My Spathiphylllum made that recovery, I was away for more than 2 months in 2011 and my hubby mistakenly took it outside during our summer heat wave thinking it needs more sun. Did not understand it needs more shade. When I returned I quickly put it in shade and kept watering, keeping it moist and eventually came back.
My flapjack always gets the bad end of cold weather during our winters, especially if it rains often:
But given time to return to warm and dry temps..it makes complete recovery:
