Answer: Since they are are actively growing, I would plant them in the pots so that the foliage is above the soil because burying it would be an invitation to rot. I think you may have dug them up too early in the fall -- usually the frost literally kills the tops all the way back and there is no life left in the foliage at all. These plants take a certain amount of cold so you are not risking killing them by leaving them out for a hard freeze. Then, they may have been kept either too warm or too damp -- when dormant they should be stored dry and cool (not freezing).
