Spiral aloe
AdvancedAloe polyphylla
A stemless aloe whose broad grey-green leaves form five ranks in a striking clockwise or anticlockwise spiral. Found only in the high mountains of Lesotho and listed in CITES Appendix I.
About
Aloe polyphylla is endemic to the Maluti (Drakensberg) mountains of Lesotho, where it grows at 2,000–2,500 m in basalt crevices and on well-drained scree of steep slopes. Winters can bring snow, and summers are cool, with ample rain and mist. Its hallmark is the leaf arrangement: five ranks of 15–30 leaves spiral neatly clockwise or anticlockwise, about 150 leaves per plant, hence the name 'many-leaved'. The broad grey-green leaves end in sharp, dark purplish-brown tips and have irregular marginal teeth. Dull-red to salmon-pink, occasionally yellow flowers are borne in compact heads on branched inflorescences in spring and early summer. It rarely offsets, so wild populations regenerate only from seed. Collecting has reduced wild numbers, and in South Africa it is illegal to remove plants from habitat or buy them from roadside sellers. Plants taken from the wild seldom survive more than a few years, and it is considered difficult in cultivation; a US grower notes it is thirstier than most aloes and does best in cool climates. Plants sold in Japan are seed-raised or tissue-cultured, mainly through specialist nurseries, and because it is a CITES Appendix I species a registration certificate is required for any sale in Japan.

Size of the Spiral aloe
The Spiral aloe grows to About 30 cm tall, 30–60 cm across.
Basic Info
Origin
Lesotho (Maluti Mountains, 2,000–2,500 m)
Lifespan
Perennial; rarely offsets and usually stays solitary
Size
About 30 cm tall, 30–60 cm across
Temperature
5〜35℃
Humidity
30〜50%
Watering & Fertilizer
Feed sparingly in the growing season
Growing Tips
Light & Placement
Bright sun to light shade. It comes from cool high mountains, so in hot weather keep it airy and cool and soften strong sun.
Watering
Considered thirstier than most aloes. In the growing season water thoroughly when the mix dries, provided it drains freely.
Temperature & Overwintering
Cold-hardy; a US grower rates it to around -12°C. Hot, humid summers are the main challenge, when heat and stagnant air damage it.
Soil & Repotting
It grows in rock crevices and scree, so use a very coarse, gritty, well-aerated mix.
Propagation
It rarely offsets, so propagation is from seed; plants in trade are seed-raised or tissue-cultured.
Pests & Cautions
As a CITES Appendix I and Japanese Internationally Endangered Species, transfers require a registration certificate, including for plants propagated in Japan; always check that one comes with the plant.

Taxonomy & Authority
Regulations & Conservation Status
Listed in CITES Appendix I; commercial international trade is essentially prohibited. In Japan it is designated an Internationally Endangered Species under the Act on Conservation of Endangered Species of Wild Fauna and Flora, so any transfer (sale or gift) or display/advertising for sale requires a registration certificate for each plant, including plants propagated in Japan. Unregistered plants cannot be sold.
