It looks like months ago I grafted one upside down to the normal leaf/node direction of the graft. It is interesting to see that it took and seems to be doing fine...
I thought some might like to see this in case they accidentally graft one upside down, they might want to just let it stay & see if it takes...
Am I 100% with 1 for 1 reverse nodal direction grafting... Doubtful ... But it is amusing and the first that I know I have accidentally grafted in reverse direction...
