Double Dream Big Roots Broken branch

This branch broke off a mature flowering plant in September. The bottom portion of the branch had bud rot and this is the top portion. It grew big strong roots over the last few months. This is what remains. It is growing roots but no vegetation. I’m keeping it outdoor s currently. I will probably bring it in under a lamp soon. It’s an experiment to see if it will re- veg and mature after the trauma. I have sprayed it with triple dose organic insect and disease control every week or so. I don’t give her anything but tap water right now.
