(Baja California - Zone 11b) on Jul 15, 2019 8:02 PM concerning plant:
Solitary or offsetting Arabian highland aloe with decumbent stems to about 14 feet long. Leaves are glaucous and gray-blue, blue-red or purple, with red margins and hooked teeth. Inflorescences are tall and unbranched (or with one branch), with red (occasionally yellow) flowers that have far exserted style and stamens. They appear in fall and winter.
Found growing on rocky slopes and cliffs in southwestern Saudi Arabia and western Yemen at about 6000-11,500 feet, in locations with mist and fog. Rainfall in these areas is 19 inches or more and summers are mild. This is the highest altitude Arabian aloe. It is found associated with A. vacillans and A. castellorum, as well as Aeonium leucoblepharum and Dracaena serrulata. It is similar to A. pseudorubroviolacea but smaller and more prolific, with fewer branches on its inflorescence, flowering in winter and not spring. It is related to 2 other species which have similar flowers, A. porphyrostachys (stemless) and A. schoelleri (yellow to pinkish orange flowers).
