Red peace lilies offer a vibrant twist on a popular houseplant, known for their striking colored “blooms.” Unlike the common white peace lily, these varieties display hues from deep burgundy to bright red, adding a unique aesthetic to indoor spaces.
Understanding Red Peace Lilies
The striking red or burgundy color of a red peace lily comes from its spathe, a modified leaf surrounding the true, small flowers on the central spike (spadix). Often mistaken for petals, these spathes protect the plant’s inconspicuous flowers. Specific Spathiphyllum varieties, such as ‘Sweet Chico’ and ‘Red’, have been cultivated for this distinct coloration. These naturally red varieties differ from artificially dyed peace lilies sometimes seen in the market. Dyed plants have an unnatural, uniform color and may lose vibrancy, while true red varieties consistently produce colored spathes as they mature.
Red Peace Lily Care
Red peace lilies, like their white counterparts, are native to tropical rainforests and thrive when their indoor environment mimics these conditions. Providing consistent care tailored to their needs will encourage healthy growth and vibrant spathe production.
Light
Red peace lilies flourish in bright, indirect light, which encourages optimal growth and maintains spathe color. Ideal placement is near a north- or east-facing window, providing sufficient light without harsh direct sun. Direct sunlight can scorch leaves, causing yellowing or browning, and fade spathe color. While they tolerate lower light, insufficient light reduces flowering and vibrant coloration.
Watering
Proper watering is important for red peace lilies, which prefer consistently moist soil but are sensitive to overwatering. Allow the top inch or two of soil to dry before rewatering thoroughly. Underwatering causes drooping leaves, while overwatering leads to yellowing leaves, dark spots, and root rot. Good pot drainage is essential to prevent water from sitting around the roots.
Soil
A well-draining potting mix is suitable for red peace lilies, preventing waterlogging while retaining moisture. A good mix includes components like coir, perlite, or orchid bark to improve aeration and drainage.
Temperature and Humidity
Red peace lilies thrive in warm environments, ideally between 18°C and 29°C (65°F and 85°F). Keep them away from cold drafts and extreme temperature fluctuations. As tropical plants, they benefit from high humidity (40-60%). To increase humidity, mist leaves regularly or place the pot on a pebble tray filled with water, ensuring roots are not submerged.
Fertilizing
Red peace lilies benefit from regular feeding during their active growing season (spring and summer). A balanced liquid fertilizer (e.g., 20-20-20 or 10-10-10 NPK), diluted to half or quarter strength, is recommended. Fertilize every two to four weeks during this period, reducing frequency in winter. Avoid over-fertilizing, which can cause brown leaf tips and root damage.
Common Issues and Solutions
Even with proper care, red peace lilies can encounter some common problems. Recognizing the symptoms and implementing timely solutions can help maintain their health and appearance.
Losing Red Color
If a red peace lily’s spathe fades or turns green, it often relates to light or plant maturity. Insufficient light diminishes red pigment, as the plant lacks energy for vibrant color. Moving it to a brighter, indirect light spot can restore the hue. Over-fertilizing, especially with high nitrogen, also contributes to greener spathes by promoting leaf growth over flower development.
Leaves Turning Yellow or Brown
Yellowing or browning leaves on a red peace lily often indicate improper watering. Both overwatering (leading to root rot) and underwatering (causing drought stress) can discolor foliage. Low humidity causes brown, crispy leaf tips. Other factors include nutrient deficiencies, excessive direct sunlight, or natural aging. Adjusting watering, increasing humidity, ensuring proper light, and balanced fertilization can address these issues.
Pests
Red peace lilies are susceptible to common houseplant pests like spider mites, mealybugs, and aphids. These pests damage plants by feeding on sap, causing stunted growth, distorted leaves, or sticky residue. Regular inspection, especially of leaf undersides, aids early detection. For control, gently wipe leaves with a damp cloth or use organic methods like insecticidal soap to manage infestations.
Buying and Placement Tips
When acquiring a red peace lily, inspect the plant to ensure it’s a true red variety, not a dyed one. True red peace lilies have a consistent, natural red or burgundy color in their spathes, without artificial coloring on leaves or soil. Look for healthy, glossy green foliage and firm stems, avoiding yellowing leaves or pest signs. For optimal placement, choose a spot with bright, indirect light and consistent temperatures, away from drafts or direct heat sources. Areas with higher humidity, like bathrooms or kitchens, are also good choices.
