Aloe arborescens 'Spineless' (Toothless Torch Aloe) A large densely growing succulent shrub to at least 5 feet tall (the species can get 8 to 9') by an equal spread with branching stems holding many 18 inch wide rosettes of narrow recurved nearly toothless leaves that are dull yellow-green and blushing a orange pink when drought stressed. Coral-red flowers hang tightly on the erect few branched inflorescences that rise 2 feet above the foliage in late fall and early winter. Plant in full sun (coast) to light shade. Like the species, which differs mostly in having toothy leaf margins, this drought tolerant plant does great in coastal California without any supplementary irrigation and is cold hardy to about 22 degrees F. For more information see our listing for the species, Aloe arborescens. This plant should really be called "Toothless" as the projections along the leaf margins of an aloe are typically called teeth and the term spine usually reserved for those projections that arise elsewhere on the leaf, but "Spineless" is the name first used for this cultivar, though we have not been able to determine its actual origin. We first saw this intriguing plant pictured in Jeff Moore's fantastic book Under The Spell of Succulents published in 2014 and knew right away that we must grow it. We already grew the species Aloe arborescens, two yellow forms, Aloe arborescens 'Lutea' and Aloe 'Yellow Torch', as well as the Aloe arborescens hybrid with Aloe ferox that is called Aloe x salm-dyckiana (AKA Aloe princeps) so knew this species grows very well in California gardens. Luckily we were able to obtain 'Spineless' in 2015 from the Institute of Aloe Studies (ISA) as ISA 15-003c.

We also note those observations we have made of this plant as it grows in the nursery's garden and in other gardens, as well how crops have performed in our nursery field. We will incorporate comments we receive from others, and welcome to hear from anyone who may have additional information, particularly if they share any cultural information that would aid others in growing it.
