Syngonium Erythrophyllum – Basic Characteristics

The Syngonium Erythrophyllum goes by many names, such as the “Red Arrow” or “Llano Carti Road.” Gardeners consider this plant to be a rare kind of Syngonium plant.

The Syngonium Erythrophyllum is a tropical plant that is categorized under the Syngonium genus of plants. In the natural world, this plant is found in southern or central America.

The Syngonium Erythrophyllum is an epiphyte – this means that in its natural environment, the plant climbs up trees within its proximity. Due to its rarity, the plant is commonly sought out by rare plant collectors and home gardeners.

So, if you’re a plant collector or if you’re planning to start collecting rare plants, we recommend getting this plant.

The Foliage

The Syngonium Erythrophyllum has stunning foliage. This plant sports narrow leaves which are arrow-like in shape. Their wavy texture and dark green hue come into perfect contrast with their reddish-brown undersides, which takes the plant’s beauty to the next level.

The Flowers

The Syngonium Erythrophyllum boasts flowers that resemble the flowers of other aroid plants. The spathe of this plant is found in 2 main varieties: white or green with a dull, spiky inflorescence with a hint of yellow hue. It is, however, rare to see a Syngonium Erythrophyllum bloom flowers in home gardens.

Height and Width

When properly cultivated indoors, your plant will grow up to 6 to 7 feet (around 1.8 meters) in length. For this reason, it is common practice to hang this plant from pots or to plant them next to wet walls (for climbing).


Unfortunately, the Syngonium Erythrophyllum is known to be toxic. This means that if you have animals inside your home who risk chewing on this plant, it is best not to get this plant for yourself.

Syngonium Erythrophyllum – Top 5 Caring tips

Now that we are better acquainted with the Syngonium Erythrophyllum, it is time to discuss the top ways one can care for this plant to optimize its growth indoors.

Light Requirements

The Syngonium Erythrophyllum thrives when kept in bright, indirect sunlight. As an epiphyte, this plant is well adapted to climbing on trees to receive dappled sunlight filtered through other plants without direct exposure to the sun.

If you don’t know a place in your home where your plant can receive light in this way, a good hack is to keep this plant near a large window covered by a thin curtain. This will allow your plant to receive ample sunlight without it directly reaching your plant.

If you expose your plant to too much sunlight, you will end up scorching its leaves. If you keep it in the shade for too long, your plant’s growth will halt, and its leaves will begin to discolour.

Temperature Requirements

The ideal temperature for the Syngonium Erythrophyllum plant is between the range of 15 degrees Celsius to 30 degrees Celsius (59 -86F).

This means that in most cases, you do not need to worry about the temperature too much since the average room temperature for most regions lies within this range. Make sure you don’t expose it to really low temperatures (below 12 degrees Celsius), or its growth will be stunted.

Water Requirements

Syngonium Erythrophyllums usually thrive when watered regularly. Since it is not drought tolerant, you should make sure that you water it promptly before it dries out. Make sure, though, that you don’t water it too much. Excess watering can cause your plant’s roots to rot.

Humidity Requirements

Being a tropical plant, your Syngonium Erythrophyllum will need a lot of surrounding humidity to grow optimally. If the humidity levels are too low, your plant’s leaves will start turning brown, and your plant will become prone to diseases and infections.

The ideal humidity levels for this plant lies around 70 to 80 percent. If you’re unable to provide this humidity level to your plant naturally, investing in a humidifier will be a good idea.

Soil Requirements

The Syngonium Erythrophyllum thrives in soil that is well-draining, moisture-retentive and is a bit acidic.

A good soil mix to put your plant in can be equal portions of standard potting soil, bark and perlite and a bit of horticultural charcoal. Grow your Syngonium Erythrophyllum in this soil mix, and your plant will thank you for it.

How do I propagate a Syngonium Erythrophyllum indoors?

Now that we understand how we can take care of this plant inside our house, it is time to discuss the method for this plant’s propagation.

Overall, propagating a Syngonium Erythrophyllum is relatively straightforward. All you need to do is strictly follow the steps we’ve outlined for you below, and you will be good to go.

The propagation of a Syngonium Erythrophyllum is best done during spring or early summer. This is because your plant will be in its growing phase during this time; hence propagating it will be easier.

It is also recommended that you propagate this plant using water instead of soil. We say this because of 3 main reasons:

  • The plant has deep roots which grow faster in water as compared to soil.
  • Rooting this plant in water tends to minimize the chances of its stem rotting, and it reduces the chances of your plant catching diseases.
  • Rooting in water comes with the added bonus of being able to see your plant’s roots as they grow. This way, you can keep track of its progress.

Propagation Procedure:

The procedure for propagating a Syngonium Erythrophyllum is as follows:

  1. Use a sharp (Sanitized) blade and cut off a few inches of the plant’s stem.
  2. Cut the stem off from half an inch below the leaf nodes and make sure your nodes have aerial roots (they root faster).
  3. Place these cuttings in a glass of room temperature water and place your jar somewhere it receives bright, indirect sunlight.
  4. To preserve the moisture around the plant, cover your container with a plastic sheet (make sure you don’t cover the plant, though).
  5. It is good practice to change the water of your container every 6- 7 days to prevent bacterial growth.
  6. In about 2 weeks, you should start seeing the development of the roots.
  7. When the roots have reached a length of at least 3 inches, you may relocate your plant and place it in a well-draining potting mix.
  8. Water your plant well and make sure you follow the caring tips outlined above to optimize its growth

Bottom Line

The Syngonium Erythrophyllum will make for a great addition to your usual crowd of houseplants. The plant requires moderate oversight to grow properly but will, for the most part, not require any extra care as it grows. Follow the steps outlined above to correctly propagate this plant inside your home.
