Peace Lilies (Spathiphyllum) are popular houseplants, often recognized for their deep green foliage and distinct white, flag-like blooms. These elegant plants bring a touch of tranquility to indoor spaces and are widely appreciated for their beauty. However, confusion often arises with the term “red peace lily,” as true Peace Lilies do not naturally produce red flowers.
The Truth About Red Peace Lilies
The notion of a “red peace lily” typically stems from two main possibilities: artificial dyeing or misidentification. White Peace Lilies are sometimes subjected to artificial coloring processes to achieve a red hue. This is typically done through stem injection, causing the white spathes to temporarily turn red. This red color is not permanent and will fade over time, reverting to the plant’s natural white or cream coloration with new blooms.
Another reason for the “red peace lily” designation is confusion with other plants that naturally produce red, spathe-like structures. The most common example is the Anthurium, often called a “red peace lily” due to its brightly colored, heart-shaped bracts that resemble Peace Lily spathes. Though in the same plant family (Araceae), Anthuriums are a different genus (Anthurium). Their waxy flowers come in various shades of red, pink, or white, unlike the delicate white blooms of a true Peace Lily. While extremely rare or newly developed hybrid Spathiphyllum varieties with genuine red coloration might exist, they are not widely available.
Essential Care for Your Peace Lily
Caring for a Peace Lily involves providing consistent conditions that mimic its native tropical environment. These forgiving plants are suitable for many indoor gardeners, and observing their cues is often more effective than a strict schedule.
Light
Peace Lilies thrive in bright, indirect light for robust growth and white blooms. Placing them near a north or east-facing window is often ideal, providing filtered sunlight without direct intensity. Direct sunlight can scorch the leaves, causing brown spots or yellowing. They tolerate lower light but may produce fewer flowers or grow slower.
Watering
Peace Lilies prefer consistently moist soil but should not be left in soggy conditions, as this can lead to root rot. Water when the top inch or two of soil feels dry. A dramatic wilt indicates the plant needs water. Ensure water drains thoroughly from the pot bottom, discarding excess from the saucer to prevent standing water. Filtered or room-temperature water is beneficial, as Peace Lilies are sensitive to chemicals like fluoride and chlorine in tap water, which can cause brown leaf tips.
Humidity and Temperature
Originating from tropical rainforests, Peace Lilies thrive in warm, humid environments. Ideal temperatures are 65°F to 85°F (18°C to 29°C) during the day. They are sensitive to cold drafts and temperatures below 60°F (15°C), causing leaf damage and stress. To increase humidity in dry indoor environments, group plants, use a pebble tray, or place a humidifier nearby.
Soil and Fertilizing
A well-draining potting mix, mimicking rich forest floor soil, is suitable. A general houseplant mix with added perlite or orchid bark for drainage works well. They are not heavy feeders; over-fertilization can cause leaf burn or brown tips. During the spring and summer growing season, apply a balanced liquid fertilizer diluted to half strength every 4 to 8 weeks. Fertilization is not necessary during fall and winter when growth slows.
Addressing Common Red Peace Lily Concerns
Peace Lily owners may encounter common issues, especially if the plant was a “red” variety. If the plant was artificially dyed, its color will fade as new, natural white blooms appear.
Wilting or drooping leaves indicate a Peace Lily needs attention. This usually indicates insufficient watering, but overwatering can also cause wilting by leading to root rot. Temperature shock, like cold drafts, can also cause drooping. Yellowing leaves often signal overwatering, nutrient deficiencies, or too much direct sunlight. Older leaves may also naturally yellow with age.
Brown leaf tips or edges commonly result from low humidity, inconsistent watering, or fluoride/chlorine in tap water. Addressing humidity and water quality can help. If a healthy Peace Lily isn’t blooming, insufficient light, lack of fertilizer, or immaturity can be factors. Adequate bright, indirect light and consistent, balanced fertilization during the growing season encourage flowering. Pests like spider mites or mealybugs can affect Peace Lilies, though they are resilient. Regular inspection and prompt treatment maintain health.
