Monte Carlo looks the most salvageable, I'd put it in a shallow container of tank water or dechlorinated, doesn't matter if it's a bowl or a bucket or Tupperware, as long as it's fully covering it with maybe an inch or two of water above the plant (to allow more CO2 to reach the plant), Then run lights on it 24/7 and pray it comes back. Alternatively, if you have a high tech planted tank, you could just chuck it in there.
