It didn't leave any rooted stems or leaves?
Ahh, I just looked it up, it is one of the S. makinoi sedum.
Have you tried Limelight? I see my one small pot is alive and seems to be well. It goes semi-dormant here.
Winter of 2011/12, my first winter with it.
Here it is this last Nov. after rain and cold. Already starting to go semi-dormant. They really need good drainage to stay healthy. I was out looking at it a couple of days ago, it is looking good, I can see tons of little rosette tucked down just waiting for warmer weather.
