Synonyms:
Description: Conophytum blandum is a small but robust caespitose (groundcover) plant, stemless or with short stems with time.
Bodies (paired leaves): Up to 4 centimetres tall and 2 centimetres thick. The leaves have a low degree of basal fusion, the free leaf-tips (lobes) are about 10 mm long and triangular in shape, keeled and apiculated. The margins are green to red or deep purple in colour. The epidermis is whitish-green to glaucous to deep blue green or brownish pink in colour. The epidermis could be spotted or completely smooth.
Flowers: Large, white to light violet, changing to rose.
Blooming season: The flowers are autumnal (rarely in summer) and diurnal.
Remarks: C. blandum is related to Conophytum herreanthus. There is a similitude in leaves shape rather than in flowers appearance. The leaves of C. blandum are indeed smaller than those of Conophytum herreanthus.

These plants grow on winter rain and head for summer dormancy. They require little water; otherwise its epidermis breaks (resulting in unsightly scars). Water minimally in summer, (only when the plant starts shrivelling), but it will generally grow even in summer if given water. Water regularly in winter after the previous year's leaves have dried up. Requires good drainage. Keep cool and shaded in summer, it needs full sun or light shade. Hardy to -2°C. Ensure a very good ventilation. Avoid to repot frequently. This plant may stay in the same pot for many years.
Propagation: It can be reproduced both by cuttings and seeds. Take the cutting from a grown-up mother plant. Each cutting must contain one or more heads along with a fraction of root.
