Peace lilies are popular houseplants known for their attractive dark green leaves and elegant white flowers. However, sometimes these flowers may start to turn green, leaving caretakers puzzled and curious about the cause. In this article, we will explore various factors that contribute to the unexpected color change in peace lily flowers and provide helpful tips on how to address the issue.

One contributing factor to green peace lily blooms could be part of the natural aging process. As the flowers mature, they naturally transition from their pristine white hue to a more greenish shade. Another possible reason might be over-feeding the peace lilies with fertilizer. These plants have relatively low fertilizer needs, so giving them too much can lead to less striking flowers.

Besides the aging process and over-fertilization, factors like light levels may also impact the coloration of peace lily flowers. Ensuring the proper balance of sunlight exposure is crucial for well-being and appearance of your plants. Our discussion in the following sections will provide guidance on how to find the optimal growing conditions to keep your peace lily flowers looking their best.

Why Are My Peace Lily Flowers Green

How Peace Lilies Bloom

Peace lilies, scientifically known as Spathiphyllum, are popular houseplants known for their stunning white blooms. These plants produce modified leaves called spathes, which initially appear green. As they mature, the spathes turn white, creating the appearance of a flower. Once the blooms age or the plant undergoes certain environmental changes, these flowers may shift back to a green hue, which might concern some gardeners.

Factors Affecting Flower Color

  • Insufficient Light: One of the primary reasons Peace Lily flowers turn green is due to inadequate light. When Peace Lilies don’t receive enough light to photosynthesize properly, they start creating and shifting chlorophyll to maximize its utility. To prevent this, place your plant in an area that receives indirect sunlight.
  • Aging Blooms: As Peace Lily blooms age, they naturally develop a green hue. This is completely normal, and you can prune these older blooms at the base if desired.
  • Excessive Sunlight: Contrary to insufficient light, too much direct sunlight can also cause Peace Lily flowers to turn green. Excessive sun exposure triggers photosynthesis in the spathes, leading to a green coloration. To avoid this, keep your plant away from areas where it might receive harsh direct sunlight.
  • Improper Watering: Regular watering is crucial to maintain a Peace Lily’s health. Ensure that the soil is moist but not soggy, and provide proper drainage to avoid waterlogged conditions.
  • Temperature Fluctuations: Peace Lilies require a stable environment to thrive; fluctuations in temperature may cause the blooms to turn green. Keep your plant away from cold areas and extreme heat sources, such as radiators or vents.

Taking proper care of your Peace Lily will ensure that it produces beautiful white blooms. By providing optimal light, watering, and temperature conditions, you will be able to keep your plant happy and healthy, while enjoying its stunning foliage and flowers.

Environmental Causes

Light Conditions

One of the factors contributing to peace lily flowers turning green is the amount of light the plant receives. Peace lilies prefer indirect sunlight, which means positioning them near a window, but not in direct sunlight. When your peace lily isn’t getting enough light, it starts to produce more chlorophyll, which gives the plant and its flowers a green hue. To avoid green flowers, ensure your peace lily has sufficient access to indirect light.


Another element to consider when discussing peace lily flowers turning green is temperature. These plants usually prefer temperatures in the range of 65 to 85°F (18 to 30°C). If the temperature goes outside of this range, it can trigger environmental stress in the plant and cause the flowers to turn green. To maintain healthy flowers, keep your peace lily in a room with stable temperatures.


Lastly, humidity also plays a role in the appearance of peace lily flowers. These tropical plants are used to high humidity environments, so if the air in your home is too dry, it can contribute to green flowers. To improve humidity levels:

  • Mist the leaves regularly with water
  • Put a tray filled with water and pebbles underneath the pot
  • Use a humidity tray or a humidifier in the room

By addressing these environmental factors — light conditions, temperature, and humidity — you can keep your peace lily flowers looking healthy and vibrant, and prevent them from turning green.

Nutritional Factors


One possible reason for peace lily flowers turning green is the use of too much fertilizer. Excessive amounts of fertilizer can increase chlorophyll production, which causes the spathes to turn green, particularly if the fertilizer is rich in iron and nitrogen. To rectify this, consider reducing the amount of fertilizer you use and monitoring your peace lily’s reaction. If you suspect over-fertilization, you can also stop fertilizing your plant for a while to help it recover.

