This is a variegated form of the Cotyledon ladismithiensis.
It can make a nice low succulent shrublet in the garden, does well in containers, and makes a good houseplant. It is widely grown and not difficult to cultivate. They are dormant in summer and thrive with bright light and ample airflow.
Watering needs: It is a very dry-tolerant plant. Water regularly in the growing season but avoid water-logging and let dry between waterings. Water with caution in winter, as the plant can lose its roots if the soil stays cold and wet for extended periods. If grown in a container, bottom watering by immersing the container is recommended. It must have very dry atmosphere.
Sun exposure: Does well in filtered sun, but can handle some shade, too. In shade the leaves color will remain greener, while in full sun conditions the foliage can develop a pale yellowish tinge. In summer keep cool and provide shelter from direct sun during the hottest hours. It can be sunburned if moved from shade/greenhouse into full sun too quickly. It tends to get really leggy in deep shade.
Frost tolerance: Protect from frost to prevent scarring. It requires a minimum temperature of about 5°C.
