Lapeirousia fabricii plants flower close to the ground, at best reaching 25 cm in height.

The tepal margins are wavy, in some parts crisped in open flowers. The smaller, lower tepals have somewhat heart-shaped dark red markings and are slightly paler cream than the unmarked upper three. The long corolla tubes are darker on the outside than on the spreading, cream lobe insides and lined, particularly in their central parts.

The branched style is visible over the flower centre, the blackish anthers immediately below them. 

Buds and several blue-green floral bracts promise more flowering later. Some short, broad-tipped leaves are visible below the open flower in the foreground (Manning, 2007; Manning and Goldblatt, 1997).
