Aww can't wait to see your grafting bloom.
But that is definitely a successful graft.
I have to redo a few of my grafts. The green part didn't make it, the tip that I grafted with flat graft using super glue seems to be okay. The mature (greyish ones are okay).
I tried to match the sizes of scions to the base of my flat grafts. I will redo this weekend. Good thing I left the stems longer from the base.
