Agave victoriae reginae is highly variable in form, but in general, the rosettes are small and compact, growing to 0.5m, composed of short, rigid, thick leaves that are green with a pattern of distinctive white markings.
The markings are generally along leaf keels or margins, giving a sort of polyhedral appearance. Marginal teeth are usually lacking, while the terminus of the leaf may include 1 to 3 spines, each 1.5–3 cm in length. Cream coloured flowers are borne in erect racemes up to 4m in length.
