Cinta, what a great find from Lowes, that is a really nice Prayer Plant (Maranta leuconeura)
You should add photos of your plant to the database!
My luck with keeping both Maranta and Calathaea (same family) alive over the years has been hit and miss. I've had a Calathea on my screened porch for a few years that looks really ragged all the time but another one I sat out in deep shade amid shrubs about 3 years ago it looks really great! I just never see that one unless I go looking for it because it's totally hidden amid the trees and shrubs. It gets watered twice a week when the irrigation system is on and loves our high humidity here in Florida. I had one years ago that I left out on the back porch for a long time hoping that it was just dormant and that the rhizomes would produce new growth but it ended up getting dumped when we moved.
As Christine stated, the important thing is to never let it dry out completely. You don't want it sitting in water but the soil should be kept moist at all times.
