The yellow or lemon-yellow flowers of Aloe kraussii grow in compact, head-like, simple racemes. These heads are broader than long and sometimes appear corymbose. There are from 30 to 40 flowers in an inflorescence. Three or four flower stems may grow in a season from a leaf cluster, becoming up to 40 cm tall.
The perianths or individual flowers taper roundly from the base into the pedicels, their mouths slightly upturned. The buds are erect at the beginning, nod when open. The longest pedicels are on the lowest flowers, about 3,5 cm while the perianths are only about 1,7 cm long. Green veins near the perianth mouth end in a brown spot where the veins converge.
The anthers are exserted about 3 mm, the style to 5 mm. The pale green ovary is 4 mm long, while the later fruit capsule is 27 mm long and six-grooved (Craib, 2005; Pooley, 1998; Reynolds, 1974; iNaturalist).
