Lithops, often referred to as "living stones," are small, stemless succulents native to southern Africa, including regions of Namibia, South Africa, and Botswana. They have evolved to mimic the appearance of pebbles, a camouflage strategy that helps them avoid predation in their natural habitats. Each plant consists of a pair of thick, fleshy leaves that are partially buried in the soil, with a fissure at the top from which a daisy-like flower may emerge, typically in autumn.
These succulents are well-suited for indoor cultivation in the UK, provided their specific care requirements are met. Their compact size and unique appearance make them an intriguing addition to any plant collection.
Native to: Lithops species are indigenous to arid regions of southern Africa, including Namibia, South Africa, and Botswana. They are commonly found in dry grasslands, rocky terrains, and areas with minimal rainfall, often blending seamlessly with the surrounding stones.
Water: Lithops require minimal watering and are highly susceptible to overwatering. You must not water them during moulting until the old leaves are completely dried. During their active growth periods in spring and summer, water sparingly only when the soil is completely dry and the weather is sunny. Avoid watering during long cloudy periods. In autumn and winter, when the plants are dormant, withhold watering entirely to prevent root rot.
Light: Provide Lithops with ample sunlight to maintain their compact form and vibrant coloration. A south-facing windowsill that receives at least 4–5 hours of direct sunlight daily is ideal. Insufficient light can lead to elongated growth and loss of characteristic patterns.
Humidity: These plants thrive in low-humidity environments, reflecting their desert origins. Ensure good air circulation and avoid placing them in humid areas such as bathrooms.
Temperature: Lithops prefer temperatures between 18°C and 24°C during their growing seasons. They can tolerate cooler temperatures down to 10°C during dormancy but should be protected from frost and sudden temperature fluctuations.
