Description
Conophytum chauviniae is a dwarf rock-like perennial leaf-succulent, often very small, forming fairly large mats or domes of small greyish-green bodies with nice pink or purple blooms.
Bodies (Paired leaves): Cuneate, bilobed, up to 35 mm long, 15 mm tall, pale green to bluish with red or purple lines, papillate, often transparent near fissure. The leaf-tips (lobes) are free and triangular in shape and keeled sometime with broad, arrowhead-shaped, deep red markings.
Flowers: Solitary with a prominent perianth tube, petals magenta.
Fruit: 4-chambered.
Origin and Habitat
Namaqualand, Western Cape, South Africa.
Habitat: It grows in crevices on granite shelves often under shrubs.
Cultivation and Propagation
It is a “winter” grower which is most active from late winter until later spring and heading for summer dormancy, but in favourable growing conditions it keeps going over the summer too and doesn’t need particular care. All the forms of Conophytum chauviniae have the advantage of ease of growth.
Soil: Requires good drainage as it it is prone to root rot. It can grows outdoor in sunny, dry, rock crevices (protection against winter wet is required) It can also be cultivated in alpine house, in poor, drained soil.
Watering: It requires 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.
Fertilization: Feed it once during the growing season with a fertilizer specifically formulated for cactus succulents (poor in nitrogen), including all micro nutrients and trace elements diluted to ½ the strength recommended on the label. It thrives in poor soils and need a limited supplies of fertilizer to avoid the plants developing excess vegetation, which is easily attacked by fungal diseases.
Exposure: Keep cool and shaded in summer, it needs full sun or light shade.
Temperature: Hardy to -2°C. Ensure a very good ventilation.
Repotting: Avoid to repot frequently. This plant may stay in the same pot for many years.
Uses: Container, rock garden.
Pests and diseases: It is vulnerable to mealybugs and rarely scale.
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. It is easily propagated by seed.
