Cotyledon undulata superba, native to South Africa, has fleshy rounded leaves with wavy, ridged margins. Leaves are densely pruinose giving the appearance of being covered in white powdered sugar, and the edges are strongly undulated like the edge of a lasagna noodle. When blooming it has golden orange bell-shaped flowers. In habitat in Africa, Cotyledons usually grow in rocky quartz fields where they have excellent drainage provided by very porous soil, very bright light to full sun, and good air circulation. Water thoroughly when soil is dry to the touch. Water with caution in winter, as the plant can lose its roots if the soil stays cold and wet for extended periods. Summer dormant. Protect from frost to prevent scarring.
