Why does it only have one leaf? My manyflower marshpennywort can only have one leaf at a time? It used to have 5 and 3 died then it grew 2 more then 4 died leaving it with one. It seems to be able to only have one leaf. Anyone know how to deal with this? The poor plant looks depressed. 😔 #ManyflowerMarshpennywort #WeirdPlants #PlantAddict #BeforeAndAfter
