Pleiospilos nelii is a dwarf, stemless succulent native to the semi‑arid regions of the Karoo in South Africa It typically forms two or four thick, fleshy leaves, often grey‑green to brown, with small dark spots and a deep central cleft—giving the appearance of a split stone, a camouflage adaptation in its habitat. A new pair of leaves grows from the center each year, absorbing the older leaves.
In cultivation, it remains compact. around 5–10 cm tall and up to 10 cm across, and produces relatively large daisy‑like flowers, typically yellow to orange, about 6–7 cm wide, that open in late winter to spring (or late summer/autumn in some regions), often in the afternoon, closing at night.
Native to:Southern Africa, specifically the semi‑arid Karoo region of South Africa. The plant is adapted to mimic local granite and rocky ground, aided by its mottled, grey‑green to brown hemispherical leaves and compact growth form.
Water:
Use a “soak and dry” method—allow the soil to fully dry before watering deeply. During the growing season (spring and autumn), water sparingly when leaves appear slightly shrivelled. In winter (dormant) and summer heat, reduce watering significantly or keep dry to mimic natural rhythms and prevent rot.
Light:
Provides bright filtered light or morning sun with protection from harsh midday rays. A south or west‑facing windowsill is ideal, delivering 3–4 hours of direct sun plus bright ambient light. Direct sunlight can scorch leaves, so avoid prolonged exposure.
Humidity:
Prefers low to moderate humidity. High humidity increases the risk of fungal issues and root rot, especially when paired with overwatering. I
Temperature:
Thrive in temperatures between roughly 16 °C and 27 °C (room temperature). It does not tolerate frost—keep above ~10 °C, and ideally around 15 °C or warmer, particularly if grown under glass. In the UK, growing under glass or indoors year‑round is advisable
