Aloe arborescens (Torch Aloe) A large densely growing succulent shrub to 9 feet tall by an equal spread with branching stems holding many 18 inch wide rosettes of narrow recurved soft-toothed margined leaves that are dull green, yellow-green to sometimes blue-green depending on the location and amount of sunlight received. Coral-red flowers hang tightly on the unbranched inflorescences that rise 2 feet above the foliage in late fall and early winter. Plant in full sun (coast) to light shade. This drought tolerant plant does great in coastal California without any supplementary irrigation and is cold hardy to about 22 degrees F. It has long been in cultivation in California with it being listed as common in Pearl Chase's 1930 book An annotated List of Cultivated Plants Cultivated in Santa Barbara: Cacti and other Succulents. We have been growing this Santa Barbara signature plant since 1982. We also grow the yellow forms Aloe arborescens 'Lutea' and Aloe 'Yellow Torch' and the Aloe arborescens hybrid with Aloe ferox that is called Aloe x salm-dyckiana. This species has an extensive natural distribution in southern Africa, from Mozambique, Zimbabwe and Malawi south through eastern South Africa, and then westward in a strip along the coast nearly to Cape Town. Much of its natural range receives summer or year-round rainfall but in our mediterranean climate this species has adapted well and thrives with our winter rainfall with very little to no summer irrigation. The specific epithet means "becoming a tree" for this plant's large stature, though a bit misleading as this plant is more of a large shrub. While we tend to call this plant 'torch aloe' for its stout vivid red flowers, a common name used in South Africa is Krantz Aloe, named for the Afrikaner word 'krantz' meaning a "rocky ridge" or "cliff" in reference to one preferred habitat, though this plant actually comes from varied habitats from down at sea level up to high in the mountains.  The information on this page is based on our research that has been conducted on this plant in our nursery library, from online sources, and from observations made of the crops growing in the nursery, plants in the nursery's garden and those in other gardens where we have observed it. We also have incorporated comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing Aloe arborescens.
