Aloe polyphylla: Do not sit here!

Marketed widely in Australia, the spiral aloe or Lesotho’s Aloe polyphylla does very well there. The grey bloom on the smooth outer leaf surfaces makes way for dark green colouring in parts, the margins toothed and yellowish.

Many leaves in picture have no marginal teeth near the leaf tips. The tip itself is spiny, sometimes turned black on older leaves. The leaf keels are strongly off-centre, similar to those in some Gasteria species.
