Gardeners' Notes:

Probably thrives better in the winter rainfall areas of California, but seems to have no real trouble with our bimodal rain in the Arizona desert. Tolerates heat, frost, some morning sun and flowers reliably every year. Nice plant.

Nice aloe it can grow up very much, it flower in winter and can withstand pretty hard freeze if kept dry

Seems to flower most of the year. However main flowering time is mid winter. Flowers are single racemes topped with reddish to orange flower. Usually the top of the flower remains a ball until near the end of flowering. Lowest parts droop, then fall off and upper flower parts, that were upright, then start to droop- this continues until ball opens up at top and then flower is done. Flowering part of raceme only 6" long.

Very variable species with some forming small colonies of plants 8" or so in diameter, while others are solitary, eventually stem-forming, toothy plants of pale blue to deep blue-green and diameters up to 16". Flowers of the larger forms usually orange and tall (3') while colony forming plants have inflorescences usually under 10"
