Peace lilies are attractive indoor foliage plants that also produce showy white flowers. They are one of the few foliage plants that will flower in low light.
Height / Spread
Most peace lilies grow between 1 to 4 feet tall and wide. The cultivar ‘Sensation’ can reach a height of 6 feet with an equal width.
Peace lilies are sturdy plants with glossy, dark green oval leaves that narrow to a point. The leaves rise directly from the soil. These plants also periodically produce lightly fragrant white flowers that resemble calla lilies. The long-lasting flowers start out pale green and slowly turn creamy white as they open.
Peace lily will flourish in almost any well-drained potting mix. Soil should be kept moist but not soggy. The soil should dry out between waterings. Excessive drying out can cause the plant to wilt and the leaves and edges to yellow. When watering, use water that is at room temperature.
Peace lily will survive low interior light but would prefer bright filtered light. Peace lily should not be placed in direct sun or it will sunburn.
These plants need very little fertilizer. If you fertilize, use a balanced, liquid houseplant fertilizer such as 20-20-20 every two to three months.
Peace lilies enjoy warm conditions between 68 and 85 ° F during the day and nighttime temperatures about 10 ° F cooler.
Peace lilies have wide leaves that accumulate dust. Wipe leaves regularly with a damp cloth to remove dust.

Peace lilies have few pest problems. Mealybugs are probably the most common insect indoors. Mites and scales can also be problems. Root and stem diseases are the most common problem and are usually associated with over- watering.
Peace lily is very sensitive to chilling temperatures. Injury varies with the temperature and length of exposure. Try to avoid temperatures below 60 ° F.
Magnesium deficiency can cause plants to become stunted. Leaf tissue between the veins may yellow while veins remain green. The edges of the leaves can turn brown by overfertilization or by excessive drying.
Lack of flowering usually occurs on plants that are less than a year old or that receive insufficient light.
