About this plant

Conophytum is a succulent native to South Africa, instantly recognizable by its distinctive form—two leaves fused together into a single, compact body. Often called "living stones," these plants have a wonderful ability to blend in with their stony surroundings. They produce delicate flowers in autumn and winter, and go dormant during the summer months.

Placement & environment

Year-round, Conophytum thrives in a bright, well-ventilated spot. In spring and autumn, aim for partial shade outdoors; during summer, provide about 50% shade; and in winter, a sunny windowsill where it catches daytime light is ideal. These plants are cold-hardy and can survive winter as long as temperatures stay above 5°C (41°F). They prefer low humidity.

Seasonal watering rhythm

Light and temperature change a plant's metabolism, so the ideal cadence shifts with the seasons.

Watering rhythm

The key to Conophytum care is respecting its summer dormancy—water sparingly during these months. A helpful guide: wait several days after the soil surface dries out, and watch for the leaves to begin wrinkling slightly; that's your signal to water. As growth resumes in autumn, gradually increase watering frequency, though stay modest with winter watering. These plants dislike being constantly moist.

Common troubles

Quick lookup from symptom to likely cause and action.

SymptomLikely causeWhat to try
Leaves look wilted and have lost their plump appearanceOverwatering during summer dormancy or prolonged exposure to heat and humidityCut back on water during summer and ensure good air circulation around the plant. Remove any rotted portions and repot into fresh, dry soil to encourage recovery.
Leaves have shriveled and turned blackExcessive watering in winter or root rot preventing the plant from absorbing waterCheck the roots and remove any that are soft or blackened, then repot in fresh soil. Be especially conservative with winter watering going forward.
Brown spots appear on the leavesFungal issues from high humidity, or early signs of root rotRemove the affected parts and improve air circulation. Repot into fresh soil and reduce watering frequency at the same time.
Leaves feel sticky and insects are visible on the surfaceScale insects or spider mites, often triggered by crowding plants together in dry conditionsRemove affected leaves and rinse the plant with water, or carefully wipe down with a cotton swab. Use an insecticide if needed and improve spacing and ventilation to prevent recurrence.
Flowers don't appear, or buds drop before openingInsufficient winter dormancy, or a combination of low light and temperatures that are too warmGive your Conophytum a proper cool rest from autumn through winter—aim for around 10°C (50°F)—while still providing plenty of light. A true dormancy period is essential for encouraging flowers.
