Aloe polyphylla (spiral aloe, kroonaalwyn, lekhala kharetsa) is a species in the genus Aloe that is endemic to the Kingdom of Lesotho in the Drakensberg mountains. It is well known for its strikingly symmetrical, five-pointed spiral growth habit.
Name and taxonomy
Aloe polyphylla is a stemless aloe and grows its leaves in a very distinctive spiral shape. The plants do not seem to sucker or produce offshoots, but from the germination of their seeds they can form small, dense clumps. The fat, wide, serrated, gray-green leaves have sharp, dark leaf-tips.
This aloe flowers at the beginning of summer, producing red-to-pink flowers at the head of robust, branched inflorescences.
The spiral aloe grows in high, mountainous, grassy slopes. Here it clings to rocky crevices and well-drained scree slopes. The climate is cool in the summer and in the winter the aloes are often covered in deep snow. The region also has a very high rainfall and this moisture is augmented by the clouds which engulf the Lesotho mountain peaks.
The species is highly sought after as an ornamental but is difficult to cultivate and usually soon dies if removed from its natural habitat. In South Africa, buying or collecting the plant is a criminal offense.
