Aloe arborescens, Krantz Aloe)
Family: Asphodelaceae
Hardiness: to 22 degrees F.

Perennial succulent native to South Africa.  Growing up to 8 feet tall, the plant flowers coral-red in the fall and/or winter.  Plants produce one or more upright stalks with the showy rosettes perched on top, leaves rimmed by large, soft and harmless spines, filled with gel, also laden with the yellow anthroquinone known as "aloin."   Like Aloe Vera, Aloe arborescens is a preferred species for production of aloe gel, which contains alantoin and speeds healing of open sores, cuts and scratches quite noticeably.  Great for treating sunburn.  Aloe arborescens is listed in "Aloes of South Africa" as one of the four main species used medicinally. The leaves of the plant, containing both the anthraquinone-laden underskin and the gel, are used in making anticancer medicines for treating advanced stages of cancer--after metastasis.  This activity is attributed to 3 different mechanisms:  antiproliferative, immunostimulatory and antioxidant. Here is a link to more information about the active constituents in Aloe arborescens and its use in treating cancer  http://www.aloearborescens.org/SciResearch4.pdf

Aloe arborescens is an excellent choice for potted culture anywhere, or outdoors culture in maritime California, desert areas and the South.  When left in potted culture, keep indoors in a bright window, in the shady greenhouse or on the porch in the summer, then bring in for the winter.  Drought tolerant, but also, among the Aloes we've grown, more tolerant of cold and "wet feet" than most.  "Krantz" is the Afrikaner word meaning "cliff" or "rocky ledge," referring to the natural habitat. Plant prefers dry to mesic soil and full sun to part shade.  Sow seed in regular greenhouse conditions.  Probably ok to start them on a windowsill, although high temperatures and humidity do encourage germination.  Planted in the right conditions, these seeds give high germ rates. Use a pot or a deep flat filled with Cactus mix.  Sprinkle seed on surface and cover with 1/8 inch of sharp, coarse sand or grit.  Lacking sand or grit, you can cover with cactus mix, or very small pea gravel.  Tamp well and water once or maybe twice daily, keeping warm and somewhat shaded.  A shaded bench in the greenhouse is ideal--we're looking for filtered light here, not heavy shade.  Germination occurs in 1 to 3 weeks, the little succulent leaves pushing up through the grit.  Seedlings of Aloe arborescens make a very long first leaf--about 1.25 inches, before pushing out the second leaf, which appears stubby at first, and then elongates.  Keep seedlings warm, somewhat shaded and water a bit more sparingly (once every three days), allowing the surface to dry out between waterings.  Grow seedlings closely together for 3 months to a year, then individuate to pots.  To plant (any) Aloe, first cover the hole in the bottom of the pot with a pot shard, put a layer of sand in the bottom of the pot (2 inches or so deep), then a 2 inch or so layer of compost or any kind of humusy potting soil will do, then finish off with more sand on top of the compost.  Plant the roots of the aloe seedling down through these layers, and leave the succulent barely nestled down into the top layer of sand, tamping all around to hold the seedling firmly upright.  Do not water after transplanting--leave the plants for a week or 2 without watering at all.  The seedlings will send down roots at this time, roots that would be discouraged by the presence of too much moisture.  Once the plants have rooted in, water once a week or so during the summer, but then more or less discontinue watering during the winter.  Aloes do best in a shaded greenhouse or indoors on the windowsill with a northerly or easterly exposure.  Aloes live on and on.

Aloe arborescens is worthy of our attention. Originally from South Africa, this beautiful tree Aloe thrives in dry and frost free zones worldwide, and has long been employed by horticulturalists. A stunning plant for the garden margin, it can be used as a hedge, growing to 9 feet tall and creating highly colored flowering racemes in season. As a potted plant, it does well indoors in a sunny window, or in the greenhouse. I've found this species to be more resilient than Aloe vera--more frost hardy, more resistant to overly wet conditions, and able to withstand more direct sunlight. The gel from A. arborescens is interchangeable with that of A. vera in treating abrasions and burns, demonstrating an antibacterial, soothing and pain relieving effect. It speeds healing and reduces inflammation and infection. A. arborescens is potent--leaf extracts and raw leaves have been used by those suffering from cancer. There is an immune enhancing effect. The plant is loaded with bioactive polysaccharides. Containing high concentrations of aloe resin and barbaloin, Aloe arborescens acts as an antiproliferant to aberrant cells, also containing anthraquinones that help move dead cells and toxic debris out of the body. Like many plants, there is a combination of molecules involved that synergise to create the healing effect. Its just that Aloe arborescens is a little better at this than most
