Aloe Polyphylla
Aloe Polyphylla Spiral patterns are found in the body plans of animals including molluscs such as the nautilus, and in the phyllotaxis of many plants, both of leaves spiralling around stems, and in the multiple spirals found in flowerheads such as the sunflower and fruit structures like the pineapple. 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. Aloe polyphylla is commonly known as the spiral aloe in English, kroonaalwyn in Afrikaans, or lekhala kharatsa in Sesotho. The species epithet polyphylla means "many-leaved" in Greek. Taxonomically, it forms part of the Rhodacanthae series of very closely related Aloe species, together with Aloe glauca, Aloe lineata and Aloe pratensis. 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 off-shoots, 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.
