The stems are covered in closely spaced spirally arranged leaves with a tight rosette at the tip.

In bright sunlight leaves may become reddish-brown.
There are teeth around the whole leaf edge and 2 smaller ones on the pointed tip.

Flowers are on a short pedicel with a small bracteole at the base.
The tubular flowers only have a very slight constriction above the ovary.
There are 6 tepals with the 3 in the outer whorl being fused for around three-quarters of their length.
All the tepal lobes curve back.
Species flowers are described as red to red-orange with yellow and green tips.

(Aloe zanzibarica is sometimes seen as a synonym of A. juvenna but according to Kew and the IPNI it is a synonym of A. squarrosa.
The two plants are often confused but A. squarrosa only has a terminal rosette with leaves below dying off leaving a bare stem.
The more widely spaced green and white spotted A. squarrosa leaves are larger, longer and curved.
