This is a great South African species for cultivation in California. It was initially lumped in with Aloe striata (which, interestingly, has NO striations) but is now considered a separate species (and I think rightly so). It is a relatively large, stemless species with very soft, flexible leaves and NO marginal teeth (few aloes have this feature) and very ornamental striations (parallel lines) the length of each leaf. It also differs from Aloe striata in its flowering time, which is usually in the summer, though some flower as early as spring and as late as late summer/early fall. Inflorescences consist of highbranched, open racemes of deep pink flowers. These flowers and flowering times differ from Aloe striata which flowers in late winter only, and has orange flowers on much less complex inflorescences.

This is a bit of a mildly fastidious species, prone to rot and easily traumatized due to its soft flesh. Does OK in full sun but appreciates some shade in extremely hot climates. Compared to Aloe striata it is a relatively slow grower. But once mature it is a beautiful specimen and often attracts comments due to its striking foliage. Pretty good cold hardiness down near 20F

It's done extremely well in a very sunny, very moist spot here in Tucson. It's outgrown the space even more now in the 6 months since this photo was taken. It always looks dirty due to the white coating getting rubbed off and pools of dusty rainwater forming in the leaves. Quail nest underneath it every spring. I have another in a much drier spot - will get a photo.

My other plant, in some shade and a bit dryer. It seems that it would still appreciate some more shade, since it curls up on itself a bit. The acacia above it is growing as fast as it can!

I did not realize at the time that they were so rare. Had I known I would have begged the lady to sell me one. It was a nursery in Gran Can, but most of the plants on sale were cactus and much smaller. The Canary Islands are interesting to visit both for their native plants, and regular succulents. Jkw

Still flowering after transplanting to the new house, though the plant itself looks pretty beat up.

As is typical - mid-summer flowering means the temperature is too high for the flowers to mature and open properly.
