Some of my Lithops (Living Stones) plants are coming into bloom again:
The flowers normally only open while direct Sunlight reaches them. They had been trying to flower for a few days but hadn't opened even in direct Sunlight. It would appear they also need a decent daytime temperature. The ambient temperature had been fairly low with mainly overcast skies and just a few bursts of direct Sunlight. They live in a propagation tray which I leave uncovered during the Summer. I put the cover back and the temperature quickly rose and the flowers opened.
