Additional comments: Queen Victoria agave is a highly desirable, very small desert agave for accentuating small 'desert theme' landscape spaces where visual detail is desired. It is not for large expansive landscape spaces. This agave is definitely on my list of "very cool plants that I gotta have in my yard". The cultivar 'Porcupine' is clonal selection from Shady Oaks Nursery and has very thick compact green leaves with white leaf edges that makes it look like "an artichoke carved out of green stone". The cultivar 'Golden Princess' has smooth dark green leaves edged with a broad yellow margin and patterns of white markings on the leaf tapering to a small terminal spine.

Agave ferdinand-regis is very similar in appearance to Queen Victoria agave and as a result there is much confusion in differentiating between the two species. Agave ferdinand-regis x scabra (shark skin agave) is a compact hybrid without the leaf marginal patterns of striation.
