Anthurium flowers are known for their vibrant colors and attractive spathes, making them a popular choice for plant enthusiasts. However, it can be concerning when these once-colorful blooms start turning green. Understanding why this occurs and what can be done to preserve the desired hue is essential for anyone cultivating these plants.

There are a few reasons why anthurium flowers might turn green, with one of the most common causes being insufficient light. Anthurium plants require bright, indirect sunlight to maintain their health and colorful blooms. If your anthurium flowers are beginning to turn green, it may be necessary to reposition the plant or introduce artificial lighting. Another factor that can contribute to the color change is forced flowering due to greenhouse practices, which may cause the plant to lose its color as it ages or when it doesn’t get a long enough dormancy period during its second flowering.

Ensuring proper care is crucial for maintaining the vibrant colors of anthurium flowers. By addressing the contributing factors such as lighting and potential environmental stressors, it is possible to better understand the reasons behind the green coloration and take appropriate steps to restore your anthurium’s vibrant hues.

Why Anthurium Flowers Turn Green

Genetic Factors

Certain species of anthuriums are naturally predisposed to have their spathes turn green over time. These plants begin with a different and more vibrant color, which gradually transitions to green as they mature. This natural process is inherent to the species and not a cause for concern.

Environmental Factors

One primary environmental cause of anthurium flowers turning green is inadequate lighting. Anthurium plants thrive in bright, indirect light, which is essential for maintaining their vibrant colors. Therefore, if your anthurium’s blooms are turning green, consider relocating the plant to a brighter area or supplementing with artificial light [^2^].

Another potential environmental factor involves cultivation practices. In some cases, greenhouse techniques may force anthurium plants to flower before they are ready, causing them to lose color as they age. Moreover, if the plant doesn’t receive a long enough dormancy period during its second flowering, the spathe may also fade to green [^3^]. To maintain optimal coloration, be mindful of these factors and provide the necessary growing conditions for your anthurium.

In summary, genetic factors and environmental conditions are the primary reasons behind anthurium flowers turning green. By being mindful of your plant’s specific needs and providing the appropriate care, you can best maintain the vibrant colors of your anthurium blooms.

How to Maintain Anthuriums for Vibrant Flowers

In this section, we will discuss several factors that contribute to helping your Anthurium flowers maintain their vibrant red color, preventing them from turning green.

Proper Lighting

Anthuriums thrive when provided with bright, indirect light. Placing them near a window with a sheer curtain can protect them from direct sunlight while still receiving enough light. Adequate lighting is essential for the plant’s overall health and can contribute to maintaining the vibrant color of its flowers. Avoid exposing your Anthurium to direct sunlight, as it can harm the plant and possibly cause the flowers to turn green.

Ideal Temperature and Humidity

Anthuriums originate from tropical regions, so they prefer warm temperatures and high humidity conditions. Ensure that the temperature remains above 65 degrees Fahrenheit and maintain humidity above 65 percent to keep your Anthurium healthy and its flowers vibrant. You can create extra humidity by placing a tray filled with water and pebbles underneath the plant or using a humidifier in the room.

Fertilization and Soil Requirements

For healthy growth and consistent flowering, use a well-draining, peat-based or pine bark potting mixture. Adding perlite or volcanic rock to the mixture can help aerate the roots and improve drainage. Fertilize your Anthurium every six weeks using a balanced, water-soluble fertilizer. Avoid over-fertilizing, as it can lead to problems like root burn and might affect the flower color. Regularly removing dead or yellow leaves and flowers will encourage new growth and help maintain the red hue of Anthurium flowers.

By following these recommendations regarding proper lighting, ideal temperature, humidity conditions, and fertilization, your Anthurium flowers should maintain their stunning red color and remain vibrant throughout the season.

Common Anthurium Problems and Solutions

Pest Control

Anthurium plants may face issues related to pests, such as aphids, mealybugs, or spider mites. To treat these pests, start by blasting the plant with a strong spray of water to remove as many pests as possible. Then, treat the plant with a natural insecticidal soap or a pesticide specifically designed for indoor plants. Regular inspection and prompt treatment will keep pest issues at bay.

Disease Management

Anthuriums are generally low maintenance; however, they can be prone to certain diseases, such as root and stem rot, and bacterial or fungal infections. To prevent these issues, ensure proper drainage and avoid over-watering. If you notice signs of infection like yellowing leaves or soft stems, you might have to repot the plant using fresh, well-draining soil.

If you find green anthurium flowers, it could be a sign of inadequate lighting. Anthurium plants need plenty of indirect bright light to maintain their vibrant color. To remedy this, try moving the plant to a brighter spot or adding artificial light. Splitting the text into several paragraphs makes it easier to read and understand.


In summary, the main reason for anthurium flowers turning green is due to a lack of sufficient light. To address this issue, make sure you place your anthurium in an area with bright, indirect sunlight, which will help maintain the vibrant colors of the blooms. Another factor to consider is the plant’s natural aging process, as some flowers may lose their color with age.

Keeping your anthurium healthy and vibrant is not a complicated task. By taking some simple steps in the plant’s care, you can enjoy its stunning colors for a longer time. Remember to maintain proper watering practices and provide the necessary nutrients to ensure continuous growth and flowering.

Additionally, it’s important to monitor your anthurium regularly for signs of stress, like yellowing leaves or fading flowers, which may be an indication of issues related to lighting, nutrient imbalance or improper care. By taking prompt action to address the problem, you can prevent further damage and help your anthurium return to its full health.

Ultimately, by providing the right care and environment for your anthurium, you can enjoy its beautiful, colorful flowers all year round. Keep in mind that some natural color changes might occur, but as long as you’re paying attention to its needs, you should be able to maintain healthy, vibrant blooms for a long time.

Frequently Asked Questions

Anthurium Flower Color Change

Anthurium flowers may change color, often turning green, due to various reasons such as age, dormancy periods, and greenhouse practices. As the spathe ages, it may fade, and some green will start creeping in from the edges. It is essential to provide your anthurium with proper care conditions to maintain vibrant flower colors.

Green Anthurium Flower Care

Caring for green anthurium flowers involves providing the right balance of light, temperature, water, and fertilization. Ensure that your anthurium is placed in a well-lit area with indirect sunlight, maintaining a temperature range of 65-75°F. Water the plant only when the top layer of soil is dry, and fertilize using a balanced liquid fertilizer once every 6-8 weeks.

Factors Influencing Flower Color

Several factors can influence anthurium flower colors, including light levels, temperature, and overall plant health. Exposure to too much direct sunlight or inadequate light can affect flower coloration. Maintaining consistent and suitable temperature is vital, as fluctuations can negatively impact flower appearance and plant health.

Green Anthurium Vs Red

Green and red anthuriums differ mainly in their spathe color, which is influenced by genetics, age, and environmental factors as mentioned earlier. The care requirements for both green and red anthuriums are generally the same, focusing on proper light, watering, fertilization, and temperature management.

Anthurium Flower Stage Progression

As anthurium flowers age, they undergo various stages of development. New flowers may start small and bright with vibrant colors, gradually fading and darkening as they mature. Eventually, the spathe may turn green and eventually wilt, indicating the end of its lifecycle. Regularly prune spent flowers to encourage new growth.
