Why Is My Pink Syngonium Plant Turning Green?

Understanding the Color Change in Pink Syngonium Plants

Pink Syngonium, also known as the Arrowhead plant, is a popular houseplant known for its beautiful pink and green variegated leaves. However, there are instances when plant owners notice a shift in color from the distinctive pink to a more common green. This change can be disheartening, but understanding the reasons behind it can help plant enthusiasts take the necessary steps to either reverse the process or ensure the plant remains healthy despite the color transformation.

Lighting Conditions

One of the primary reasons for the color change in Pink Syngonium plants is the amount of light they receive. These plants are naturally adapted to relatively low light conditions, as they would typically grow under the canopy of larger trees in their native habitat. In a home environment, they require bright but indirect light in order to maintain their vibrant pink hues. When a Pink Syngonium is exposed to too much direct sunlight, the leaves may become stressed and revert to green as a protective measure to reduce the potential for damage. Conversely, insufficient light can also lead to a loss of variegation because the plant will prioritize chlorophyll production to maximize photosynthesis, resulting in greener leaves.

Nutrient Availability

Nutrients also play an essential role in the coloration of Pink Syngonium plants. A lack of essential nutrients, particularly nitrogen, can cause the pink variegation to fade. Nitrogen is a critical component of chlorophyll, the molecule that gives plants their green color and is vital for photosynthesis. If a plant isn’t receiving adequate nutrients from the soil, it may start to prioritize the growth of green, chlorophyll-rich leaves to compensate for the nutritional deficit. Regular fertilization with a balanced, water-soluble fertilizer during the growing season can help maintain the plant’s vibrant pink coloration.

Genetic Factors and Aging

As Pink Syngonium plants grow older, their leaves may naturally transition to a darker green color. This is a result of the plant’s maturity and genetic predisposition. Some of the pink variegation in these plants can be unstable, meaning that as the plant ages, its newer leaves might lack the pink pigment. When purchasing a plant, it’s worth noting that those with more pink variegation may sometimes be more prone to this loss of color as they age compared to those with more balanced variegation.

Propagation Practices

The method of propagation can influence the coloration of Pink Syngonium plants. If the plant is propagated using tissue culture, where a small part of the plant is used to grow new plants under laboratory conditions, there might be a higher chance of maintaining the pink color. However, if the plant has been propagated through cuttings, particularly from a plant that is already turning green, the resulting offspring are likely to carry on that trait. It is important for those wanting to propagate their Pink Syngonium plants to take cuttings from parts of the plant that display the desired coloration.

Environmental Stress

Environmental stress can also trigger color change in Pink Syngonium plants. This can include fluctuations in temperature, improper watering practices (either over or under-watering), and low humidity. These stressors can lead to a focus on survival rather than maintaining the characteristic pink coloration. It is crucial to keep an eye on the plant’s environment and make appropriate adjustments as needed to minimize stress.


There are several reasons why a Pink Syngonium plant may start turning green, ranging from lighting conditions and nutrient availability to genetic factors and environmental stressors. To encourage the retention of the pink coloration, it is essential to provide the right balance of indirect sunlight, nutrients, and a stable environment conducive to growth. With proper care and attention, Pink Syngonium plants can continue to show off their stunning variegated leaves, adding a touch of color and sophistication to any plant collection.