  • Signs of over-fertilization:
    • Green spathes
    • Leaf burn or yellowing
    • Stunted growth

Plant Supplements

Adding certain plant supplements to your peace lily’s care routine can help maintain healthy, white flowers. However, be cautious not to use too much or too frequently, as this can inadvertently cause the flowers to turn green.

As you provide the appropriate care for your peace lily, remember these other factors that contribute to its overall health:

  • Adequate lighting: Peace lilies thrive in indirect light, and too much sunlight may trigger photosynthesis in the spathes, causing them to turn green. Try placing your peace lily in a spot with indirect light for best results.
  • Proper watering: Water your peace lily regularly, but ensure that the drainage is adequate. Peace lilies prefer moist, but not soggy, soil conditions.
  • Temperature: Peace lilies enjoy a warm environment and should not be exposed to cold temperatures. Keep them away from drafts, radiators, and vents.

In conclusion, by regulating the amount of fertilizer and adjusting plant supplements, you can help maintain your peace lily’s beautiful, white flowers. Additionally, remember to provide your peace lily with proper lighting, watering, and temperature conditions to ensure its overall health and well-being.

Potential Solutions

Adjusting Light Conditions

One possible cause of peace lily flowers turning green is exposure to bright light. To avoid this, place your peace lily in an area with moderate, indirect sunlight. Peace lilies thrive in bright, indirect light; however, avoid direct sun, which can scorch the leaves and cause green blooms. Keep in mind that too little light can also impact the plant’s flowering. Smart Garden Guide offers more information about the relationship between light conditions and green peace lily blooms.

Managing Water Intake

Peace lilies should be watered consistently, but not excessively, as they don’t like soggy soil. Overwatering can cause various problems, including the development of green flowers. To ensure proper hydration, water your peace lily when the top inch or so of soil feels dry to the touch. Be sure to use a well-draining potting mix and a pot with drainage holes to prevent root rot and other waterlogging issues.

Balancing Nutrients

Over-fertilization is another potential reason for green peace lily blooms. These plants require minimal fertilizer to thrive, so be cautious not to overdo it. Excessive nitrogen and iron in fertilizers can lead to increased chlorophyll production, resulting in green blooms. According to Soak and Soil, it’s essential to use a balanced fertilizer specifically designed for peace lilies and follow the recommended application rates.

By paying attention to the light exposure, water intake, and nutrient balance for your peace lily, you can promote healthier, whiter blooms and avoid the green tint that can sometimes develop.

When to Seek Professional Help

If you find that your peace lily flowers are turning green, there could be several reasons behind this occurrence. In most cases, changes in color are a natural part of the aging process. However, sometimes the issue might be associated with growing conditions and care. It’s essential to know when to seek professional help when trying to address these changes in your peace lily.

One of the reasons for your peace lily flowers turning green might be related to over-feeding. Peace lilies have low fertilizer needs, so providing too much can result in less striking flowers. If you think over-fertilization might be the issue, consult with a gardening professional to help determine the correct feeding schedule for your plant.

Another factor that can contribute to green flowers is the amount of light your peace lily receives. Excessive direct sunlight may cause flowers to turn green, while insufficient light might produce similar results. In such cases, seeking advice from a gardening expert can help you find the optimal balance of lighting conditions for your peace lily.

When it comes to changes in your peace lily flower’s color and overall plant health, some factors to consider include:

  • Aging of the plant
  • Too much or too little light exposure
  • Over-fertilization
  • Difficulty adjusting to new environmental conditions

If you’ve tried adjusting lighting and fertilization levels without success, it’s time to seek professional help. Reach out to your local nursery or gardening center for assistance in determining the exact cause of your peace lily’s green flowers.

In conclusion, if you’re unable to pinpoint the cause of your peace lily’s green flowers, consult a gardening professional for tailored advice. Proper care and attention to your plant’s growing conditions can help preserve your peace lily’s beautiful flowers and ensure its long-term health. Remember, keeping your plant healthy and thriving is the ultimate goal.
