Corpuscularia lehmannii, long sold under the name Delosperma lehmannii, is a slow-growing dwarf succulent from the Eastern Cape of South Africa, belonging to the ice-plant family (Aizoaceae). Its chunky, three-angled blue-green leaves stack in tidy opposite rows along short stems, giving the plant a sculptural, architectural look that suits small pots and dish gardens.
Well adapted to bright, dry conditions, it thrives on Indian balconies, sunny windowsills and terrace rockeries where drainage is sharp and watering is restrained. In strong light the leaf tips and edges can flush pink to bronze. Mature clumps occasionally produce small yellow daisy-like flowers in the cooler, brighter months.

Care guide
| Sunlight |
Bright light; 3-5 hours of direct morning sun outdoors, or a bright sunny windowsill indoors. Avoid harsh afternoon summer sun. |
| Watering |
Low. Soak only when the soil is fully dry; water sparingly in monsoon and winter. Never let the pot stand in water. |
| Soil / mix |
Very fast-draining gritty succulent/cactus mix; add sand, perlite or coco-cinder. Use pots with drainage holes. |
| Temperature |
Comfortable at 15-32 C; protect below 5 C as it is not frost-hardy. |
| Humidity |
Low humidity preferred; tolerates dry indoor air. Dislikes prolonged dampness. |
| Fertilizer |
Light feeder. A dilute low-nitrogen succulent fertilizer once in spring and once post-monsoon is enough. |
| Pruning |
Minimal. Remove shrivelled or dead leaves; trim leggy stems to keep the clump compact. |
| Repotting |
Every 2-3 years or when crowded, into a slightly larger pot with fresh gritty mix; best done in spring. |
| Propagation |
Easy from stem or leaf cuttings, or by dividing clumps; let cuttings callus 1-2 days before planting in dry gritty mix. |
| Pests & problems |
Generally trouble-free; watch for mealybugs and root rot caused by overwatering and poor drainage. |
| Toxicity / safety |
Generally considered non-toxic to pets and humans, but not intended for consumption. |

Growing tips
<p>During the harsh summer months (Apr-Jun), shift to bright shade or filtered light to avoid leaf scorch, and water only when the mix is bone dry.</p><p>In the monsoon (Jul-Sep) move pots under cover and cut back watering sharply, as excess moisture is the main cause of rot in Indian conditions. The cool, bright winter (Nov-Feb) is the best growing and flowering season give it full sun and resume light feeding.</p>
