G. depressum as species name suggests lies flat or prostate. The soft heavy leaves can be easily damaged or bruised, making them unsightly. In term of size, this is a giant relative to lithops. The leaves are about 3" long, flowers 1.2" across. All parts are bigger, the seed pods and even the seeds are bigger. I even managed to germinate few old seeds traps in a rotting seed capsule and nurse a seedling to about 2 cm with secondary leaves.
Will probably try to test grow different species from genus here next year. There are afterall a few species stretching from Little Karoo east into the summer rainfall area of Eastern Cape, South Africa.
