The peace plant flower, more commonly known as peace lily or Spathiphyllum, features dark-green leaves and fragrant white flowers borne even in low light. Popular as a house plant in the United States, the peace plant tolerates a wide range of growing conditions and typically has few problems with pests or diseases. Warm temperatures, such as those found in a typical home, suit the peace lily just fine, though the plant will not tolerate cold drafts. Numerous peace plant varieties exists, but all types share the same minimal care requirements to grow and flower indoors.
Keep your peace plant in a location that receives bright, filtered light throughout the day, such as a south-facing window. Maintain a temperature of 68 to 85 degrees F during the day and 58 to 75 degrees at night.
Clean the plant's foliage once every two or three days to remove dust, debris and any colonizing pests. Use a damp, clean cloth to wipe each leaf thoroughly, and always use room-temperature water to avoid shocking the plant.
Water the peace plant once every 7 to 10 days, allowing the soil to dry out somewhat between applications. Soak the soil thoroughly at each watering, wait several minutes, and then drain away any excess water from the tray.
Feed once every two to three months using a complete 20-20-20 NPK houseplant fertilizer. Water the plant lightly before and after fertilizing to release the nutrients into the soil and prevent injuring the plant's roots. Refer to the manufacturer's directions for proper dosage.
Repot peace plant every three to four years, or whenever the plant has outgrown its container. Increase the size of the new pot by 3 to 5 inches to provide plenty of room for the roots to expand. Use a fresh, moist potting soil to ease the transplanting process.
