Gardeners' Notes:


On Jul 13, 2011, Fires_in_motion from Vacherie, LA (Zone 9a) wrote:

A delightful aloe with a hurricane-esque overall form, due to the slight curvature of the ends of each leaf, and a beautiful bluish color. Mine doubled its size since buying it in March, but today I had to unfortunately cull it due to aloe mites. It was grown by Altman Plants, which seems to be the main vector for this pest, as they supply much of America's succulents.

I have both the 'spinossisima' green variety and the 'gold tooth' variety, which seems more like arborescens with its longer leaves and looser form.
Both seem very hardy (zone 9 roughly, coastal Otago, New Zealand) and will take a lot of abuse.
Untroubled by hail (many aloes are scarred by this) these varieties are great fillers for a massed display and pup profusely, making them good value, with the bonus of attractive flowers.
Recommended as infill plants in difficult situations, but not really a superstar in itself when compared to more exotic and showy looking species.

Densely clumping, branching multistem cross with a lot of horticultural appeal. Has the basic shape of Aloe arborescens, only a bit more compact, and the wartiness of aloe humilis. Leaves are slight recurved, stiff, pale green and warty, with red flowers in winter. Sometimes sold as Aloe spinossisima, but should be called Aloe X spinosissima
