I've had it in water for 10 days. It's down to 1 leaf. doesn't look like it'll make it...

I know this is a bit late but for what it's worth, the stems are brittle and some animals like to eat them so I often end up with broken off bits. They root readily in shaded damp soil for me.

thanks! if it happens again, I'll try that.

They're related to to Purple Heart, Wandering Jew, etc., which are all easily propagated from cuttings.
