Two cuttings i was given last summer have rooted with pups and in typical easy Aloe fashion. Aloe squarrosa had no problems handling ~32F cold two nights in the eastbay area. Unusual color,a nice contrast to many succulents.

My a. squarrosa is also perfectly happy in full, brutal TX sun. It lives in the pocket of a strawberry pot. During rainy spells I cover plant with a tarp for fear of it rotting. Don't know if necessary, but I take the precaution.

Attractive neat short-stemmed clustering aloe with stiff, markedly recurved pale green to yellow-green spotted leaves (some forms have no spots and are darker green)heavily armed with white marginal teeth. From the islands of Socotra, off Africa. In my zone this is a very slow growing aloe and very little growth is appreciable in 3 years in the garden. So far mine have not produced any offsets. Seems perfectly hardy in full, hot sun however.
