About Agave victoriae-reginae

Agave victoriae-reginae · also called Queen Victoria agave, royal agave · houseplant

Queen Victoria agave is a compact, exquisitely geometric agave forming a dense dome of stiff dark-green leaves each penciled with white margins and keel lines. Slow and long-lived, it is a prized specimen plant for sun and sharp drainage. Unlike many agaves it offsets little, relying on its tidy symmetry. Monocarpic, it flowers only after decades.

Preferred mix: Extremely free-draining gritty mineral/cactus mix
