Spathiphyllum wallisii - 6" pot
Of all the flowering house plants, Peace Lily care is probably the easiest. In fact, it tolerates average indoor conditions better than many houseplants. Plants that fail to bloom usually aren't getting enough sunlight. Move your plant to a brighter location, but keep it out of direct sun, which can scorch leaves. Got an older plant that refuses to bloom? If you haven't divided it in several years, divide it in spring. This is one of the few plants I know that blooms better after dividing it.
