It is natural for the peace lily’s spathe—the leaf-like wrapping that surrounds the small flowers—to be green as it develops. In its normal cycle, the spathe starts and ends green, turning brilliant white mid-season. That is probably what you are seeing. But if you feel like it is more than just that, there are a few things you can do to bring out the brighter whites. The peace lily needs minimal fertilizer, so houseplant fertilizer should be used at half strength, only once or twice a year. The peace lily thrives in bright, but indirect, light and in moist but well-drained soil.
