Aloe x spinosissima (Spider Aloe) - This succulent hybrid is one of the more manageably-sized aloes, growing to about 3 ft. tall in flower and spreading into clumps of the same width. Red flowers on an unbranched inflorescence in winter. The name Aloe x spinosissima suggests something ferociously spiny but the teeth that line the leaf margins are not very large or sharp. New rosettes grow from the base of the old ones. Plant in full sun. Hardy to 22-25 F. This is a great midsized landscape aloe but unfortunately seems quite attractive to aloe mite. It is an old hybrid whose origins seem lost in time. It has long been in cultivation in California as evidenced by its listing in the 1930 publication Cacti and other Succulents: An Annotated List of Plants Cultivated in Santa Barbara that was written by Ralph Hoffman, E.O. Orpet, Eric Walther and James West and edited by Pearl Chase. In this book it is listed as a hybrid between the toothy form of Aloe humilis known as var. echinata and A. arborescens var. pachythyrsa, but both varieties have now been synonymized with their associated species. It is sometimes sold as Aloe arborescens 'Dwarf'. The name is the superlative form of 'spinosus', which means spiny so would mean "very spiny" or "superlatively spiny".
The information on this page is based on research conducted about this plant in the San Marcos Growers library, from online sources, and from observations made of the crops growing in our nursery, plants in the nursery's garden and those in other gardens where we may 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 x spinosissima. |
