Aloe polyphyllaSpiral aloe. From the high Maluti Mountains of Lesotho where it sometimes sees snow. Harvesting for specimen plants have devastated wild populations. The fact that the plant does not sucker but depends on seeds for propagation contributes to its rarity in the wild. Photographed at University of California Botanical Garden, Berkeley, CA.
