Argyoderma fissum is an extremely unique and beautiful succulent native to Knersvlakte near Vanrhynsdorp in the Western Cape Province in South Africa, and forms dense patches and camouflage with the white quartz gravel in its natural habitat. This is a miniature clump-forming perennial succulent attaining less than 20 cm of height and 30 cm or more of dimeter. With its bluish-green finger-like leaves, argyroderma fissum forms huge mats. The finger-like leaves and plant structure are quite different than the silver-grey spilt-egg plant body found in the other members of the genus. Leaves are reduced to a single pair, 5-10 cm long, 8-12 cm wide, half-cylindrical (sometimes cylindrical at the base), firm and highly succulent, rounded at the tip, flattened or convex on the upper side. Color is green, bluish green to whitish grey and usually reddish at the tip.
Flowers emerge in the summer from a fissure between the leaves and are beautiful, solitary, 30-40 cm in diameter, on a 4cm long stalk, magenta in color with a white center. But they can also be pink, yellow or red. They eventually turn into capsules, which burst open with each shower of rain. The seeds inside are very small and are dispersed in all directions by falling raindrops
Argyroderma fissum needs full sun. in the event of lack of light, its body gets thinner. However, it needs to keep cool and shaded in summer.
Argyroderma fissum is more forgiving than Lithops to excess watering (although it should be rarely given in summer). It also thrives in light winter rains in temperate climates. As such, it needs little water, or else its epidermis can break, causing unsightly scars. Water minimally in summer, only when the plant starts shrivelling.
Argyroderma fissum is quite cold resistant and hardy to -5-degree C (or less if dry), depending on the clone.
Argyroderma fissum can be propagated by seeds or division of larger clumps, although seeds is an easier option. Seeds germinate in 7-14 days at 21-degree C.
