Description

Aloe plicatilis can grow to a height of 3–5 m (9.8–16.4 ft) tall. The trunk has corky, fire-resistant bark and the branches are forked ("dichotomous"), with masses of succulent, oblong, tongue-shaped leaves arranged in 2 opposite rows like a fan - hence its common name "Fan Aloe" (Likewise its scientific name plicatilis also means "fan-like" or "pleated") . To the imaginative, the leaf-heads look a bit like a mass of grey hands, raised in the air.

The leaves are grey-green in colour and about 300 mm long and 40 mm wide, and have tiny teeth along the margins that are noticeable only on close inspection.

Aloe plicatilis is one of only four species of aloe in the world which display this unusual fan-like arrangement of its leaves. Two of these species occur only in Madagascar

The plant grows slowly, and is an attractive and interesting accent plant for sunny planting exposures.

Propagation
Fan Aloes are best propagated from cuttings (truncheons). These should be stems or branches, cut cleanly from the parent plant. After allowing the cutting to dry out (not in direct sunlight) for a week or two, plant it in well-drained soil in a reasonably sunny position - out of reach of competition from faster growing plants. It prefers soil of a medium or slightly acidic pH.
