Bill: I just did the same thing with some cutting a friend from NY gave me last year. I have kept then in soil, moist and warm. They stayed green for a few months, then slowly darkened to dead wood by this spring. Last week I went out and pulled them out of the soiled pots, as I was ready to throw them in the trash, I noticed a bunch of little white roots (look like fine hair) all over the bottom part of the stalks. I dug a hole in the corner of te garden and plopped them in there. We'll see if they make it or not, but I doubt it now. I would have thought after a year in the pot, that they would have just not taken root at all, as it turned out, they were just begining to.
