Why are my Peace Lily’s flowers turning green?

The Peace Lily (Spathiphyllum) is famous for its beautiful white blooms and lush green foliage, making it a favored houseplant among enthusiasts. However, noticing that your Peace Lily's flowers are turning green can be a cause for concern. Let's explore why this happens and how you can help your plant thrive.
Reasons for Green Flowers in Peace Liles
1. **Maturity of the Blooms**: As Peace Lily flowers age, they may transition from white to green. This natural process signifies that the flowers are maturing. If the flowers have maintained their bright white color for a good duration, expect them to take on a green hue as they approach the end of their life cycle.
2. **Insufficient Light**: Peace Lilies thrive in bright, indirect light. If your plant is in a low-light environment, it may affect the blooms' colors. Flowers can lose their vibrant coloration and turn green due to inadequate light for photosynthesis. If this happens, try moving your plant to a spot where it can receive indirect sunlight.
3. **Overwatering**: Overwatering can cause stress to your Peace Lily, leading to changes in the plant's overall health, including its flowers. Ensure that you're allowing the soil to dry out slightly between waterings, as waterlogged roots can result in stress and consequently, green flowers.
4. **Nutrient Deficiencies**: Peace Lilies require balanced nutrition to produce vibrant flowers. If your plant isn't getting enough nutrients, especially potassium, you may notice that its flowers lack color. Feeding your plant with a balanced, water-soluble fertilizer every few months during the growing season can help maintain its health.
5. **Temperature Fluctuations**: Peace Lilies thrive in temperatures between 65°F and 85°F (18°C - 29°C). Extreme temperature changes, either too hot or too cold, can lead the flowers to change color as the plant might be responding to environmental stress. Make sure to keep the plant away from drafts, heaters, or air conditioning vents.
Ways to Care for Your Peace Lily
To maintain the health of your Peace Lily and promote vibrant flowers, consider the following care tips:
- Light: Aim for bright, indirect light. Avoid direct sunlight, which can scorch the leaves.
- Water: Check the top inch of soil; if it feels dry, it's time to water. Typically, watering once a week should suffice.
- Humidity: Peace Lilies enjoy higher humidity. If your home is dry, consider misting the leaves or using a humidity tray.
- Temperature: Keep your plant in an environment with stable temperatures, ideally between 65°F and 85°F.
- Fertilization: Fertilize every 6-8 weeks during the growing season (spring and summer) with a balanced houseplant fertilizer.
In Conclusion
Seeing your Peace Lily's flowers turn green can indicate a variety of factors, from natural aging to environmental conditions. By monitoring your plant's light, water, and nutrient needs, you can help ensure that your Peace Lily remains healthy and produces beautiful blooms. If your flowers are still green but the plant otherwise appears healthy, you may simply be witnessing the natural aging process. Happy gardening!
