Spiral Aloes like to be ignored, they grow in decomposed Sandstone. Water once every two weeks and never fertilize because if they grow too fast they won't spiral. One must remember they live in Lesotho which is a mountain kingdom. They don't like hot weather, in fact love being covered in snow during the winter as excessive exposure to wind will dry them out. they are used to -10 to -20 C overnight which usually warms to 10 to15 C during the day, summer temps go to 15 to 22 C so it's a very cool climate.
I have many growing in my garden, rain doesn't bother them unless they are young. To grow the seeds keep them wet at all times do not let them dry out, 10-18 days and you will have success. Keep the soil wet for young ones until they are able to transplant into a larger container.

I have been told by those who propagate this plant from seed at U.C.Berkeley that the key to growing it is to always grow it on a slope or if in a pot,tilt the pot so water never sits in the rosette. Water sitting in the rosette is the greatest cause of rot in these plants. Soil should also drain very well-as standard for all C&S.

Though beautiful, I agree with palmbob about this plant- its a bit of a diva, being super-thirsty and fussy about light levels.
Here in coastal Otago, New Zealand, Zone 9, I underpotted it and stuck it in the bright sunlight, where it shriveled up and sulked, until I caught on to its requirements and gave it some dappled shade. Much happier during our soggy winters than our dry-ish summers, its now fattening up and starting to look more like it should.
Usually I dont persist with fussy customers, but its so potentially beautiful that its worth the effort. We have some huge, impressive specimens down here, up to a metre across- just remember the water and shelter.

This is one of the most ornamental aloes, but in my climate in southern California, it is one of the hardest to keep alive. It hates the heat and will usually perish if not kept moist and cool in summers (need a cool place indoors maybe?). Have lost several despite all efforts. I know some grow this along the coast down here well, but seems much happier in northern California. Don't let the USDA date fool you into thinking this aloe grows like any other.

Update... I have finally had success with this species in southern California, as have others, even without taking it in in hot summers... I have mine in an elevated location off the ground in a pot (less hot there) and in mostly filtered shade. It still brown-tips in the summers, but does pretty well... very slow compared to how it grows in more coastal climates, though. Gotten one through 3 summers and looking really none the worse for wear! Not sure if I will ever get it to flower, though.

Positive Happenstance On Mar 19, 2005, Happenstance from Northern California, CA wrote:

Spiral Aloe is a stemless plant with leaves that spiral.. A 2 year old plant will have 35-45 leaves. Mature plant will have 5 rows of leaves twisting either left or right. This is a hardy Aloe which at about 5 years of age will have approximately 150 leaves.

Needs perfect drainage and and lots of bright light. Full sun to light shade. 9b-11 This is a tough Aloe from high elevations of 7000 - 8000' that can withstand colder temps than most Aloes. Protect from frost and overly wet conditions. A. polyphylla is the only alpine member of the Genus.
