An extremely decorative species from southwestern Mexico where the gypsum hills of its native range give it its technical name. Smallish to about 30 inches or slightly larger, it has spectacularly wavy or undulating leaf margins that are dentate or bear large but soft teeth.
The coloration is glaucous, bluish-gray and is very attractive. A shy bloomer, it reproduces mainly from offsets. Somewhat slower than many cultivated Agaves, making availability sporadic.
