Thanks so much for the reply akrouus.
I rooted in plastic cups with sterilized coco peat.This VdB had some roots,but the cup was not filled by any means.I was getting really concerned,because time after time,I would see the cutting develop some minimal roots,and then leaf out and die,so as soon as I saw some roots,I potted it up to the 3 gal pot figuring I had this 1 last cutting,and might as well try it.Happily,it held it's own and finally threw out some leaves.This is what the plant has looked like for 2 months now.
I attached a couple of pics for everyone amusement.
