Light
Filtered Sun
Provide at least 4-5 hours of filtered sun daily; low light levels lead to unsightly stretching (etiolation).

Leslie's Living Stone
Lithops lesliei is a stemless, clump-forming succulent perennial belonging to the family Aizoaceae. Characterized by two extremely fleshy, partially fused leaves with a flat top face, this species features intricate window-like markings in shades of brown, grey, and green that allow light to penetrate the internal tissues. In its natural habitat, the plant mimics surrounding pebbles to camouflage itself from herbivores. It produces daisy-like yellow flowers in autumn and undergoes an annual leaf renewal cycle where old leaf pairs wither to be replaced by new ones.
Watering
Measured
Never water while the plant is splitting and absorbing its old leaves, or rot will occur.
Soil
80% mineral grit (pumice, lava rock, river sand, zeolite), 20% peat moss
Use a grit-dominant mix composed of pumice, lava rock, and coarse sand with less than 20% organic matter.
Safety
Contact/Ingestion Risk
Entirely non-toxic to pets, including cats and dogs.
Difficulty
Moderate
Classified as moderate difficulty due to the strict watering discipline required.
Native Habitat
South Africa, Botswana
Lithops lesliei is native to the arid interior regions of South Africa and parts of Botswana. It thrives in rocky grasslands, growing semi-submerged among quartz, shale, and sandstone pebbles.
Frequently Asked Questions
Why is my living stone stretching upwards?
This is called etiolation, caused by insufficient light. The plant stretches upward seeking more sunlight. Gradually move it to a brighter location to maintain its compact shape.
Should I water during the splitting process?
No, watering must be completely suspended while the plant is splitting. The emerging inner leaves absorb all the water they need from the shriveling outer leaves.
What is the ideal soil mix for Lithops?
Standard potting soils retain moisture for too long. An ideal mix consists of 80% inorganic grit (pumice, lava rock, coarse sand) and 20% peat moss.
When does flowering occur?
Mature specimens typically bloom in early autumn, producing yellow daisy-like flowers directly from the center fissure.
My cat bit my living stone, is it toxic?
No, Lithops species are non-toxic to cats, dogs, and humans.
