description
Agave cerulata forms small rosettes that form abundant offshoots. They reach heights of up to 50 cm. The variable, slender, rarely transversely banded, yellow to light green colored, long, pointed, lanceolate leaves are 25 to 50 cm long and 4 to 8 cm wide. The sometimes wavy, leaf edges are toothed flexibly. The needle-like light to dark gray terminal spine is 3 to 6 cm long.
The panicle inflorescence becomes 2 to 3.5 m high. The buds are white and waxy. The light yellow flowers are 45 to 60 mm long and appear on the upper part of the inflorescence on small, irregularly arranged branches. The flower tube is broadly funnel-shaped.
The elongated three-chamber capsule fruits are 30 to 50 mm long and 12 to 13 mm wide. The black, irregularly shaped seeds are up to 5 mm long and 3 mm wide.
