At this time of the year I am always amazed at lithops and how they seem to love the hot weather and flourish with new plump growth. Our lithops started a few years ago with one plant only and every year they divide into 2 and double our stock.It is wonderful to watch this. At the end of their growing season their final finale is a gorgeous flower in the centre. Love it! We have some growing from seed this season but these wont be large enough to go out into the big bad world until next year.
One amazing characteristic is their ability to change colour to the same colour as the gravel surrounding it. The photo here shows just how close they get to the correct colour. Apparently(according to David Attenborough) this wonderful ability is an adaptation to help camouflage themselves from animals seeing them and eating them.
Who would have thought that was possible? Very clever indeed.
