Both the current name and its synonym D. robustum refer to the unusually sturdy appearance of this species compared to other Delospermas.
The plants form erect shrubs up to 30 cm tall, with a basal stem up to 4.5 cm in diameter. They have yellowish brown branches, which are covered in small papillae when young.
The leaves are erect to spreading, more or less round in cross-section, 1.5-2.5 cm long and up to 3 mm thick, bright green and velvety.
In July-August the mainly straw-coloured flowers appear; they are solitary and up to 2.5 cm in diameter, with a few staminodes (yellow with a white base) .
The distribution area is from Kamieskroon to Vredenburg and the plants are found on stony ground.
Pictures were taken earlier this month on the Knersvlakte.
