The inflorescence of Aloe microstigma is an unbranched, narrow, oblong to conical raceme of up to 1 m. Two or three racemes may grow simultaneously on mature plants in good condition. The buds are red or orange, remaining orange or turning yellow upon opening, as in the specimen in picture. The bicolour form is more prevalent.

The bud tips initially show a bluish-grey colour. The bracts at the base of the individual flower pedicels (stalks) are small, not covering the perianths even in bud, although not all the relevant literature agrees with this. The individual flowers or perianths bulge near the centre.

This Aloe species responds well in cultivation, provided that the soil is well-drained and the plant's position is protected from too much cold (Reynolds, 1974).
