Argyroderma is a genus consisting of over 50 species[2] of succulents in the iceplant family from South Africa.[3]
These distinctive plants are among those known as “living stones”, because their highly succulent, usually stemless, blue-green leaves occur at ground level and can resemble small stones. They form small clumps of a few or many paired, usually cylindrical to egg-shaped leaves that are cleft in the center. Each stem bears just 2 leaves per season but may produce offsets over the years. In some species the old leaves persist and form a short column on which new leaves develop. Solitary daisy-like flowers, usually white, yellow, or purple, appear in the cleft.[3]
The entire genus is naturally confined to a relatively small region in the far west of South Africa, known locally as the “Knersvlakte” area. This is a very arid region of winter-rainfall desert and rocky quartzite sands.
