Fittonia is a native of Peru and loves moisture and warm temperatures.
I did every thing you could do wrong with this plant and still it thrived. I think as long as you give it high humidity and don’t let the soil dry out it will forgive anything else you might do to it. I’ve grown this one almost entirely under the table lamp in the parlor. It is in a north facing room that has a covered porch outside the windows and so it is a very dark room, and the plant is not even near the window. This will make a great office plant.
It is in a bowl with out drainage and likes being wet. It will die if the soil dries. Be sure to check it daily. If you find your fittonia wilted you did not water it enough. Sometimes if you water it and keep up the watering it will come back to life for you. But the recommended method is to grow it in well drained soil and water frequently.
This is a fast growing plant, it has doubled in size in the month since we acquired it. It will only get to about 6″ tall, new growth is spreading. It also works very well in hanging baskets.
