This is an out of nowhere Bougainvillea dig that I did this afternoon. Basically in the photos you can see that it's got an alright curvy trunk, and a bit of a root spread, but as some of you may notice, that's because the darn thing is UPSIDE DOWN! The 'trunk' is actually the extending lower root that was under the ground, and the 'root spread' is the base of the branches that were above the ground.

So my question to anyone who might be able to help is, has an upside down planting ever been known to succeed? I plan to soak the girl in seasol for a couple days, and she doesn't have any roots to speak of so I know that this is going to be a rare chance she'll take.
I have a 2 year old bent branch cut from a bougy climbing a fence that struck and is thriving now, So I do know that a non-root wood bougy can strike roots.
thanks in advance everyone!
