Peace lilies (Spathiphyllum) are popular houseplants, known for their elegant white, sail-like modified leaves called spathes. While many seek a “red peace lily,” naturally vibrant red Spathiphyllum are uncommon. This article clarifies what people typically encounter when looking for a “red peace lily” and provides comprehensive care instructions for all peace lily varieties.
Understanding “Red” Peace Lilies
True, naturally vibrant red peace lilies (Spathiphyllum) are extremely rare. Most available varieties feature white or greenish-white spathes. The desire for a “red peace lily” often stems from misunderstanding or misidentification of other plants.
Anthurium plants are frequently mistaken for “red peace lilies” due to their similar structure, featuring a prominent, heart-shaped spathe. Anthurium spathes commonly come in vibrant red, pink, or orange, unlike the typical white of a Spathiphyllum. Visual differences include the Anthurium’s waxy spathe texture and more upright growth habit.
Another common scenario involves white peace lilies artificially dyed red through dye injection. This results in temporary coloration, which will eventually fade back to white as the plant produces new, undyed blooms. While some Spathiphyllum cultivars may exhibit subtle reddish-brown or bronze tints, these are not the bright red often imagined and are less vivid than Anthuriums or dyed plants.
Essential Peace Lily Care
Caring for peace lilies involves providing consistent conditions that mimic their native tropical forest floor environment. Proper light, watering, soil, temperature, humidity, and fertilization contribute to a thriving plant.
Light
Peace lilies thrive in bright, indirect light, which encourages abundant blooms. While they tolerate lower light, insufficient light hinders growth and reduces flower production, often leading them to behave more like a foliage plant. Direct sunlight should be avoided, as it can scorch leaves. Placing a peace lily near a north, northeast, or northwest-facing window is ideal.
Watering
Consistently moist soil is preferred by peace lilies, but it should never be waterlogged to prevent root rot. Water when the top inch or two of soil feels dry. Drooping leaves indicate thirst. Filtered, room-temperature water is beneficial, as peace lilies are sensitive to chemicals like fluoride in tap water, which can cause brown leaf tips.
Soil and Potting
A well-draining potting mix rich in organic matter is suitable for peace lilies. This mix retains moisture while draining excess water, preventing soggy conditions. Pots should always have drainage holes. Peace lilies prefer to be somewhat pot-bound; repotting is only necessary when the plant has significantly outgrown its container, typically every few years in spring.
Temperature and Humidity
As tropical plants, peace lilies prefer warm conditions, with ideal daytime temperatures ranging from 68 to 85 degrees Fahrenheit (20-29 degrees Celsius). Temperatures below 60 degrees Fahrenheit (15 degrees Celsius) can slow growth and damage leaves. High humidity is also beneficial. If indoor air is dry, placing the pot on a pebble tray filled with water (ensuring the pot doesn’t sit directly in water) or misting the leaves can increase humidity.
Fertilizing
During their active growing season, peace lilies benefit from regular fertilization. A balanced liquid fertilizer applied at one-quarter strength every six to eight weeks is sufficient. Over-fertilizing can lead to salt buildup in the soil, burning leaf tips and roots. Reduce or cease fertilization during winter months when growth slows.
Troubleshooting Common Peace Lily Issues
Peace lilies can exhibit signs of distress. Understanding common issues helps in addressing them.
Yellowing Leaves
Yellowing leaves can indicate overwatering or underwatering. Overwatering often leads to root rot. Underwatering also causes yellowing. Nutrient deficiencies or too much direct sunlight may also contribute.
Brown Leaf Tips
Brown leaf tips indicate low humidity or salt buildup from tap water minerals or excessive fertilizer. Inconsistent watering can also cause browning. Providing adequate humidity through misting or pebble trays and using filtered water helps prevent this.
No Blooms
Lack of blooms is often due to insufficient light. While peace lilies tolerate low light, brighter indirect light encourages blooming. Young plants may not be mature enough to flower. Improper fertilizing, like too much nitrogen, can also hinder blooms.
Pests
Peace lilies are generally pest-resistant, but spider mites and mealybugs can occasionally be an issue. They appear on the undersides of leaves or in leaf axils. Regular inspection and wiping leaves can deter infestations. If present, insecticidal soap or neem oil can manage the problem.
Choosing Your “Red” Peace Lily and Long-Term Care
When seeking a “red peace lily,” remember that true red Spathiphyllum are rare. What you find is likely an Anthurium or an artificially dyed white peace lily, whose color will fade. Regardless of color, the fundamental care principles for peace lilies remain consistent. Focus on providing suitable light, consistent moisture, appropriate soil, and adequate humidity to ensure your plant’s health and vigor. Appreciating the peace lily for its natural beauty, including its glossy green leaves and elegant white spathes, brings lasting enjoyment.
