Pine Cone Cactus

Succulents and cacti are both very odd and interesting the way they grow. Some take many years to grow, like the Saguaro which will not start branching out till it is around 50 years old. Where others some take only a few months. The photograph below of the Tephrocactus articulatus var. diadematus was taken on May 25th and the next photo was taken this afternoon. What is very interesting about this is the bottom plant is from the mother plant that I have had for about five years still looks the same, it has never branched out.
