Argyroderma subalbum, commonly called the split rock plant, is a small dichotomously branching succulent in the ice plant family, Aizoaceae. A. subalbum is native to South Africa near the northern and western cape. The stemless plant has two bluish gray ovoid leaves that shed each season from the cleavage. New sets of succulent leaves push up from the middle and replace older sets of leaves. Argyroderma subalbum is a singular to clustering plant that does not exceed more than 2 to 3 inches in width and 1 to 2 inches in height for each leaf set. A. subalbum blooms mid fall to winter time with small bright magenta flowers that have white centers and yellow anthers. This species is grown as an ornamental plant for its compact size and unique leaf shape. Argyroderma subalbum grows best in full sun to partial shade, sitting in well-draining soils. Water the plant adequately during winter and keep dry during the summer when leaves are withering and falling off. It is a drought-tolerant species and can tolerate a wide range of temperatures. Allow the soil to completely dry out in between waterings. USDA plant hardiness zones 9b to 11b.

Argyroderma subalbum seeds require consistent moisture and humidity to germinate, but the soil should not remain soaking wet. Cloning boxes, ziplock bags, and other containers that retain humidity are ideal to store sown pots. Use a well-draining sterilized soil mix. Seeds should be sown directly on top of the potting mixture and lightly covered with a thin layer of sand or potting mix, just enough to cover the seeds. Germinating pots should be kept indoors, out of extreme light and heat. Ideal germination temperatures range from 70°F to 80°F. Germination typically takes 1 to 3 weeks to occur. Even with optimal conditions, germination may be slow and sporadic.
