About plant names...

This hearty aloe grows to 12-18' (3.7-5.5 m) in height. It is a South African native.

Identification: This large aloe has a single stem, and is 6½-13' (2-4 m) tall. Leaves are gray-green to bluish-green, up to 5' (1.5 m) × 10" (25 cm) in size, broader than those of many aloes and tapering to a sharp tip. Maroon-colored teeth with orange tips occur along the leaf margins, and the leaf surfaces have spines. The brilliant flower clusters, varying from yellow to orange or bright red, are its standout feature. A variant, Aloe spectabilis, is no longer considered a distinct species.
