You can keep them nice. They need bright, indirect light. Do not over water. Root rot can cause them to wilt so, you think they need water and give them more. Feel the soil before watering and do not let them stand in water. Feed them with a quality liquid or granular food on a regular basis.

peace lily blooms like crazy. I use those little green houseplant fertilizer sticks. It's blooming under a skylight, too. Guess that helps.
