Mcrwt644, congrats on your new discounted plants. Chances are that the rhizomes will have enough life left in them to return to health once you have them in decent growing conditions. I would suggest that since they are already stressed from neglect that you go ahead and transplant them into a larger (at least 6" pot) with a 50/50% peat and sand mix. That way, once they start growing they won't have to be disturbed again for a couple of years or more. Be careful of the sand labeled "play sand" as it is usually very alkaline. If at all possible, use silica sand.
One more thing, Lowe's and Home Dispute have a 1 year guarantee on all of their plants. Keep your receipt and take advantage of it in case the plant croaks.
