The bracts, which are reduced leaf or leaflike structures at the base of a flower, are egg-shaped and gradually narrowing to a long point, thin, dry and brown in colour.

Aloe dominella flowers in June to October. The flowering usually occur after fires followed by the rain. Aloe dominella is associated to Aloe chortolirioides var. woolliana in terms of growth conventions, such as the growth of stems in constricted groups and size of leaves’ rosettes, however, A. dominella is distinguished from A. chortolirioides var. woolliana by its flower size and colour. A. chortolirioides var. woolliana produces pinkish-reddish flowers about 40 mm long, while Aloe dominella produces yellow flowers of about 18 mm long.
