The flowers do look very similar, I've noticed that between many differently named adeniums. Add to that the normal variation you get between flowers and different bloom times... I'm at the point of calling them whatever you want!
The green leaves are a bit larger, and this is the largest they've ever been since I got Chai Lai. They'd usually dry up and fall off when very tiny. The other branch still seems like it's trying, but nothing more than the little red bump still. I'm tempted to cut that one branch a bit lower while it's indoors for the winter and zero chance of it getting rot from the cut.
I don't think there are any roots yet, but the caudex is hard, ends are nice and dried up, no visible rot anywhere at least. I've watered it maybe twice since I repotted it and will be getting water once a month with the other 2 from now until spring, probably less often than that since it has zero roots.
Any suggestions from anyone to help this one along would be very helpful.
