Why Are My Peace Lily Flowers Green Instead of White? And Why Do They Sometimes Smell Like Freshly Baked Bread?

Peace lilies (Spathiphyllum) are beloved for their elegant white blooms and lush green foliage. However, if you’ve noticed your peace lily flowers turning green instead of staying white, you’re not alone. This phenomenon can be both fascinating and perplexing. In this article, we’ll explore the reasons behind green peace lily flowers, delve into the science of plant pigmentation, and even touch on the curious connection between peace lilies and the aroma of freshly baked bread.


1. Natural Aging Process

One of the most common reasons peace lily flowers turn green is simply due to aging. The white “flowers” (which are actually modified leaves called spathes) naturally change color as they mature. Over time, the spathe may transition from bright white to a pale green or even a deeper green hue. This is a normal part of the plant’s life cycle and doesn’t indicate any health issues.


2. Light Exposure

Light plays a significant role in the coloration of peace lily flowers. Peace lilies thrive in indirect, low-to-medium light conditions. If your plant is exposed to too much direct sunlight, the spathes may produce more chlorophyll, causing them to turn green. Conversely, insufficient light can also lead to greenish blooms, as the plant struggles to photosynthesize efficiently.


3. Nutrient Imbalance

A lack of essential nutrients, particularly phosphorus, can affect the coloration of peace lily flowers. Phosphorus is crucial for flower development and pigmentation. If your plant isn’t receiving enough phosphorus, the spathes may lose their vibrant white color and take on a greenish tint. Consider using a balanced fertilizer to address this issue.


4. Genetic Factors

Some peace lily varieties are naturally predisposed to produce greenish spathes. Hybrid cultivars, in particular, may exhibit unique color variations. If your peace lily has always produced greenish flowers, it’s possible that genetics are at play rather than environmental factors.


5. Temperature and Humidity

Peace lilies are tropical plants that prefer warm, humid environments. Extreme temperature fluctuations or low humidity levels can stress the plant, potentially affecting the color of its flowers. Maintaining a consistent environment can help preserve the white coloration of the spathes.


6. The Curious Case of Freshly Baked Bread

Now, let’s address the whimsical question: why do peace lilies sometimes smell like freshly baked bread? While peace lilies are not typically known for their fragrance, certain environmental conditions or microbial activity in the soil can produce subtle, bread-like aromas. This phenomenon is rare but not unheard of, adding an extra layer of intrigue to these already fascinating plants.


7. How to Encourage White Flowers

If you prefer your peace lily flowers to remain white, here are a few tips:

  • Adjust Light Levels: Ensure your plant receives bright, indirect light without direct sun exposure.
  • Fertilize Regularly: Use a balanced fertilizer to provide essential nutrients, especially phosphorus.
  • Monitor Watering: Keep the soil consistently moist but not waterlogged.
  • Maintain Humidity: Use a humidifier or place the plant on a pebble tray to increase humidity levels.

Frequently Asked Questions (FAQs)

Q1: Can I reverse the green coloration of my peace lily flowers? A: In some cases, adjusting light, nutrients, and care conditions can help restore the white color. However, if the green hue is due to aging or genetics, it may not be reversible.

Q2: Are green peace lily flowers harmful to the plant? A: No, green flowers are not harmful. They are simply a natural variation and do not indicate any health problems.

Q3: How often should I fertilize my peace lily? A: Fertilize your peace lily every 6-8 weeks during the growing season (spring and summer) and reduce feeding in the fall and winter.

Q4: Why does my peace lily smell like bread? A: This is likely due to microbial activity in the soil or specific environmental conditions. It’s a rare but harmless occurrence.

Q5: Can I propagate a peace lily with green flowers? A: Yes, you can propagate a peace lily regardless of flower color. Simply divide the plant at the roots and repot the sections.


In conclusion, green peace lily flowers are a fascinating aspect of this versatile plant. Whether due to aging, light exposure, or genetics, these color changes add to the plant’s charm. And while the aroma of freshly baked bread may remain a delightful mystery, it’s just one more reason to appreciate the unique quirks of the peace lily.
