So here we are!  My little Crassula Arborescens is preggers with pups!  I’m so excited that today I found three separate leaf pups with their own root systems developed!  The whole process took about two weeks.  I didn’t know what would unfold since, I’ve never heard of this type of succulent propagation.  Certainly, the most common propagation method is taking a fresh young leaf cutting and sticking it in soil and keeping it in a moist but shaded environment.  These pups, however, just started growing on the plant’s leaves while still attached to the stem.  I have done lots of online research about this particular plant’s propagation but never one saw anything similar to what I was able to observe and photograph.  I could probably detach the pups with roots and plant them in soil right now, but I think I will wait for one more week to be safe.
