Hands-on With Syngonium erythrophyllum ‘Llano Carti Road’

A relatively new species – named for the road in which it was found by in Panama – Syngonium erythrophyllum ‘Llano Carti Road’ is a true dark beauty.

With leaves that range from a deep green to an almost rich dark chocolate color, each with a crimson underside, it’s a gorgeous species to add to a terrarium.

For an Arrowhead Vine, it doesn’t appear to form those characteristic arrow-shaped leaves until it’s reached a certain level of maturity.

Though it still vines aggressively like a Syngonium doesand with its foliage being on the larger side at 3-4 inches, it’s definitely more suited to larger terrarium containers.

Given that Syngonium are a genus full of fantastic low light terrarium plants, and darker leaves tend to indicate plants that can handle lower light levels (and this plant is really dark) it’s fair to assume this species is pretty adaptable.

That being said, it’ll probably do better under bright, indirect light, and it’s definitely one to keep out of direct sunlight.


This tropical plant species has fairly high watering requirements and should thrive in an evenly moist (but not soggy) tropical environment.

Watering Syngonium erythrophyllum ‘Llano Carti Road’
I tend to water my Syngonium as soon as the substrate is dry to the touch.

Using a pot with a drainage hole is the best way to meet this plant’s thirsty water requirements without the risk of overdoing it.

Otherwise, you risk root rot if your plant is sat in saturated soil for too long.

Watering Syngonium erythrophyllum ‘Llano Carti Road’
Simply stop when you see water pooling in the tray.


Syngonium erythrophyllum ‘Llano Carti Road’ should thrive in most tropical substrate mixes. Typical mixes with excellent water retention and drainage should do the trick.

I always like to use a coco coir base for its fluffy texture, supplemented with orchid bark (and/or perlite or pumice) and earthworm castings.

Temperature & Humidity

Being a tropical species, Syngonium erythrophyllum ‘Llano Carti Road’ really appreciates a hot and humid environment, though it doesn’t seem to be particularly sensitive to either requirement.

Maintaining both at a moderate level will ensure your plant remains healthy and happy.

Syngonium erythrophyllum ‘Llano Carti Road’ is a fairly prolific vining plant with a scandent growth pattern.

Where other Syngonium species will form more compact, bushy foliage, this plant tends to creep outward much more.

As with other Syngonium species, this plant is easy to propagate through stem cuttings.

You can take a cutting from the tip or a stretch of the vine as long as they have some viable root nodes.

Varieties & Similar Plants

There are other varieties of Syngonium erythrophyllum currently on the market, such as Syngonium erythrophyllum ‘Red Arrow’, but to be honest, I can’t see much of a difference. As far as I can tell, they’re the same plant.

For more Syngonium species with lovely colours, see the dusty pink Syngonium ‘Neon Robusta’ and the creamy white Syngonium podophyllum ‘Pixie’.

Common Problems

Syngonium is a pretty bulletproof genus of plant,  so as long as you’re growing Syngonium erythrophyllum ‘Llano Carti Road’ in a typical tropical setup, you’re unlikely to run into any major problems.
