Friendship Plant Facts

Friendship plant is relatively low maintenance, especially considering the medium it is most commonly found in.

Pilea involucrata does not generally require repotting. Small divisions from the parent plant can be carefully removed and replanted in a moist, well-draining substrate.

The friendship plant produces small runners that can be used to aid in propagation.  


Friendship plant stands out in any enclosure due to their unique and stunning foliage.

The leaves of this plant are dark green and can almost appear luminescent when the right amount of light is present.

The leaves are heart-shaped and can reach up to five inches in length.

The underside of these leaves may appear either darker or lighter, which adds an extra eye-catching look to the surface of the plant. 


Pilea involucrata is a tropical plant and is most comfortable in high humidity and warm climates.

In its natural habitat, the friendship plant is found on the edges of forests and in the shade of trees.

This plant usually reaches its maximum of 12 inches in height, making it an ideal plant for individuals with limited growing space.

PH Preference

Pilea involucrata prefers soil with a slightly acidic pH of between 5.0 and 7.0.

This type of soil is usually fairly moist and usually contains leaf mold and/or peat moss for drainage.

To mimic the natural conditions of its original habitat, individuals should aim for well-drained and not overly wet neutral soil. 

Vivarium Type

The friendship plant is quite an easy-going species.

With that in mind, it will not be too complicated when it comes to choosing the type of enclosure it is grown in.

It is best to try and replicate the plant’s natural habitat as much as possible.

Doing so will make it easier to provide this foliage plant with its basic needs.

The proper setup and theme of the enclosure will make a big difference to the overall look and health of the plant.

Be sure to choose setups that are moist and high in humidity. 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

As long as the soil is moist but not overly wet, this plant can be placed almost anywhere within a vivarium.

Since it only grows to a maximum of 12 inches, Pilea involucrata serves as a perfect mid-ground foliage option while still being able to fit among most other types of foliage or hardscape.


The friendship plant prefers damp, loamy terrarium soil that drains quickly yet still retains moisture.

A substrate made of vermicompost, coconut fiber, and perlite is a great place to start when creating the ideal environment for Pilea involucrata.

This plant also does well in terrariums that are kept moist from the condensation that will build within the wall of the container.


Since Pilea involucrata originates from tropical regions, bright and somewhat indirect lighting is best for this plant.

Aim for cooler color temperatures from your lighting source, as excessively hot temps will cause the leaves to scorch and dry out.

In most cases, placing the friendship plant near indirect and diffused terrarium light sources should provide for its proper growth.

Friendship Plant Care and Propagation

Since this plant does not require repotting, its care is relatively low maintenance.

This plant is an efficient self-propagator, meaning the plant will produce small offshoots or runners that can be carefully divided and replanted in the substrate of a terrarium in order to create an even more lush look. 

How to Grow

The friendship plant responds well to warm temperatures, moisture, and bright indirect light.

When propagating, it is important to make sure the soil is evenly moist and not completely soaked.

The friendship plant grows quickly and is able to spread diffusely within a terrarium due to its ability to produce offshoots.


The friendship plant requires regular, consistent watering. The soil should be kept evenly moist at all times, especially during its active growing period.

This plant is particularly sensitive to drought and should never dry out entirely.

Be aware that allowing the soil to become too wet will increase the risk of root rot.
