Water	Sparingly during the cool growing season; keep completely dry through hot summer dormancy
Soil	Fast-draining mineral mix (see Soil and potting mix)
Temperature	Keep above freezing; brief light frost tolerated when bone dry; USDA zones 9b–11

Toxicity	Not known to be toxic to cats and dogs

Cheiridopsis denticulata is a clump-forming, winter-growing succulent from the arid west of southern Africa, grown for its plump, grey-green finger-like leaves edged with fine marginal teeth and its cheerful yellow daisy-like flowers. A vigorous member of the mesemb group in the family Aizoaceae, it spreads readily into low mounds of paired leaves and is one of the easier species in the genus Cheiridopsis for a beginner to keep.

Description

Cheiridopsis denticulata grows as a low, spreading clump of short branches, each bearing pairs of thick, boat-shaped to three-angled leaves. The leaves are firm, a soft grey-green to grey-blue often with a slightly bluish, waxy bloom, and carry small teeth (denticles) along their margins and keel — the feature that gives the species its name. New leaf pairs emerge from within the drying remains of the previous pair, a growth habit typical of the mesembs.

The flowers are daisy-like and usually yellow, though cream, orange, white and occasionally reddish forms occur; they open in the afternoon over the winter growing season and are pollinated by bees. Like other members of Aizoaceae they are not true daisies but produce many narrow petals from a succulent-based flower, and they close at night and in dull weather.

Distribution and habitat

The species is native to the winter-rainfall regions of the Northern Cape of South Africa, ranging north into southern Namibia around Lüderitz and south into the northern Western Cape, with its main concentration in Namaqualand. It grows on rocky, quartz-strewn or gravelly ground in open, exposed positions, enduring long, hot, rainless summers and receiving most of its moisture as winter rain and coastal fog. Plants often sit tucked among stones, which shade the roots and shed a little extra moisture their way.

Cultivation

Cheiridopsis denticulata is a rewarding, forgiving mesemb once its seasonal rhythm is understood. It is a winter grower: it does most of its growing and flowering through the cool months and rests in the heat of summer. Water it during autumn, winter and spring when temperatures are mild, letting the mix dry out between waterings, and keep it almost completely dry through the hottest part of summer to avoid rot. A very free-draining, mostly mineral mix in a pot with good drainage is essential.

Give it the brightest light you can — a sunny windowsill, greenhouse bench or protected spot outdoors in frost-free climates. In too little light the leaves become soft, over-long and pale, and the neat clumping habit is lost. See Watering and Repotting for general technique; established clumps are happy left snug and only need repotting every few years.

Propagation

The easiest methods are seed and division. Mature clumps can be lifted and split during the growing season, with each rooted division potted up separately; see Propagation — offsets. Seed is sown on a gritty, mineral surface and kept lightly moist in the cool season, germinating readily for such an accommodating genus — see Propagation — seed. Cuttings of individual branches can also be rooted, though division is usually simpler.

Common problems

Rot — the main risk, almost always from watering during summer dormancy or from a slow-draining mix; the plant softens and collapses at the base.
Etiolation — too little light produces stretched, floppy, pale leaves and a loss of the compact form.
Pests — mealybugs (white fluff between the leaves and at the roots) and, less often, root mealybugs are the usual culprits; see Pests and diseases.
