What is Syngonium rayii?

Member of the Araceae family, Syngonium rayii is an eye-catching indoor plant, showcasing arrowhead-shaped leaves that feature a stunning contrast of intricate silvery-white venation against a dark green backdrop.

This indoor plant has the ability to absorb volatile organic compounds (VOCs) such as formaldehyde, benzene, and xylene. Incorporating this tropical beauty into your living space will not only enhance the visual appeal but also contribute to a healthier indoor atmosphere.

Syngonium rayii vs wendlandii

Syngonium Rayii and Wendlandii are two popular choices. While they may look similar at first glance, there are several key differences between the two.

  • Appearance: Syngonium Rayii has arrow-shaped leaves, while Wendlandii has heart-shaped leaves. Additionally, Syngonium Rayii has smaller leaves compared to Wendlandii.
  • Foliage Color: The leaves of Syngonium Rayii are dark green with silver-white veins, while Wendlandii has lighter green leaves with silver veins.
  • Growth Habit: Syngonium Rayii grows in a compact, bushy manner, while Wendlandii has a more vining growth habit. As a result, Wendlandii may require more support to keep it from trailing onto the ground.

Ideal Pot Size

A 4-6 inch pot with drainage holes is ideal for a young Syngonium rayii. As the plant grows, you may repot it into a one size larger pot. The trick lies in choosing a container that is slightly bigger than the plant’s root balls so they get enough space to grow without pooling excess water. Ensure to drill enough holes to aid drainage.

Syngonium rayii Plant Propagation 


One of the best and easiest methods to propagate Syngonium rayii is through stem cuttings during spring or early summer. Here’s how to do it:

  • Look for a healthy, mature stem on the mother plant that has at least 2-3 leaves and one or more aerial roots along the length of the stem.
  • Use a clean, sharp pair of pruning shears or scissors to make a cut about half an inch below the aerial root.
  • Dip the cut end of the stem in a rooting hormone powder, which can stimulate faster root growth.
  • Plant the stem in a pot with well-draining soil, making sure to bury the bottom node of the stem.
  • Keep the soil moist and place the pot in a bright, indirect light.

Wait for the roots to develop, which can take a few weeks. Hold back on watering and let the plant acclimate to your indoor environment.

Syngonium rayii Care


Syngonium rayii thrives in bright, indirect light, which mimics the dappled sunlight it receives under the canopy in its natural habitat. East or north-facing windows often provide ideal lighting conditions. Alternatively, you can use fluorescent lights or LED grow lights to supplement natural light, especially during winter months when daylight hours are shorter


For optimal growth, Syngonium rayii requires a well-draining, nutrient-rich soil mix that also retains some moisture. In addition to peat moss, perlite, and vermiculite, consider adding a small amount of compost or well-aged manure to increase nutrient content. The ideal soil pH for the plant is between 5.5 and 6.5. If using garden soil, amend it well with a handful of gritty sand to aid drainage.


Syngonium rayii prefers to be kept consistently moist but not waterlogged. To ensure the same, follow a weekly deep watering session—saturate the medium until the excess water drains away from the holes. This will ensure proper moisture balance in the medium without pooling it.

Always use room temperature, filtered, or dechlorinated water to avoid shocking the plant or introducing harmful chemicals. During hotter months or when the plant is in a growth spurt, it may require more frequent watering. In contrast, during cooler months or when growth slows down, reduce the watering frequency to prevent waterlogged soil.

Temperature and Humidity

Syngonium rayii prefers a wide temperature range between 45-95 F or 7-35 C. However, avoid sudden temperature fluctuations and protect the plant from cold drafts or heating vents.

The plant prefers high humidity of about 60-80%. If the air is too dry, the leaves may turn brown at the tips. To increase humidity, you can place the plant on a tray of pebbles filled with water or use a humidifier. Misting the leaves with tepid water or grouping humidity-loving plants together will boost the air moisture.


This plant benefits from regular fertilization during the spring and summer. Using a balanced, water-soluble fertilizer is crucial, but you can also opt for a slow-release granular fertilizer or organic alternatives like worm castings or fish emulsion. Always dilute the fertilizer to 1/2 its strength feed them once in 4-6 weeks to provide optimal fertilization.

Additionally, it’s good practice to flush the soil every few months to prevent the build-up of excess salts from fertilizers. Do not fertilize the plant during the plant’s dormancy in winter.


Regular pruning not only encourages bushier growth and removes dead or damaged leaves but also helps maintain the desired shape of your Syngonium rayii. Keep an eye out for any signs of pests or diseases while pruning, and sterilize your pruning tools before and after use to prevent the spread of pathogens. If your plant becomes too leggy, you can also pinch off the growing tips to promote branching.

Major Troubleshooting Tips

  • Wilted or Yellow Leaves: Majorly a sign of overwatering. Let the soil dry out slightly before watering again. Also, move the plant to a spot with indirect light.
  • Curling or Crispy Leaves: Curling or crispy leaves are often a sign of low humidity levels. Try misting the plant regularly or placing it on a tray of pebbles filled with water.
  • Leggy or Sparse Growth: Occurs due to lack of sunlight. Move the plant to a brighter spot or consider providing artificial light.
  • Pests: Common pests that can affect Syngonium rayii include spider mites, mealybugs, and scale insects. Regularly inspect the plant for visible signs such as cottony webbing or powdery undersides. Remove them using insecticidal or neem oil spray.
