It's the middle of winter but they show progress! It's incredible. They are beautiful (again a weirdness creeps up on me while calling these tiny little balls "beautiful"...)!
Fenestraria aurantiaca on January 2, 2011
I saw on the pictures that the last one's root is a little exposed (that was almost not visible with the naked eye) and I already set it a little deeper into the sand so that it won't dry out too fast.
Against the light you can see that they even have those windows already at the top of their leaves.
