Q.Zebra plant
I found this article maybe too late, but my zebra plant has lost all leaves and has died almost all the way down the stalk. Is there any way to save it? There looks like two new plants growing off to the side, is this possibly new zebra plants?
It's possible those are germinated seeds from the plant.
It does appear that your plant had died.
Here is a link to refresh you on the care requirements should you choose to try growing another Zebra Plant.
