
