Aizoaceae is a family of flowering succulent plants found primarily in South Africa. This intriguing family of plants is a popular source of exotic plants for desert rock gardens.
I realy enjoy the unique shapes of the living stones and the bright flowers of the ice plant. I am a bit hesitant to encourage importing exotics.
Interestingly, the cactus is a succulent similar to the ice plant. The cactus behaves as an invasive when imported to the old world.
