Peace Lilies are one of the most common houseplants because they’re fairly easy to grow and beautiful, too!
Peace Lilies are tropical, evergreen plants that thrive on the forest floor, where they receive dappled sunlight and consistent moisture. Replicating these conditions in the home is the key to getting your peace lily to be happy and healthy.
With enough light, peace lilies produce white to off-white flowers starting in the early summer, blooming throughout the year in the right conditions.
Most household varieties of Peace Lily grow up to 16 inches tall, but larger outdoor cultivars can have leaves that reach up to 6 feet in height. Peace Lilies are not cold-hardy plants, so they can only be grown outdoors in warm, humid climates.
Can Peace Lilies be grown in water? Yes, Peace Lilies can grow in water alone; they are often sold in vases without any soil. Ideally, the base of the plant should be suspended above the waterline, either by a specially-made insert or a layer of small river stones. This allows the roots to grow into the water but keeps the base of the plant and its leaves from being constantly wet, which can cause rot.
How to Care for a Peace Lily?
- When it comes to watering, consistency is key. Keep the soil moist, but do not overwater. Peace Lilies can tolerate short periods of dry soil, but their leaves will start to brown if neglected for too long.
- Peace Lilies are sensitive to chemicals commonly found in tap water, such as fluoride, which may cause brown leaf tips. Use filtered, room-temperature water, if possible.
- Peace Lilies enjoy high humidity. Misting their leaves or placing their pot atop a moistened tray of gravel can help to increase humidity around the plant.
- Peace Lilies are not heavy feeders, so fertilize only occasionally. To encourage spring and summer growth, fertilize every 6 weeks or so with a balanced houseplant fertilizer starting in late winter.
- Peace Lilies are a tropical plant, so keep them in temperatures above 60°F (16°C) and away from cold, drafty windows. They do best in temperatures upwards of 70°F (21°C).
- Keep these plants out of direct afternoon sunlight but in a bright, well-lit area. An east-facing window is ideal, as they will be exposed to the bright morning sun but avoid the intensity of mid-day rays.
How to Get Peace Lilies to Flower?
- Most often, if no flowers are appearing, the plant is not getting enough light. Peace Lilies are very tolerant of low light, but low light doesn’t mean any light! To encourage flowering, move the plant to a brighter location, where it will receive bright, indirect light.
- Green flowers, weak-looking flowers, or a general lack of flowers can be caused by improper fertilizing. In the case of green flowers, cut back on fertilizing. In the case of weak-looking flowers or a lack of flowers, try switching to a fertilizer made for flowering plants. This type of fertilizer will have a higher amount of phosphorous, which plants need for blooming.
The Peace Lily is said to have gotten its common name from its white flowers, which rise timidly above its green foliage and resemble white flags of peace. Despite the peace lily’s common name, it is not related to true lilies.
The plant’s interesting blooms are also the source of its Latin name, Spathiphyllum, meaning «spathe-leaf». The flowers consist of the spathe (the white, sheath-like leaf) and the spadix (the spike of small flowers located within the spathe).
