Leaves are typically grey, often showing subtle tinges of other tones. The cultivar name 'Blue Moon' denotes the rugosa (wrinkled) texture on the leaf tops.

In the garden

Lithops schwantesii subsp. schwantesii var. rugosa 'Blue Moon' belongs to the genus Lithops in the Aizoaceae and carries the rugosa descriptor for its textured leaf tops. The plant shows irregular channels across the leaf surface and typically presents a grey colouring with occasional tinges; its compact habit makes it a specialist subject rather than a border plant. Flowering in the UK occurs from August to September, when yellow flowers appear from the central fissure. Keep the plant in a very bright spot with as much direct light as possible; good light preserves leaf colour and the rugose texture. Use a free-draining, gritty compost and a shallow pot so the bodies sit near the surface; avoid waterlogged conditions since prolonged wet at the roots leads to rot. Water sparingly and allow the substrate to dry between thoroughings, adjusting frequency to seasonal growth. In the UK, 'Blue Moon' suits glasshouse displays, alpine houses or a bright, sheltered windowsill where it can receive strong light and protection from persistent wet and cold. Its rugose leaf tops make it a distinct addition to a specialist Lithops collection and a useful reference plant when comparing textured cultivars.
