The third of my Living Stones (Lithops) has burst into flower.
They spent several days like this (two plants in this pot):
Then, finally, today they opened fully:
I've noticed with all which have flowered so far that they only open fully after they have been in full Sunlight for some hours, usually opening as the Sun goes past. To give an idea of size they are all in 2 inch (50mm) pots. I have quite a few smaller Lithops plants but I think they need to reach a decent size before they begin to flower.
Each plant is in two parts and the flower appears from the join. Those parts will begin to shrivel over the Winter. Then is the time to stop watering until new sections have grown and reached their full size / maturity.
