The dominant vegetation displayed is succulent karoo, with members of the Mesembryanthemaceae prominent. The bababoudjies (Argyroderma) are prominent dwarf compact plants resembling pebbles and have been planted throughout on the white quartz. Their silver-green or gray leaves reflect the sunlight. Argyroderma (argyros = silver and derma = skin) have attractive purple or yellow flowers during the autum and winter. Their fruiting capsules like all other members of the Mesembryanthemaceae are hygrochastical, only opening with moisture. The velocity of raindrops on the wet capsule roofs disperses the seed by water pressure, almost like a water pistol. When the capsule dries out the lids close, protecting the seed. The seed are thus only released during the rainy season.
The Conophytum calculus looks like a cluster of gray marbles. This remarkable plant becomes dormant during the long dry summers. Yellow flowers appear in autumn. Other dwarf mesembs include Oophytum nanus, O. oviforme and Diplosoma insignis. The stonecrop family (Crassulaceae) is also well represented here with members such as the spekboom (Tylecodon paniculatus), the shrubby Crassula macowanii and dwarf Crassula columnaris.
