So this is it currently:
It's a morning glory scarlet o'hara.
I pinched the stem when I was moving it on the 12th (of this month):

As you can see it was very wilty and definitely would of died.
So I cut above the damaged part of the stem (which wasn't a whole lot) and dipped it in powdered root growth hormone.
Currently it looks good like it is growing as you can see a new 3rd leaf appeared and a 4th one is growing too (though still very very small)
I'm worried though that it isn't growing roots though and is just um sucking up water and growing with what energy is left in it until it finally dies.
Does anyone have any experience with this or even thoughts and opinions?
I keep the little pot in water and a plastic bag over the plant but not zipped closed just so it can keep humid.
