Century plant, Parry’s agave, mescal agave
Varieties of Parry’s agave are native to Arizona and Mexico, between 4000-9000' (1.2-2.7 km) in elevation. Few sources acknowledge this variety, but I couldn’t resolve the uncertainty.
Identification: Rosettes reach 24" (60 cm) tall and 3' (91 cm) around, and resemble giant artichokes. Leaves are 10-16" (25-40 cm) long and 3-5" (7.6-12 cm) wide, wide and flat or somewhat oval in shape, tapering to a sharp dark tan, brown, or black tip. They are smooth and rigid, about ½-¾" (1.3-1.9 cm) thick, edged with teeth, light grayish- or bluish-green. The flower stalk is 11-20' (3.4-6.1 m) high, branched at the top into 18-30 branches, each with bright lemon yellow flowers. Flowering occurs between June and August.
Edibility: Indigenous peoples including the Apaches prepared this agave in many different ways as a food source.
