This is a mutated, irregular form of P. 'Scheideckeri'. It has curved leaves and sometimes even a bit of variegation.
Like most rosette succulents, this plant likes plenty of bright indirect light. Beware of harsh sunlight that may burn the leaves of the plant. Water sparingly all year, only when the bottom leaves become soft and wrinkly. When watering, completely saturate the soil. Remove any water from the rosette of the plant, as it can cause the plant to rot. Slightly frost tolerant, we recommend to bring it inside if nighttime temperatures fall below -4 degrees Celsius.
