Dragon’s Tongue Facts

Hemigraphis repanda is also known as Dragon’s Tongue due to its coloration and oval-shaped leaves.

This plant is relatively small and grows no taller than a height of 12 Inches.

Its leaves are a purple to deep pink color but can vary darker and brighter depending on its environment.

This plant is a slow grower, so it’s great for filling in spaces that are bare in appearance and does not require constant pruning.


Hemigraphis is recognizable due to its vibrant foliage and wide leaves.

This plant has a trailing growth habit, so it tends to be used as a filler in areas with empty spaces or underneath taller plants.

The leaves on this plant are usually widened when they are hydrated and shrink when they appear to be lacking in water or nutrients.

This plant’s leaves are oval in shape and usually arranged in pairs when growing on the stem.


Dragon’s Tongue originates from the tropics of Southeast Asia, so it’s commonly found in moist, humid environments.

This plant is found at the base of trees and often on the forest floor.

When kept in a terrarium, its preferred temperature is a range of 65°F to 80°F, and prefers temples on the warmer side.

PH Preference

Hemigraphis has a broad pH range as it can do well in acidic or alkaline soil with a range of 6.0 to 7.0 being ideal.

In the tropics, this plant is found in between bark and moss, indicating lovely acidic or just neutral soil.

Vivarium Type

There is no set type of enclosure that the Dragon’s Tongue must be grown in. In fact, they can do very well in a variety of vivarium types.

One of the most important things to keep in mind when choosing the appropriate enclosure is the amount of space available.

In addition, Hemigraphis repanda should also be provided with tropical and moist terrain areas.

Here are recommended vivariums it will do well in:

  • Paludariums – Half aquatic/ half terrain-based enclosure.
  • Terrariums – Fully terrain-based enclosures with little to no aquatic features.

Vivarium Placement

This plant is mainly grown as a foreground or midground plant providing a contrasting color to the foliage around it.

This plant works well when added to taller hardscapes because it can help to trap water and maintain moisture for a longer period of time.

Dragon’s Tongue can also be placed in the background of an enclosure to add a pop of color and some texture variety.


Hemigraphis does very well in a soil-based terrarium substrate with a medium-to-high amount of organic material.

This plant adapts well to different textures of substrate but prefers a medium- to high-density substrate.

The vibrant plant should not be planted in sand or akadama as it will not be able to work itself into the substrate and grow properly.


Dragon’s Tongue prefers to be in the medium to low range when it comes to terrarium lighting.

This plant is perfect for vivariums looking to establish medium to high light without it being terribly bright.

However, due to its bright foliage, it needs some direct sunlight to achieve its fullest potential.

Aim for cooler temperature bulbs that will mimic overcast days or lightly shaded areas.

Buy Dragon’s Tongue Plant

When it comes to buying a Dragon’s Tongue, there are a few things to keep in mind.

Making sure that the plant being bought is healthy is essential for its success in a vivarium.

Vegetation that is already in poor conditions, will have a very hard time adjusting to new environments.

In addition, always check the foliage closely for yellowing, wilting, black spots, or any signs of damage.

Pay close attention and look for any pests or fungal diseases. Inspect both sides of the leaves to avoid missing any red flags.

Dragon’s Tongue Plant Care and Propagation

Dragon’s Tongue is extremely easy to care for due to its low-maintenance requirements.

This plant does not need to be pruned much as it grows in a way that allows it to stay at manageable heights.

Unfortunately, this plant does not propagate easily so it is recommended to pick up rooted cuttings from reliable vendors. 

How to grow

This plant is quite easy to grow but not so easy to propagate. When sourcing Hemigraphis repanda, try to pick up a pre-rooted piece from a reputable vendor.

Place the plant in the substrate lightly and it should take a few weeks for it to attach its roots.

Once it has taken root and started to grow, keep up with regular watering so that it can remain hydrated and healthy.


Hemigraphis prefers moist substrates with occasional watering one to two times a week.

In general, allow the media to dry out in between waterings but don’t let it get bone dry.

If it appears to be drying out rapidly, try increasing the humidity around the enclosure. If there is a massive leaf curl, too much water will be the culprit.
