Aloe spinosissima
Spider Aloe
The Aloe spinosissima, commonly known as the Spider Aloe, is a suckering shrubby aloe of garden origin, forming dense low clumps of slender stems each topped with a rosette of narrow, recurved, spine-edged grey-green leaves. Slim orange-red flower racemes are carried through the cool season.
It fills ground faster than most aloes at its size and holds a spiky, textural mass that works well on banks and in wide beds. It is used in median and roundabout planting, on slopes and in gravel gardens.
